Повний текст джерелаRoot-knot nematodes (Meloidogyne species) are the major soil-borne pests of tomato (Solanum lycorpesicum) plants. Due to the global withdrawal of effective chemical nematicides from the agrochemical markets, nematodes are difficult to control under the production systems. Currently, botanicals are being researched and developed as alternative to chemical nematicides with promising results, although they have challenge of phytotoxicity. The objective of this study was to determine the Mean Concentration Stimulation Point (MCSP) of Tickberry (Lantana camara) extracts for tomato plant-infected with M. javanica. Treatments consisted of six levels of L. camara extracts, namely, 0, 2, 4, 6, 8 and 10% per pot, which were arranged in a randomised complete block design, with ten replicates. Tomato seedlings were inoculated with 2500 second-stage juveniles (J2S) of M. javanica at five days after transplanting, with treatments applied at seven days after inoculation. At 56 days after inoculation, L. camara extracts had positive effects on plant height, stem diameter, number of leaves, number of fruits and fruit mass, contributing 65, 74, 61, 25 and 61% in total treatment variation (TTV), respectively, under greenhouse conditions. Under microplot conditions, treatments contributed 55, 85, 61, 36 and 85% in TTV of the respective plant variables. Under greenhouse it contributed 60, 35 and 77% and 29, 79 and 70% under microplot on dry shoot mass, dry root mass and galling index respectively. Treatments did not have any effects on soil pH and electrical conductivity (EC). Under greenhouse conditions, treatments contributed 88, 94 and 92% in TTV of nematode in roots, soil and final population, respectively, whereas under microplot conditions 94, 97 and 95% in xvii TTV of the respective nematode stages. The derived mean concentration of L. camara extracts for tomato was 5.76 and 5.31% under microplot and greenhouse conditions, respectively. The overall sensitivity of tomato plants to L. camara extracts under microplot and greenhouse were 3 and 0, respectively. In conclusion Meloidogyne species can be managed using L. camara extracts 5.31 and 5.76% under glasshouse production and field production system respectively.

Повний текст джерелаRalstonia solanacearum es uno de los patógenos bacterianos de plantas más devastadores del mundo. Esta bacteria del suelo es el agente causante de la marchitez bacteriana en más de 450 especies de plantas y causa una devastación severa en cultivos de solanáceas como el tomate. R. solanacearum accede al sistema radicular a través de heridas y sitios de emergencia de raíces laterales y luego se desplaza hasta la vasculatura radicular, donde se multiplica en el xilema y luego se disemina verticalmente a través del xilema y horizontalmente entre los vasos y los tejidos circundantes. Hasta la fecha, la estrategia de manejo más fiable para controlar R. solanacearum ha sido el uso de resistencia genética. En tomate, entre las mejores fuentes de resistencia se encuentra el cultivar resistente Hawaii 7996 (H7996), que se usa comúnmente como patrón en el cultivo comercial de tomate. Este cultivar resistente ha desarrollado mecanismos de defensa efectivos para prevenir la colonización de vasos o el movimiento entre vasos una vez que ha ocurrido la colonización vascular. Publicaciones recientes muestran que el cilindro vascular del xilema de la raíz actúa como tejido predominante para montar una respuesta de defensa eficaz contra los invasores vasculares, lo que restringe el avance del patógeno hacia el tejido aéreo. Sin embargo, los mecanismos que regulan esta forma de resistencia siguen siendo desconocidos en gran manera. Desentrañar los mecanismos a través de los cuales las plantas bloquean o ralentizan la progresión de patógenos en la vasculatura del xilema de la raíz puede ser vital en el desarrollo de cultivares resistentes mediante intervenciones biotecnológicas. Por lo tanto, en esta tesis intentamos arrojar luz sobre las respuestas de defensa que actúan en la vasculatura del xilema de la raíz que restringen efectivamente la colonización por el patógeno bacteriano vascular R. solanacerum en tomate. Los estudios histopatológicos comparativos en líneas de tomate resistentes y susceptibles indican que un refuerzo vascular compuesto de ferulatos, que culmina en la formación de una zona ferulo-suberínica, puede actuar como una fuerte barrera físico-química contra la invasión de R. solanacearum (Capítulo 1). Esta barrera fenólico-alifática refuerza las paredes del tejido vascular del xilema en H7996 y puede restringir el movimiento de la bacteria desde la luz del vaso del xilema hacia el xilema circundante, células del parénquima, vasos cercanos y espacios intercelulares. Los cambios de composición en las paredes se estudiaron mediante espectroscopia, lo cual mostró una intensa acumulación de metabolitos compatibles con la suberina específicamente en las raíces de H7996 resistente, tras la infección de R. solanacearum (Capítulo 2). Se observaron diferencias en el estado de polimerización de la lignina en las raíces después de la infección entre tomate resistente y susceptible. El H7996 contenía una mayor proporción de lignina de tipo G, que es más resistente a la degradación, mientras que Marmande susceptible contenía más lignina de tipo S, que es más propensa a degradarse. La expresión de genes de la vía biosintética de ácidos grasos de la suberina se incrementó significativamente en el tejido vascular del xilema de la raíz primaria de las plantas infectadas con H7996 en comparación con los controles o el tomate susceptible (Capítulo 3). Esto indica que la regulación positiva de estos genes es una respuesta específica de plantas H7996 resistentes que tiene lugar en la vasculatura suberizada tras la infección por R. solanacearum. Además, se observó inducción de ProSlFHT::GUS en la vasculatura del xilema de la raíz principal de las plantas H7996 infectadas, así como en tejidos que se sabe que depositan suberina tales como epidermis, exodermis y tejidos que experimentan cicatrización de heridas.
Ralstonia solanacearum is one of the world's most devastating bacterial pathogens of plants. This soil-borne bacterium is the causative agent of bacterial wilt on more than 450 plant species, and it causes severe devastation on Solanaceous crops like tomato. R. solanacearum gains access to the root system through wounds and lateral root emerging sites and then moves to the root vasculature, where it multiplies in the xylem and later spreads vertically within the xylem sap and horizontally between vessels and to the surrounding tissues. To date, the most reliable management strategy to control R. solanacearum has been the use of genetic resistance. In tomato, among the best resistance sources is the resistant cultivar Hawaii 7996 (H7996), which is commonly used as a rootstock in commercial tomato cultivation. This resistant cultivar has evolved effective defense mechanisms to prevent vessel colonization or movement between vessels once vascular colonization has occurred. Recent reports show that the root xylem vascular cylinder acts as a predominant tissue for mounting an efficient defense response against vascular invaders, restricting onward movement of the pathogen to the aerial tissue. However, the mechanisms regulating this form of resistance remain elusive. Unravelling the mechanisms through which the plants block or slow down pathogen progression at the root xylem vasculature can be vital in the development of resistant cultivars by biotechnological interventions. Hence, in this thesis we attempted to shed light on the defense responses acting at the root xylem vasculature that effectively restrict colonization by the vascular bacterial pathogen R. solanacerum in tomato. Comparative histopathological studies in resistant and susceptible tomato lines indicated that a ferulate vascular reinforcement, culminating into a ferulo-suberin zone, may act as a strong physico-chemical barrier against R. solanacearum invasion (Chapter 1). This phenolic- aliphatic barrier reinforces the walls of xylem vascular tissue in H7996 and may restrict movement of the bacterium from the xylem vessel lumen to the surrounding xylem parenchyma cells and nearby vessels and inter-cellular spaces. Compositional changes in walls were studied using spectroscopy, which showed strong accumulation of suberin- compatible metabolites specifically in roots of resistant H7996, upon infection of R. solanacearum (Chapter 2). Differences in the polymerization state of lignin in roots were observed after infection between resistant and susceptible tomato. H7996 contained a higher proportion of G-type lignin, which is more resistant to degradation, whereas susceptible Marmande contained more S-type lignin, which is more prone to degradation. Expression of genes from the suberin fatty acid biosynthetic pathway was significantly upregulated in the taproot xylem vascular tissue of H7996 infected plants compared to the mock controls or susceptible tomato (Chapter 3). This indicates that upregulation of these genes is a specific response of resistant H7996 plants that takes place in suberizing vasculature upon R. solanacearum infection. Further, induction of ProSlFHT::GUS was observed in taproot xylem vasculature of infected H7996 plants, as well as in tissues known to deposit suberin such as epidermis, exodermis and tissues undergoing wound healing. Implications of overexpressing genes from pathway of suberin and the associated soluble phenolics synthesis, were evaluated in susceptible tomato background. Overexpression of suberin feruloyl transferase (FHT), which catalyzes the formation feruloyl esters showed limited restriction against R. solanacearum. In contrast, overexpression of tyramine N-hydroxycinnamoyltransferase (THT 1-3), responsible for synthesis of hydroxycinnamic acid amides (HCAA) such as feruloyl tyramine resulted in an increase of resistance against R. solanacearum with disease progressing remarkably slower in this line compared to wild type plants. Accumulation of such aminated phenolics may act as a chemical barrier acting as phytoalexin but could also act as physical barrier if cross-linked to the poly-aromatic domain of suberin.

Повний текст джерелаPests and diseases are important factors to take into account in order to avoid losses in crop production. Nowadays, the search of new enviro-friendly compounds to induce defence mechanisms in plants to fight against plant diseases is a priority. Thus, the goal of this thesis has been to study the action mode of the enviro-friendly inducers of resistance copper-heptagluconate, 1-methyltryptophan (1-MT) and ammonium in tomato-P. syringae pathosystem. In general terms, Cu-heptagluconate induces phenolic compounds, 1-MT induces stomatal closure and affects apoplastic content and bacterial motility, and ammonium nutrition produces a primary metabolism reprogramming. Moreover, the study of changes at root level under nitrate and ammonium sources has been carried out, showing that the addition of nitrate or C compounds to ammonium treatment alleviates its mild toxicity.

Повний текст джерелаTomato (Solanum lycopersicum) has become a very important model for genetic and physiological studies in the last years, due to the presence of various mutants, including those with hormonal alterations. The ornamental dwarf tomato cv. Micro-Tom (MT) has been largely used because of its ability to produce viable fruits and seeds in pots of just 50-100 ml, completing its life cycle in seventy to ninety days. In an attempt to gain insights on the mechanisms that regulate plant growth under physiologic stress, homozygote hormonal double mutants of the MT were created and later on screened for the role of hormonal interactions in the control of root growth under osmotic stress. The experiment was conducted at ESALQ-USP Hormonal Control of Plant Development Laboratory, where genotypes of five double mutants namely diagetropica/sitiens (dgt/sit), diagetropica/epinastic (dgt/epi), diagetropica/Never ripe (dgt/Nr), sitiens/epinastic (sit/epi) and Never ripe/sitiens (Nr/epi) were produced in BC6Fn homozygosis. Germinated seeds of MT and the mutants sitiens (sit), Never ripe (Nr) and the double mutant Nr/sit were treated with PEG 6000 at different osmotic potentials. There were also experiments with chloro-2-ethyl phosphonic acid (CEPA), an ethylenereleaser (Ethrel) and the inhibitor of ethylene synthesis aminoethyoxyvinyl glycine (AVG). The parameters evaluated were radicle and hypocotyls growth, root/hypocotyl ratio and relative water content (RWC). The stem was more inhibited than the root at moderate osmotic stress (-0.6 MPa), which resulted in elevated root/hypocotyl ratio for MT, sit and, in lesser extent, Nr/sit. This pattern was not observed in Nr. A root swelling similar to that caused by ethylene was observed in sit at -1.1 MPa. This swelling was less evident in the double mutant Nr/sit. When added Ethrel, there was inhibition of root growth in sit and MT. A discrete root inhibition was also observed in the ethyleneinsensitive Nr mutant. In moderate osmotic stress (-0.6 MPa), root inhibition was more severe than in water for MT, but not for sit, until 1 µM Ethrel. The AVG application increased this difference between water and PEG 6000 treatments. It can be concluded that, in moderate water deficit, the root growth and root/hypocotyl ratio were increased, when compared to normal water supply. These findings are important, since they can provide for the better design of agronomic practices and crop improvement aiming at the enhancement of water use efficiency.

Повний текст джерелаDrought is the major abiotic plant stress factor. Among the mechanisms of water deficit resistance the root growth response has expressive importance. This response seems to be regulated by hormones. An interesting method to study hormone regulated processes is the use of hormonal mutants. The tomato cultivar Micro-Tom (MT) have reduced size and short life cycle and therefore constitutes an excellent genetic model for physiology studies. Hormonal mutants in MT with low endogenous ABA (sit and flc), ethylene insensitivity (Nr), ethylene overproduction (epi) and auxin insensitivity (dgt) constitute valuable tools to study hormone action in plant development.The present work aimed to study the hormonal interaction in the control of root growth of tomato MT subjected to water deficit. Germinated seeds of MT and mutants epi, sit, Nr, e dgt were placed in a black Ger-Box containing water and PEG 6000 solutions with potentials of - 0,3; -0,6; -0,9 e 1,2 MPa. After 5 days the length of root and hypocotyls were measured. Others experiments were conducted in Ger-Box containing ethylene action inhibitor, silver thiosulphate (STS), ABA biosynthesis inhibitor (Fluridone) and an ethylene releaser, 2-chloroethyl-phosphonic acid (CEPA) in different concentrations in water and in a -0,6 MPa osmotic potential PEG solution. After 5 days the length of the roots were measured. The PEG solution of 0,6 MPa promoted root growth in MT, dgt, epi and in with less intensity in Nr . The promotion of root growth did not occur in sit. In the mutant sit, low potential caused a swelling in the roots similar to excess ethylene symptoms. When CEPA was used, a severe inhibition of root growth occurred. The inhibition was less intense in dgt. In the 0,6 MPa solution the inhibition was more severe than occurred in water in MT. When ethylene action was inhibited by the application of STS, a greater difference of root growth between water and 0,6 MPa PEG solution occurred as the STS concentration increased. In the mutant dgt these differences were not observed. In the experiment with fluridone as the dose increased the inhibition in the root growth increased concomitantly. The inhibition was less severe in Nr and dgt. In higher doses of fluridone root ramification occurred, interfering in the primary root length. By these results it can be concluded that a moderate water deficit promotes root growth better than in a normal water supply condition. Probably this growth is regulated by an ABA/IAA balance which modulates ethylene response.

Повний текст джерелаTwo phytonematicides were researched and developed from fermented crude extracts of wild watermelon (Cucumis africanus) and wild cucumber (Cucumis myriocarpus) fruits for use as alternatives to methyl bromide in managing root-knot (Meloidogyne species) nematodes in tomato (Solanum lycopersicum) production. Fruits of C. africanus contain cucurbitacin B (C32H48O8), while those of C. myriocarpus contain cucurbitacin A, which comprises cucumin (C27H40O9) and leptodermin (C27H38O8). Phytonematicides from C. africanus and C. myriocarpus fruits are referred to as nemafric-B and nemarioc-A, respectively. The two phytonematicides, due to their origin from plant species with allelochemicals, have high potential of being phytotoxic to crops. The use of the Curve-fitting Allelochemical Response Dosage (CARD) computer-based model assisted in the establishment of concentrations which were stimulatory to growth of tomato (Solanum lycopersicum) plants, while exhibiting nematoxic properties to Meloidogyne species. The two phytonematicides were developed from crude extracts of fruits dried at 52˚C in air-forced ovens and ground in a Wiley mill through 1-mm-opening sieves. However, equipment for drying and grinding fruits would not be accessible to smallholder farmers who wished to prepare their own products on-farm. The objective of this study therefore, was to determine whether nemafric-BL and nemarioc-AL produced from fresh fruit of the two Cucumis species would be suitable for use (i.e. non phytotoxic) in tomato production for managing population densities of M. incognita race 2. In order to distinguish the products of fresh (F) fruits from those of dried (D) fruits, they were code-named nemafricF-BL or nemariocF-BL and nemafricD-BL or nemariocD AL, respectively, where G and L denoted granular and liquid formulations, respectively. Tomato cv. ‘Floradade’ seedlings were infested with 3 000 eggs and second-stage xv juveniles of M. incognita race 2. An equivalent of 40 g and 80 g dried fruit mass of nemafric-B and nemarioc-A, namely, 284 g and 411 g fresh fruit mass for nemafric-B and nemarioc-A, respectively, were separately fermented using EMROSA effective micro-organisms mixed with 16 L chlorine-free tapwater in 20 L container for 14 days at ± 25˚C, allowing pH to gradually decline to ± 3.7. Separate experiments for each product run concurrently. Treatments, namely, 0, 2, 4, 8, 16, 32 and 64% concentrations, where for instance, 2% = 20 ml/1000 ml x 100, were arranged in a randomised complete block design, with 10 replications. Blocking in the greenhouse was done for wind direction which was regularly erected by fans for cooling down the greenhouse. At 56 days after weekly application of each treatment, flower number, fruit number, dry shoot mass, dry root mass, dry fruit mass, plant height, stem diameter and nematode numbers were each subjected to analysis of variance. Nematode data were, prior to analysis, transformed using log10(x + 1), but untransformed data were reported. Using the sum of squares, nemafric-BL and nemarioc-AL treatments affected dry root mass, dry shoot mass, flowers number, fruit number, plant height and stem diameter. Nemafric-BL contributed 67%, 78%, 58%, 43%, 60% and 26%, while nemarioc-AL contributed 71%, 61%, 19%, 35%, 34% and 24% to total treatment variation of the six respective variables. Plant variables with significant (P ≤ 0.05) treatment effects were further subjected to the CARD model to generate seven biological indices, with three distinct phases, namely, stimulation, neutral and inhibition phases. Using the quantified stimulation phase, the mean concentration stimulation range (MCSR) was computed for each variable using two biological indices, namely, threshold stimulation point (Dm) and saturation point (Rh). The CARD model explained 98%, 99%, 98% and 98% of the quadratic models of dry root mass, dry shoot mass, plant height and stem diameter, xvi respectively, against increasing concentrations of nemarioc-AL. Similarly, the CARD model explained 99%, 96%, 84% and 93% of total treatment variation in the respective plant variables. The integrated MCSR [MSCR = Dm + (Rh/2)] for nemafric-BL on tomato plants was 7%, while that for nemarioc-AL was 4%. In the CARD model, the overall sensitivities (∑k) of tomato plants exposed to nemafric-BL and nemarioc-AL were 3 units and 5 units, respectively. Tomato plants were therefore, less sensitive to nemarioc-AL since it had higher ∑k value than nemafric-BL. At 4% nemarioc-AL and at 7% nemafric-BL, the two phytonematicides were each highly suppressive to population densities of M. incognita race 2. In conclusion, on the basis of non-phytotoxicity of the computed MCSR values and their suppressive effects on population densities of M. incognita race 2, the smallholder farmers could produce nemafric-BL and nemarioc-AL phytonematicides on-farm. However, the production of the two products from fresh fruits would not be sustainable since fruits of the two Cucumis species are highly seasonal due to the high incidence of post-harvest decays.

Повний текст джерелаAcidic soils (pH <5.0) represent about 40% of the arable land in the world. In these soils, toxic aluminum becomes soluble and inhibits root growth. Regardless of Al, low pH is, in itself, also toxic, decreasing cell viability and root growth. There is evidence that H+ and Al3+ can affect the cell wall. Reversely, modifications in the wall may determine the degree of tolerance of roots subjected to these stresses. Therefore, we used two approaches to investigate whether possible changes in the cell wall improve growth and cell viability upon exposure to H + and Al³+. In the first approach, roots of plants of the Micro-Tom (MT) cultivar of tomato (Solanum lycopersicum L.), at 2 and 13 days of development, were exposed directly or gradually to low pH. In the second approach, the roots were subjected to hypoosmotic treatment prior to being exposed to pH 4.0 or 4.5 + Al. In 2- and 13-day plants, gradual exposure was achieved by changing the pH over a 12 and 24 h period, respectively. In the hypo-osmotic pre-treatment (priming), plants were transferred from a high osmolarity solution (150 mM) to another with low osmolarity (0.5 mM), at pH 5.8, for 0, 0.5, 1 and 2 h before being exposed to pH 4.0 or 4.5 + Al for 12h. As controls, roots did not receive any osmotic treatment or were maintained continuously at high osmolarity. Growth of roots exposed directly to pH 4.5 was about half that of control roots at pH 5,8 and at pH 4.0 root growth was suppressed. Different from expected, roots exposed gradually to pH 4.5 grew less than those exposed directly to pH 4.5 and at pH 4.0, root growth remained negligible. However, cell viability was maintained in roots exposed gradually to pH 4.0, unlike those exposed directly. Thus, decreased root growth upon exposure to low pH may be a response generated by the plant itself rather than the direct effect of pH. In roots subjected to hypo-osmotic priming prior to exposure to pH 4.0, cell viability was maintained and root growth was up to 38% of that of control roots at pH 5.8, whereas in control roots at pH 4.0, cell death occurred and root growth was insignificant. At pH 4.5 + 5 uM Al, priming did not reverse the inhibition of root growth, suggesting that responses to H+ and Al3+ are different. GPX was involved in responses to both gradual exposure to low pH and to hypo-osmotic treatment prior to low pH, but it was not possible to determine whether this was a consequence or one of the possible causes of these responses. Taken together, the data indicate that possible changes in the cell wall may be involved in improving root growth and cell viability of the root apex during stress.

Повний текст джерелаEndophyten, die nicht zu den Mykorrhizapilzen gehören, können das Innere von Wurzeln ohne sichtbare Krankheitssymptome besiedeln und bilden so mit der Pflanze neutrale oder mutualistische Wechselwirkungen. Diese Pilze, auch als nicht-clavicipetale Endophyten bekannt, haben ein breites Wirtsspektrum von mono- und dikotyledonen Pflanzen und weisen eine hohe Diversität auf. Einige von ihnen fördern Pflanzenwachstum und erhöhen Resistenz und Toleranz gegenüber biotischem und abiotischem Stress. Ausgehenden von diesen möglichen Effekten auf ihre Wirtspflanzen war das Ziel der vorliegenden Arbeit die Isolierung und Charakterisierung neuer pilzlicher Wurzelendophyten der Tomate (Lycopersicon esculentum Mill.) und die Analyse ihres Einflusses auf Pflanzenentwicklung und Pflanzenresistenz, sowie auf Ertrag und Fruchtqualität unter Einbeziehung des Modellendophyten Piriformospora indica. Aus vier verschiedenen Anbaugebieten in Kolumbien konnten 51 neue Pilzstämme von oberflächensterilisierten Tomatenwurzeln isoliert werden. Diese Isolate wurden vorcharakterisiert und 14 potentielle Endophyten bezüglich ihrer Taxonomie, ihrer Besiedlungsmuster und ihres Einfluss auf das Pflanzenwachstum näher untersucht. Sequenzierung der ITS Region des ribosomalen RNA Genclusters und genaue morphologische Charakterisierung zeigten, dass sie zu verschiedenen phylogenetischen Gruppen innerhalb der Ascomycota gehören. Neun Morphotypen ließen sich beschreiben, wobei sechs zu den ‚Dark Septate Endophytes’ (DSEs) gehören, aber nicht mit der bekannten Phialocephala Gruppe verwandt waren. Ausführliche konfokale mikroskopische Untersuchungen ergaben sehr verschiedene Besiedelungsmuster der Wurzelendophyten vom Endringen in die Epidermis bis zum Hyphenwachstum durch den Kortex. Topfexperimente unter Gewächshausbedingungen zeigten dass die Isolate in Abhängigkeit von der Inokulumkonzentration und der Zeit der Besiedlung das Wachstum der Tomaten sehr unterschiedlich beeinflussten. Drei neue Isolate (die beiden unbekannte pilzlichen Endophyten DSE48 und DSE49 und eines identifiziert als Leptodontidium orchidicola) mit neutralen oder positiven Effekten wurden für weitere Versuche ausgewählt. In mehreren Experimenten sollte ihr Einfluss auf das vegetative Wachstum, auf Ertrag und auf Fruchtqualität untersucht werden, sowie ihre Fähigkeit die Auswirkungen des Pathogens Verticillium dahliae auf Tomatenpflanzen zu vermindern. Obwohl wachstumsfördernde Effekte durch alle drei Pilze in jungen Pflanzen beobachtet wurden, waren vegetative Wachstumsparameter nach 22 Wochen der Besiedlung nicht mehr beeinflusst bis auf ein signifikante Erhöhung des Wurzeldurchmessers durch den Endophyten DSE49. L. orchidicola dagegen erhöhte die Biomasse und den Glukosegehalt der Früchte, aber nur zu frühen Ernteterminen und bei einer bestimmten Intensität der Wurzelbesiedelung. Hinsichtlich eines schützenden Effekts, konnten die Endophyten DSE49 und L. orchidicola die Krankheitssymptome, die durch V. dahliae verursacht wurden, vermindern, aber nur bei einem geringen Pathogendruck. Um zu überprüfen, ob der Modellendophyt P. indica in Produktionssytemen eingesetzt werden kann, wurde seine Auswirkungen auf Tomaten untersucht. Ähnlich wie die neuen pilzlichen Isolate, zeigte aber auch er seinen fördernden Einfluss nur auf das frühe vegetative Wachstum. Schützende Effekte gegen V. dahliae konnten ebenfalls nur bei niedrigem Pathogendruck konstant beobachtet werden. Wie L. orchidicola erhöhte P. indica die Biomasse an marktfähigen Tomaten am Anfang des Fruchtansatzes, was nicht zu einem insgesamt höheren Ertrag führte. Ob die beobachteten Effekte auf ein verbesserte Nährstoffversorgung der Pflanze zurückzuführen seien, wurde in Gerste im Vergleich mit dem arbuskulären Mykorrhizapilz Glomus mosseae untersucht. Während der Mykorrhizapilz sowohl Phosphat wie Stickstoffaufnehme der Pflanze erhöhte, konnte dies für P. indica nicht festgestellt werden. Zusammenfassend zeigt diese Arbeit, dass auch aus Wurzeln von Kulturpflanzen viele verschiedene pilzliche Endophyten isoliert werden können, und dass einige von diesen durchaus einen positiven Effekt auf die frühe Pflanzenentwicklung aufweisen. Zumindest für Tomate unter Gewächshausbedingungen führen diese Effekte aber nicht zu einer Erhöhung des Gesamtertrags oder einer nachhaltigen Verbesserung der Fruchtqualität.

Повний текст джерелаThe tomato (Solanum lycopersicum L.) is one of the most important cultivated plants in the world, being one of the main vegetables of economic importance in Brazil. The bacterial wilt is one of the most limiting diseases for the tomato crop and the use of resistant cultivars to Ralstonia spp. is one of the only alternatives to avoid losses caused by this pathogen. However, there are very few studies on the genetic basis of genotypes resistant to the main isolates of Ralstonia spp. The objective of this work was to study the genetic parameters of resistance to bacterial wilt in lines and hybrids used as tomato rootstocks, through complementary approaches that range from the adjustment of the methodologies for artificial induction of the disease, to estimates of the combining abilities and heterosis among lines, aiming to identify promising crosses for the establishment of a rootstock genetic breeding program for resistance to bacterial wilt in tomatoes. Comparing four resistance induction methods, it was verified that the method of injuring roots with cutting object (scalpel) and spraying 5 mL of the bacterial suspension in the clod compared to the other\'s methods evaluated, is easiest to perform, requires less amounts of bacterial suspension and provides good amounts of tomato plants with wilt symptoms, being the most suitable among the methods tested. The heterosis and combining ability of tomato lines for a strain of biovar 2 of Ralstonia solanacearum in greenhouse at seedling stage and in soil naturally infested by Ralstonia spp were estimated. Among the lines evaluated, only the Hawaii 7996 genotype showed acceptable levels of resistance, and it is necessary to find new sources of resistance for the beginning of a breeding program. It was verified that none of the progenies derived from the crosses of this study presented superior resistance to the superior parental. In addition, the importance of the additive effects was verified and, consequently, the crossings of parents with high CGC for the character and the recurrent selection would be the best alternatives in the improvement for resistance to bacterial wilt. Finally, we studied the parents and their hybrids, used as rootstocks under field conditions and in a protected environment aiming the increasing resistance to bacterial wilt caused by Ralstonia spp., and increasing of the yield parameters of a commercial hybrid used as a scion. The influence of the different rootstocks was verified in characters of yield and mass of the fruits and in the development of the scion. Characteristics related to the root system of rootstocks showed heterosis in relation to their parents, with important additive and non-additive effects, showing the performance of the lines and their contribution to the production of superior hybrids. Finally, this study allowed a better understanding of the genetic basis of resistance in tomato genotypes that have potential use as bacterial wilt resistant rootstocks.

Повний текст джерелаSoil acidity is a major factor limiting plant growth worldwide. Aluminum toxicity, which occurs only at low pH, has been extensively studied, whereas low pH stress has received much less attention. Studies on Al3+ and H+ toxicity make the underlying assumption that the effects of these stress factors are additive, and, therefore independent of each other. However, this is most likely not the case and low pH may be a factor which increases susceptibility to further injury by Al3+. There is evidence that low pH causes disruption in cell wall structure of growing cells, which might jeopardize cell wall functionality and integrity. It is likely that turgor pressure plays an important role in cell wall stress caused by low pH. The apoplastic metabolism of reactive oxygen species (ROS) can modulate cell wall extensibility by making or breaking bonds within and between cell wall polysaccharides. A major question is whether, similarly to yeast, plant cells have a cell wall integrity signaling and response system. Growing root hairs are sensitive to low pH and hypo-osmotic stress and are potentially good experimental systems for such investigations. The objectives of this study were: a) Optimize an experimental system to examine tomato (Solanum lycopersicum L. cv Micro-Tom) root hairs; b) Examine the response of root hairs to low pH and hypo-osmotic stress; c) Examine the role of oxidative modulation of the cell wall in these responses; and d) Evaluate the response of different hormonal mutants of Micro-Tom to these stress factors. Root hair elongation rates (µm.min-1) and the frequency of cell bursting were the major experimental parameters which were evaluated. Both low pH and, more markedly, hypo-osmotic stress caused significant reductions in elongation rates and the bursting of root hair tips. In a response curve to varying osmolarities of the external medium, root hair elongation rates increased with decreasing osmolarities until a threshold was reached and elongation rates decreased drastically and the bursting of root hairs began to be observed. Interactions between low pH and hypo-osmolarity were observed. The use of the inhibitor diphenylene iodonium (DPI) did not provide evidence for the involvement of plasma membrane NADPH in the response of root hairs to low pH and hypo-osmotic shock. However, a role for cell wall peroxidases was provided by use of the inhibitor salicylhydroxamic acid (SHAM). Root hairs of the hormonal mutants dgt (low sensitivity to auxin) and epi (ethylene super producer), but not not (deficient in abscisic acid), displayed a more effective response to hypo-osmotic shock than Micro-Tom, by decreasing elongation rates and cell bursting to a greater degree. This study provides strong evidence to suggest that root hairs have a cell wall integrity response system and that root hairs are potentially good cell model systems for such research

The tomato crop is attacked by a high range of pathogens, and among them are the nematodes of genera Meloidogyne. Among the various methods of controlling these pathogens, biological control has stood out on the world stage. The nematode survey is a necessary measure to plan and achieve the appropriate management. This study aimed to make a nematode survey in different producing areas of tomatoes in the vicinity of Goiânia-GO, evaluate the efficiency of different biological products in reducing Meloidogyne incognita population in the tomato crop, and to evaluate the most effective dose of a product based on Bacillus and Trichoderma. In this study nematode survey was performed in the tomato-producing areas of the surroundings of Goiânia-GO for a better understanding of the genera occurring in this crop. Also, four experiments were conducted: two to evaluate different doses of the biological product NemOutTM (Bacillus spp. and Trichoderma longibrachiatum) and two to evaluate different commercial biological products in reducing Meloidogyne incognita population and promoting tomato growth. The survey was conducted on ten tomato areas, in two consecutive years. Soil and root samples were collected and performed the extraction of nematodes and the identification of genera. The experiments were conducted in a greenhouse at the Universidade Federal de Goiás, in polyethylene pots (5L) containing sterilized substrate 1: 1 (soil + sand) in two periods, from March to May and October to December of 2014. Inoculation was made with 2,000 eggs and J2 of M. incognita. At 45 and 65 days after inoculation (DAI) the variables plant height, fresh weight shoots, fresh weight of root, galls index and egg mass index, nematode density and reproduction factor (RF), were evaluated. Producing tomato areas around Goiania-GO showed presence of genres Meloidogyne sp., Pratylenchus sp., Helicotylenchus sp., Criconemella sp. and Tylenchus sp. There was a greater abundance and dominance of Helicotylenchus sp. and Meloidogyne sp. on tomato areas studied. The use of crop rotation and fallow were effective in reducing the population of the genera found in the study area. Saturations of higher bases were positively correlated with the population density of Helicotylenchus sp., Pratylenchus sp. and Criconemella spp. and negative with the population density of Meloidogyne sp. At 45 DAI, in the first experiment, increasing doses of NemOutTM reduced the nematode population density and de reproduction factor (RF) linearly. In tested conditions the biological products NemOutTM, Nemat®, Paecilomyces JCO®, Serenade® and isolated P. chlamydosporia Pc-10 did not affect the development of tomato plants. The Serenade® product reduced index of galls and egg mass equaling the chemical in some cases.
A cultura do tomate é atacada por uma elevada gama de patógenos, e entre eles estão os nematoides do gênero Meloidogyne. Entre os vários métodos de controle desses patógenos, o controle biológico vem se destacando no cenário mundial. Fazer um levantamento dos nematoides presentes na área de produção é uma medida necessária para se planejar e realizar o manejo adequado. Este trabalho teve como objetivo fazer um levantamento de nematoides em diferentes áreas produtoras de tomate no entorno de Goiânia-GO, avaliar a eficiência de diferentes produtos biológicos na redução da população de Meloidogyne incognita na cultura do tomate, além de avaliar a dose mais eficaz de um produto a base de Bacillus e Trichoderma. Neste trabalho foi realizado um levantamento em áreas produtoras de tomate da região do entorno de Goiânia-GO, para um melhor conhecimento dos gêneros de nematoides presentes nessa cultura. Foram realizados também quatro experimentos, dois para avaliar diferentes dosagens do produto biológico NemOutTM (Bacillus spp. e Trichoderma longibrachiatum) e dois para avaliar diferentes produtos biológicos comerciais na redução da população de Meloidogyne incognita e na promoção do crescimento do tomateiro. O levantamento foi realizado em dez áreas produtoras de tomate, em dois anos consecutivos. Foram coletadas amostras de solo e raiz. Foram realizadas as extrações dos nematoides e a identificação dos gêneros. Os experimentos foram conduzidos em casa de vegetação na Universidade Federal de Goiás, em vasos de polietileno (5L), contendo substrato esterilizado na proporção de 1:1 (solo + areia), em dois períodos, de Março a Maio e de Outubro a Dezembro de 2014. Foram inoculados 2000 ovos e J2 de M. incognita. As avaliações foram realizadas aos 45 e 65 dias após a inoculação (DAI). Foram avaliadas as variáveis altura da planta, massa fresca da parte aérea, massa fresca da raiz, índice de galhas e massas de ovos, densidade populacional do nematoide e fator de reprodução (FR). Áreas produtoras de tomate no entorno de Goiânia-GO apresentaram presença dos gêneros Meloidogyne sp., Pratylenchus sp., Helicotylenchus sp., Criconemella sp. e Tylenchus sp. Houve maior abundância e dominância de Helicotylenchus sp. e Meloidogyne sp. nas áreas de tomate estudadas. A utilização de rotação de culturas e do pousio se mostraram eficientes na redução da população dos gêneros encontrados nas áreas estudadas. Saturações de bases mais altas apresentaram correlação positiva com a densidade populacional de Helicotylenchus sp., Pratylenchus sp. e Criconemella sp. e negativa com a densidade populacional de Meloidogyne sp. Na avaliação aos 45 DAI, do primeiro experimento, doses crescentes do produto NemOutTM reduziram a densidade populacional e o fator de reprodução de M. incognita linearmente. Nas condições testadas os produtos biológicos NemOutTM, Nemat®, Paecilomyces JCO®, Serenade® e o isolado P. chlamydosporia Pc-10 não afetaram o desenvolvimento das plantas de tomate. O produto Serenade® reduziu o índice de galhas e o índice de massas de ovos se igualando ao produto químico em alguns casos.
