Resumo:

The problem of the steady food supply to the population is becoming particularly pressing in the face of a projected decrease in the specific area of agricultural land per resident. In an effort to increase crop yields, agriculture depends mainly on chemical plant protection agents (PPAs), which produce strong negative effects. The research activities need to be concentrated on developing the alternative plant protection technologies that will ensure a sufficient crop yield increase. Based on statistical data of the Food and Agriculture Organization of the United Nations (FAO) and studies and analytical reviews on protection of agricultural crops, the present work describes current market trends in the global crop protection industry: the volume and dynamics of the global PPA market, the regional distribution of this market, and the consolidation of key producers. Recent years have seen a decrease in the number of new chemical PPAs entering the market due to the greater research effort devoted to novel crop protection technologies, in particular genetically modified crops (GM crops), biological PPAs, and other alternative technologies, which are being developed and put on the market in response to increasingly stringent regulations in agrochemistry and ecology. Recommendations are made to producers of agrochemicals that will allow them to remain competitive and contribute to satisfaction of the growing demand for agricultural products

RNAi technology is a versatile, effective, safe, and eco-friendly alternative for crop protection. There is plenty of evidence of its use through host-induced gene silencing (HIGS) and emerging evidence that spray-induced gene silencing (SIGS) techniques can work as well to control viruses, bacteria, fungi, insects, and nematodes. For SIGS, its most significant challenge is achieving stability and avoiding premature degradation of RNAi in the environment or during its absorption by the target organism. One alternative is encapsulation in liposomes, virus-like particles, polyplex nanoparticles, and bioclay, which can be obtained through the recombinant production of RNAi in vectors, transgenesis, and micro/nanoencapsulation. The materials must be safe, biodegradable, and stable in multiple chemical environments, favoring the controlled release of RNAi. Most of the current research on encapsulated RNAi focuses primarily on oral delivery to control insects by silencing essential genes. The regulation of RNAi technology focuses on risk assessment using different approaches; however, this technology has positive economic, environmental, and human health implications for its use in agriculture. The emergence of alternatives combining RNAi gene silencing with the induction of resistance in crops by elicitation and metabolic control is expected, as well as multiple silencing and biotechnological optimization of its large-scale production.

My remarks today will be largely devoted to assessing some of the effects of the Food Quality Protection Act of 1996. As introduced, the act had wide support among grower groups, the food industry, and the pesticide industry. Voting on the bill was unanimous in both House and Senate, and action was completed in 1 wk. The legislation was signed by the President on August 3, 1996. President Clinton wanted to be seen as a strong advocate of children's health. The Republican Congress wanted to show that it was pro-environment.

Resumo:

Chemotaxis in Agrobacierium tumefaciens was studied. Several plant derived monocyclic phenolic compounds were analysed for their ability to act as chemoattractants for A. tumefaciens C58C (^1) and as inducers of the Ti-plasmid virulence operons. The results divided the phenolics into 4 groups. A strong correlation between vir- inducing ability and Ti-plasmid requirement for chemo taxis was established and chemical structure rules for vir induction and chemo taxis are outlined. Furthermore, virA and virG were found to be the Ti-plasmid virulence genes required for chemo taxis towards the monocyclic phenolic compound acetosyringone. Chemotaxis towards both monocotyledonous and dicotyledonous plant extracts was analysed. Undiluted shoot and root extracts from both sources elicited a response from both Ti-plasmid harbouring and cured A. tumefaciens C58C(^1) However, when diluted extracts of Wheat and Kalanchoe shoot homogenate were analysed, a distinct enhancement of chemotaxis was conferred by the Ti-plasmid, suggesting that recognition of, and attraction towards, susceptible plants is not the step blocked in monocot transformation. Analysis of cell wall material revealed that native cell wall components are not required for chemotaxis of A. tumefaciens C58C (^1) towards plant extracts. Results obtained on chemotaxis along with current knowledge of vir- induction allowed the development of a novel idea involving Agrobacterium as a biocontrol agent. A chitinase gene from Serratia marcescens was manipulated such that its promotor was removed. The promotorless cassette was linked to the virB pro-motor from an octopine Ti-plasmid and the construct introduced into Agrobacterium harbouring virA and virG. The potential benefit of this biocontrol system with respect to other existing biocontrol systems is that expression of the pesticidal gene is regulated by components of wound exudate and therefore is a conservative process, pesticide being produced only when a plant is wounded, at a time when it is most susceptible to attack by plant pathogens, and then exclusively in the microrhizosphere around the wound site.

Els fongs patògens de plantes causen importants pèrdues en les collites, posant en perill la seguretat i qualitat alimentària. Els pèptids antimicrobians (AMPs) mostren una activitat lítica potent i duradora específicament enfront de microorganismes, de manera que tenen un gran potencial com a nous fungicides naturals per al control dels fongs patògens. La seva explotació requereix de sistemes de producció ràpids, eficaços, econòmics i segurs. El principal objectiu d’aquest treball era desenvolupar sistemes de producció sostenibles de AMPs, i la seva caracterització en el control d’infeccions fúngiques per avançar en la seva aplicació en l’agricultura. Les proteïnes antifúngiques (AFPs) secretades per fongs filamentosos són un grup de AMPs rics en cisteïnes, molt estables, actius específicament enfront de fongs. En aquest estudi vam demostrar que les plantes de Nicotiana bentamiana són una excel·lent biofactoria de AFPs mitjançant expressió transitòria usant un nou vector derivat del virus de mosaic del tabac. Utilitzant aquest sistema de producció en plantes, hem produït eficientment dues AFPs molt actives enfront de fongs fitopatògens, la AfpA de Penicillium expansum i la AfpB de Penicillium digitatum. Hem descobert que el compartiment subcel·lular on s’acumulen les AFPs té un impacte important en la producció obtinguda, probablement perquè la seva compartimentació evita la toxicitat cap a les cèl·lules vegetals. Els valors més alts es van obtenir quan les proteïnes es van acumular en els vacúols, aconseguint fins 0,170 mg / g de fulla en el cas de la proteïna més activa AfpA i fins a vuit vegades més per a la AfpB (1,2 mg / g de fulla). També vam demostrar que els extractes crus de plantes que contenen AFP són actius enfront a fongs, sense necessitat de purificar les proteïnes reduint considerablement el processament del material vegetal i els costos de producció. Per tant, el sistema desenvolupat és eficient per a la producció de AFPs, i també és econòmic i segur ja que es basa en plantes. A més, hem desenvolupat un sistema alternatiu per a la producció del pèptid antifúngic PAF102 que prèviament no s’havia pogut produir biotecnològicament. Aquest sistema es basa en acumular el pèptid en les gotes lipídiques (LDs) mitjançant la fusió a una proteïna oleosina de plantes. Mitjançant aquesta estratègia, hem produït PAF102 en llavors d’arròs en quantitats de 20 mg per gram de llavor. No obstant això, la producció en llavors és lenta i per accelerar el procés hem transferit la tecnologia de la fusió a oleosinas de plantes al sistema de Pichia pastoris. Usant aquest nou sistema hem obtingut rendiments comercialment rellevants amb produccions de 180 mg / l de cultiu en només 4 dies. L’acumulació de PAF102 a les LDs de les llavors d’arròs i del llevat facilita enormement la seva extracció per simple flotació en solucions denses, permetent la recuperació de pèptid biològicament actiu. Finalment, hem demostrat que tant AfpA i AfpB produïdes en plantes, com els extractes de plantes enriquits en aquestes proteines, són eficaços en la prevenció d’infeccions fúngiques en cultius econòmicament rellevants, com ara la podridura grisa causada per Botrytis cinerea en fulles i fruits de tomàquet, la piriculariosis causada per Magnaporthe oryzae, o les infeccions de les llavors d’arròs per Fusarium proliferatum. Els nostres resultats proporcionen un sistema de producció sostenible de AFPs i demostren la seva eficàcia en la protecció de les plantes contra les infeccions fúngiques, donant ferm suport per al seu ús com a “fungicides verds” eficaços i respectuosos amb el medi ambient en la protecció de cultius, mentres són al canmp o durant el periode postcollita.

Los valores más altos se obtuvieron cuando las proteínas se acumularon en las vacuolas, alcanzando hasta 0,170 mg/g de hoja en el caso de la proteína más activa AfpA y hasta ocho veces más para la AfpB (1,2 mg/g de hoja). También demostramos que los extractos crudos de plantas que contienen AFP son activos frente a hongos, sin necesidad de purificar las proteínas reduciendo considerablemente el procesamiento del material vegetal y los costes de producción. Por lo tanto, el sistema desarrollado es eficiente para la producción de AFPs, y también es económico y seguro ya que se basa en plantas. Además, hemos desarrollado un sistema alternativo para la producción del péptido antifúngico PAF102 que previament no había podido producirse biotecnológicamente. Este sistema se basa en acumular el péptido en las gotas lipídicas (LDs) mediante la fusión a una proteína oleosina de plantas. Mediante esta estrategia, hemos producido PAF102 en semillas de arroz en cantidades de 20 mg por gramo de semilla. Sin embargo, la producción en semillas es lenta y para acelerar el proceso hemos transferido la tecnología de la fusión a oleosinas de plantas al sistema de Pichia pastoris. Usando este nuevo sistema hemos obtenido rendimientos comercialmente relevantes con producciones de 180 mg/l de cultivo en sólo 4 días. La acumulación de PAF102 en las LDs de las semillas de arroz y de la levadura facilita enormemente su extracción por simple flotación en soluciones densas, permitiendo la recuperación de péptido activo frente a hongos patógenos. Finalmente, hemos demostrado que tanto AfpA y AfpB producidas en plantas, como los extractos de plantas enriquecidos estas proteinas, son eficaces en la prevención de infecciones fúngicas en cultivos económicamente relevantes, tales como la podredumbre gris causada por Botrytis cinerea en hojas y frutos de tomate, el quemado del arroz causado por Magnaporthe oryzae, o las infecciones de las semillas de arroz por Fusarium proliferatum. Nuestros resultados proporcionan un sistema de producción sostenible de AFPs y demuestran su eficacia en la protección de las plantas contra las infecciones fúngicas, apoyando firmemente su uso como "fungicidas verdes" eficaces y respetuosos con el medio ambiente en la protección de cultivos y postcosecha.
Plant diseases caused by pathogenic fungi are responsible of important crop losses endangering food security and safety. Antimicrobial peptides (AMPs), exhibiting potent and durable lytic activity specifically against microorganisms, have a great potential as novel natural fungicides for the control of pathogenic fungi. However, viable exploitation of AMPs requires fast, cost-efficient, and safe production systems. The main goal of this work was to develop a sustainable platform for the production of bioactive AMPs, and to characterize them in the control of fungal infections in plants to advance in their application in agriculture. Antifungal proteins (AFPs) secreted by filamentous fungi are a group of highly stable cysteine-rich AMPs that specifically target fungal cells. In this study, we demonstrate that Nicotiana benthamiana plants are an excellent biofactory for producing AFPs through transient expression using a new vector derived from the tobacco mosaic virus. Using this plant-based production system we efficiently produced two different bioactive AFPs, the Penicillium expansum AfpA and Penicillium digitatum AfpB. We found that the subcellular compartment where AFPs are accumulated has an important impact on protein yield, probably avoiding toxicity towards plant cells. The highest yields were achieved when targeting AFPs to vacuoles, reaching up to 0.170 mg/g of fresh leaves of the highly active AfpA and eight times more of AfpB (1.2 mg/g of leaf). We also show that plant crude extracts containing AFPs are fully active against plant pathogens without requiring further protein purification, thus reducing significantly downstream processing. Therefore, the developed system is efficient for the production of AFPs, and also it is economic and safe since it is based on plants. We also developed an alternative system for the production of the linear PAF102 antifungal peptide that was recalcitrant to be produced in biological systems. This system is based on targeting the peptide to lipid droplets (LDs) through the fusion to a plant oleosin protein. Using this oleosin fusion technology, we produced PAF102 in rice seed LDs, reaching moderate yields of about 20 mg of peptide per gram of grain. Production on rice seeds is long process in order to speed the process, we successfully transferred the plant oleosin fusion technology to the Pichia pastoris system. We produced commercially relevant yields of PAF102 in these yeast LDs, reaching values of 180 mg/l of culture in only 4 days. The accumulation of PAF102 in the LDs of rice seeds and yeast facilitated its downstream extraction and recovery by simple flotation on dense solutions, with the recovered PAF102 being biologically active against pathogenic fungi. Finally, we demonstrate that in planta produced AfpA and AfpB, either purified protein or protein extracts enriched with these two proteins, are efficient in controlling important fungal diseases on economically relevant crops, including Botrytis gray mold disease in tomato leaves and fruits, blast disease in rice plants and Fusarium proliferatum infection in rice seeds. Our results provide a sustainable production system of AFPs, and evidence their efficacy on protecting plants from fungal infection, strongly supporting the use of AFPs as environmental friendly and effective “green fungicides” in crop and postharvest protection.

Resumo:

This study presents the theoretical and experimental results of natural ventilation rates induced by stack, wind and the combination of both stack and wind effects for a typical crop protection structure suitable for the tropics. The structure consists of simple structural frame, transparent roofing and insect screen side walls. It was found the relative importance of the stack and wind effects is dependent on the ratio between wind speed and the square root of the inside-outside temperature difference (u/AT°.5). In this study, the wind effect dominates over the stack effect when the ratio u/AT" becomes greater than 0.5. Ventilation rate induced by the stack effect was found to increase with increasing temperature difference between inside and outside of the crop protection structure according to a power law, with an index of 0.5. The wind effect ventilation rate was found to increase linearly with increasing outside wind speed measured at eaves level. In addition, the combination of the stack and wind effects could be represented as the vectorial sum of two the independent effects (40sw = (43)k2 + (1)„,nd21 0.5). However, the result of the wind effect in the combined effects was insignificant when the ratio of ventilator opening to the total wall area is higher than 20 %. Different methods have been used to determine the natural ventilation rates. The dynamic tracer gas was used as the control; direct airspeed measurement, energy balance and neutral plane methods were used to quantify ventilation induced by the stack effect. Pressure field measurements were used to quantify ventilation by wind effect. In addition, the dynamic tracer gas, energy balance, and stack and wind methods were used to quantify ventilation induced by the combined effects. However, these methods have their constraints and limitations because of statistically significant differences in the comparison between the methods. The tracer gas method was found very difficult to use in the highly porous structure. In addition, the ventilation rate measured by this method was 30-40 % less than the other methods. The energy balance method has the advantage that it estimates many important climatic and crop parameters, however, the errors were found to be the highest. The neutral plane method was suitable for measuring ventilation induced by stack effect, the simplest method, requiring only the measurement of the inside and outside temperatures. The direct airspeed measurement method was much easier to handle and the result was comparable to other methods suitable for determining the ventilation induced by the wind effect. The physical properties of the covering materials, namely light transmission, coefficient of discharge and airflow characteristics were also determined in this study. It was found that the light transmissions of transparent polythene film and insect screens were close to each other. The coefficient of discharge and light transmission were dominant parameters in the ventilation rate calculation. It was found that when air flows through a screen, the pressure drop increases linearly with the square of approach airspeed. Airflow distributions inside the crop protection structure induced by the stack and wind effects are also presented in this study. Finally, this study presents information on natural ventilation for tropical greenhouses that was not previously available.

In agricultural research, plant genetic resources (PGR) are “non-traditional infrastructural resources”, which may generate higher social value and positive externalities if they are managed in an openly accessible manner. The privatisation of crop biodiversity is based on the assumption that the internalisation of these externalities is the panacea to fostering private research investment. However, if the domestic plant breeding and biotechnology capacity is limited, the above normative approach may fall short of expectations because the social costs of establishing or strengthening exclusion rights are higher than their social benefits. The International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) is the only international agreement whose normative approach reflects in part this economic reality. However, its constructively ambiguous intellectual property rights-related provisions do not effectively fence off crop biodiversity from private appropriation. Besides, the desire of most countries not to prejudice the negotiation of an international access and benefit sharing regime under the UN Convention of Biological Diversity may prevent the extension of the ITPGRFA’s “commons” management principles to a larger number of essential food crops. The scope of this study, which focuses on PGR and agricultural innovation, derives from the paramount importance that both the design and allocation of rights in these areas might have for global food security. The innovation system perspective shows that social and economic development depends on the institutional context in which technological change occurs. Finally, the study of the transition between property regimes shows that the global reform of the institutional arrangements, which govern the present and future allocation of wealth from agriculture, is insufficient to achieve international equity so as to meet the target of reducing the proportion of people who suffer from hunger in accordance with goal 1 of the Millennium Development Goals.

Resumo:

An Enzyme-Linked Immunosorbent Assay (ELISA) was developed which detected slug antigens in postmortem gut analysis of carabid beetles. The ELISA was used to identify beetles which fed on slugs in three fields of oilseed rape and winter wheat in the Tyne valley, Northumberland. Generalist species such as Harpalus rufipes, Pterostichus melanarius, Pterostichus nladidus, Anlara silnilata and Nebria brevicollis fed on slugs in the field. Molluscan specialists such as Carabus violaceus and Cychrus caraboides also fed on slugs in the field. Laboratory studies indicated that many large and medium sized carabids were able to predate small slugs. Some beetle species did not eat slugs but exposure to the beetles increased slug mortality. Therefore, postmortem investigations may underestimate the impact that carabids exert on slugs as they do not measure the number of slugs killed. Slug mucus affected the locomotory activity of generalist and specialist beetle species. Beetles foraged longer, covered greater distances, made more turns, walked slower and spent more time stationary on soil covered in slug mucus compared to control areas. Abax parallelepipedus, P.melanarius, Pterostichus niger and H.rufipes all reduced slug damage to a chinese cabbage crop in a miniplot experiment compared with unprotected plots. However, these differences were not significant. A.parallelepipedus was most effective at reducing slug damage to the chinese cabbage but was rare in arable land. H.rufipes was least effective at reducing slug damage but was abundant in arable land in both years of the study. A high proportion of H.rufipes beetles fed on slugs in the field. None of these four species occurred at densities in the field which reduced slug damage in the miniplot experiment.

Resumo:

Chilling-sensitivity is an important agricultural problem in both the U.S. and Israel. Most research attention has focused so far on herbaceous crop plants, even though the problem is also acute in the fruit tree industry. Under BARD funding we made substantial progress in identifying the mechanisms involved in the disruption of photosynthesis following a chill in mango. Our investigation with fruit trees has been substantially accelerated by drawing on our knowledge and experience with herbaceous crops. The four original research objectives, focused or discovering the underlying mechanisms of chill-induced inhibition of photosynthesis in fruit trees, and the main achievements are listed below. [1] Separating stomatal from non-stomatal components of chilling on photosynthesis in fruit trees. We found evidence that the dark chill-induced inhibition of photosynthesis in mango was E combination of both stomatal and mesophyll components. [2] Differentiating photo damage from light-induced photo protection of photosystem II (PSII). Dark chilling exacerbate high light photoinhibition, as a result of primary inhibition in the carbor reduction cycle. Nevertheless, in Israeli orchards we observed chronic photoinhibition of PSII photochemistry in the winter. This photo damage was reversible over a few days if sunlight was attenuated with filters or night temperature rose. Practical implications of this finding deserve further investment. Additional achievement was the development of a new biophysical tool to study macro-structural changes of LHCII particles in intact, attached leaves. [3] Determine the role of oxidative stress in the dark-chilling-induced inhibition, with emphasis on oxygen radical scavenging, lipid peroxidation and redox-controlled carbon-cycle enzymes. We found an increase in lipid peroxidation following a dark chill, and partial protective effects or an antioxidant. However, the photoinhibition observed in mango orchards in Israel during the winter did not appear to be a general oxidative stress. [4] Investigate whether chilling interferes with the diurnal and circadian rhythm of gene expression of key photosynthetic proteins as has been shown for chilling-sensitive crop plants. The results indicated that most of the circadian rhythm in photosynthesis was due to reduced lea: internal CO2 concentrations during the subjective night, as a result of rhythmic stomatal closure Chilling-induced interference with circadian timing in mango, does not play the central role in chilling inhibition of photosynthesis that has previously been demonstrated in certain chilling sensitive herbaceous plants. Practical implications of the research achievements are feasible, but require few more years of research.
