A type of dwarfism found in crosses involving the wheat (Triticum aestivum L.) cultivar Webster and a stem rust (Puccinia graminis tritici Erik. &Henn.) susceptible line, LMPG, proved to be due to a dominant gene from cv. Webster and a recessive gene from LMPG. The dominant gene is closely linked to the gene Sr30, which conditions stem rust resistance in cv. Webster and is on chromosome 5D. The dwarf plants have short, dark green, stiff leaves and rarely develop more than two leaves before dying.Key words: dwarfism, Triticum aestivum, Puccinia graminis tritici, stem rust.

Resumo:

The inheritance of stem rust (Puccinia graminis f. sp. tritici Eriks. and Henn.) resistance was studied in 'K253', a hexaploid wheat (Triticum aestivum L.) with resistance derived from a tetraploid wheat (T. turgidum L.). The studies indicated that 'K253' carries one dominant gene for good resistance to races 29 and 56 (probably Sr9e) and one recessive gene for moderate resistance to race 15B-1. In addition, some plants apparently carry a recessive gene for moderate resistance to race 56. Four different types of hexaploid near-isogenic lines were produced. One carried Sr9e and another the gene for moderate resistance to race 15B-1. Two carried genes that had not been identified in the genetic studies, including one that was apparently not derived from K253.Key words: stem rust resistance, Puccinia graminis tritici, wheat, Triticum aestivum, Triticum turgidum.

Twelve lines of wheat (Triticum aestivum L.) were originally identified as having a segment of Agropyron elongatum chromatin carrying a gene for resistance to leaf rust (Puccinia recondita tritici) transferred to wheat chromosome 7D. By studying the chromosome pairing of one of these lines, transfer no. 12, with telosomes 7AL, 7AS, 7BL, 7BS, 7DL, 7DS, and 7AgS, it was determined that the Agropyron chromatin was carried on the long arm of wheat chromosome 7A rather than 7D. This determination was confirmed by acetocarmine–N-banding. Key words: Triticum aestivum, Agropyron elongatum, transfer lines, Puccinia recondita tritici, telosomic analysis.

Common wheat (Triticum aestivum), one of the world’s most consumed cereal grains, is known for its uses in baking and cooking in addition to its medicinal uses. As this plant’s medical benefits are enormous and scattered, this narrative review was aimed at describing the pharmacological activities, phytochemistry, and the nutritional values of Triticum aestivum. It is a good source of dietary fiber, resistant starch, phenolic acids, alkylresorcinols, lignans, and diverse antioxidant compounds such as carotenoids, tocopherols and tocotrienols. These constituents provide Triticum aestivum with a wide range of pharmacological properties, including anticancer, antimicrobial, antidiabetic, hypolipemic, antioxidant, laxative, and moisturizing effects. This review summarized the established benefits of wheat in human health, the mode of action, and different clinical, in vitro and in vivo studies for different varieties and cultivars. This review also gives an insight for future research into the better use of this plant as a functional food. More clinical trials, in vivo and in vitro studies are warranted to broaden the knowledge about the effect of Triticum aestivum on nutrition-related diseases prevention, and physical and mental well-being sustenance.

Resumo:

Leaf rust caused by Puccinia triticina is the most important disease among the three rusts of wheat in Bangladesh. The disease occurs in all wheat growing areas of the country with varying degrees of severity. Stem rust caused by P. graminis f.sp. tritici was last observed during the mid 1980s, while yellow rust caused by P. striiformis f.sp. tritici occurs occasionally in the north-western region, where a relatively cooler climate prevails during the winter months. None of the rusts has yet reached an epidemic level, but damaging epidemics may occur in future, particularly if a virulent race develops or is introduced. The genes conferring rust resistance in the breeding lines and wheat varieties released in Bangladesh were investigated at CIMMYT-Mexico and DWR-India. The resistance genes Lr1, Lr3, Lr10, Lr13, Lr23 and Lr26, Sr2, Sr5, Sr7b, Sr8b, Sr9b, Sr11 and Sr31; and Yr2KS and Yr9 were found. An adult plant slow rusting resistance gene Lr34 was also identified in some of the breeding lines and varieties based on the presence of clear leaf tip necrosis under field conditions. Considering the possible risk of migration of the devastating Ug99 race of stem rust into the Indo-Pak subcontinent, the Bangladeshi wheat lines and cultivars are being regularly sent to KARI in Kenya for testing their resistance against this race. The resistant lines have been included in multi-location yield trials and multiplied for future use in order to mitigate the threat of Ug99. The resistant lines have also been included in crossing schemes to develop genetic diversity of rust resistance.

Rhizosphere fungi are strongly associated with plant growth and health by providing nutrients and antagonizing pathogens. Commercially, fungus has multipurpose applications in several sectors including beverages, food items and in medicines. Current study aimed to reveal the core fungal community structure of the two leading cereal crops that are Zea mays L. and Triticum aestivum L. The rhizosphere fungal community was explored via morphology, biochemistry and internal transcribe spacer (ITS) metagenomics. On the basis of morphology, the retrieved fungal strains were imprecisely classified into Ascomycota and Zygomycota. The species including Yeast, Botyritis californica, Rhizopus stolonifer, Alternaria tenuissima, Aspergillus terreus, Aspergillus flavus, Aspergillus nidulans, Aspergillus niger and Microsporum canis were identified on the basis of macroscopy and microscope. Moreover, the biochemical characterization depicted the role of fungi in promotion of plant growth. Majority of the isolates depicted catalase activity, indole production, phosphate solubilization, ammonia production, nitrogenase activity and urease activity. Metagenomics using amplicon sequencing of ITS region revealed the presence of 805 Operational Taxonomic Units (OTUs) with 647 OTUs in Zea mays and 620 OTUs in Triticum aestivum. The fungal phyla found in the rhizosphere of Zea mays L. and Triticum aestivum L. were Ascomycota, Basidiomycota, Zygomycota, Chytridiomycota, Incertae sedis fungi. Ascomycota accounted for 93% and 95% of classified fungi in rhizosphere of Zea mays L. and Triticum aestivum L. respectively. The dominant species found in the rhizosphere soil of Zea mays were Gibberella intricans, Curvularia lunata, Lepidosphaeria nicotiae, Edenia gomezpompae and Myrothecium verrucaria.

The main goal of hybrid wheat breeding is the identification of parents with high specific combining ability for grain yield and other agronomic traits. This kind of data facilitate the development of hybrid combinations with high level of heterosis in first filial generation (F1 generation). The use of species from the hexaploid wheat group (e.g. Triticum spelta L. Triticum compactum HOST...) is representing an opportunity for the increase of heterosis level in the germplasm of common wheat (Triticum aestivum L.). The study of combining ability and heterosis effect in hexaploid wheat group was carried out using crosses between thirteen inbred lines of common wheat (6 lines x 7 testers) and inter-species crosses (T. aestivum L. ? T. spelta L., T. aestivum L. ? T. compactum HOST, T. aestivum L. ? T. sphaerococcum PERCIV., T. aestivum L. ? T. macha DEKAPR. et MENABDE, T. aestivum L. ? T. petropavlovskyi UDACZ. et MIGUSCH, T. aestivum L. ? T. vavilovii (THUM.) JAKUBZ.). The 42 common wheat F1 hybrids were tested during two seasons (2010/11 and 2011/12) on the Selection center Ptuj. The experiment was carried out in a randomized block design with four replications. The 43 interspecies F1 hybrids were tested on the same location in the season 2011/12 and the experiment was designed as an randomized block with three replications. The results were analyzed using statistical package AGROBASE generation II and STATGRAPHICS Centurion XVI. The analysis of variance was significant for both, GCA and SCA variances (P < 0,01). Generally, SCA variances were lower than GCA variances. We could state, that the improvement of heterosis level in the common wheat germplasm through the use of relatives with the same genome (genome BAD) is possible. As an example we can point out the interspecies F1 hybrid between common wheat variety Garcia and an accession of the Triticum sphaerococcum PERCIV. species (accession number 01C0201227).

Inter- and intra-species differences in nitrate uptake and N allocation were studied in wheat seedlings. Two collections of wheat cultivars Triticum aestivum and Triticum durum were grown at controlled conditions in hydroponics (773µM NO<sub>3</sub><sup>–</sup>, i.e. 10.8 ppm N-NO<sub>3</sub><sup>–</sup>). At the age of 3 weeks the net rate of nitrate uptake was measured in depletion experiments and it was expressed as µmol NO<sub>3</sub><sup>– </sup>per g of root fresh weight per hour (µmol/g FW/h). Nitrate uptake capacity of the whole root system was expressed as µmol NO<sub>3</sub><sup>– </sup>per plantper hour (µmol/plant/h). At the same time wheat plants were harvested and analyzed for nitrogen content. In contrast to the net rate of NO<sub>3</sub><sup>– </sup>uptake (3.98–8.57 µmol/g FW/h) the net NO<sub>3</sub><sup>– </sup>uptake capacity of T. aestivum roots (6.37–11.66 µmol/plant/h) significantly differed from T. durum roots (15.26–22.69 µmol/plant/h). Within T. aestivum collection cultivar Roxo exhibits the lowest value in both traits (3.98 µmol NO<sub>3</sub><sup>–</sup>/g FW/h and 6.67 µmol NO<sub>3</sub><sup>–</sup>/plant/h). By contrast Strela was characterized by relatively low NO<sub>3</sub><sup>– </sup>uptake rate (5.47 µmol/g FW/h) and the highest NO<sub>3</sub><sup>– </sup>uptake capacity (11.66 µmol/plant/h). Intra-species differences in T. durum group were not significant. In both species about 70% total nitrogen was found in shoot. Statistically significant differences in nitrogen content and its allocation were affected by growth rate in early stages of development.

The main goal of this work was to identify genotypes of three wheat species Triticum aestivum</i> L., <i>Triticum spelta</i> L., <i>Triticum durum</i> DESF.) on the basis of individual high-molecular-weight glutenin subunits (HMW-GS) and to predict their technological quality. Detection of HMW-GS was carried out by the standard reference method ISTA SDS-PAGE and the Glu-score was calculated according to the catalogue of alleles for HMW-GS. Among the common wheat varieties the highest Glu-score (10) was determined for the cultivars Axis, Istra and Solara. The most frequently occurring HMW-GS in genotypes of <i>Triticum aestivum</i> L. were 0; 7 + 9; 5 + 10. On the other hand, in the spelt wheat the highest frequency of HMW-GS was detected for 2*; 6 + 8; 2 + 12. The Glu-score for <i>Triticum spelta</i> L. genotypes ranged from 6 to 8. Among the <i>Triticum durum</i> DESF. cultivars, up to 71% were characterized by Glu-score 4, which predetermines them for special baking purposes. The most frequent combination of HMW-GS in durum wheat was 0 and 7 + 8. Thus, SDS PAGE of HMW-GS can be used for identification, differentiation and characterization of different species of wheat and for prediction of bread-making quality of wheat.

Abstract The fern Nephrolepis exaltata (L.) Schott, fam. Nephrolepidaceae, has little traditional medicinal use. In order to estimate its potential safety, in the present study we have investigated the phytotoxicity (on Triticum aestivum L.) and toxicity on brine shrimp of extracts from plants grown hydroponically. The species identity was confirmed by macroscopic and microscopic examinations on rhizomes, rachises, pinnae and runners, using bright field and fluorescent microscopy. Biological assays were performed on aqueous and ethanol solutions of the fronds. The brine shrimp lethality assay was performed on Artemia franciscana Kellog and a phytobiological bioassay on Triticum aestivum L. Lethality, root elongation and karyokinetic film modifications were evaluated, and LC50 and IC50 values were calculated. The microscopic analysis revealed the main histo-anatomic elements: polystelic structure and hypodermis (rhizome, rachis, runners), trichomes (rachis), homogenous structure, trichomes and diacytic/anisocytic stomata (leaves). The ethanol and aqueous extracts showed low cytotoxic effects on both Triticum aestivum roots and Artemia franciscana nauplii.

For 17 cultivars of winter wheat (Triticum aestivum L.) different vernalization and photoperiod responses were detected. The effect of photoperiod sensitivity was not significantly changed by vernalization; different vernalization responses were probably due to the presence of multiple alleles at Vrn loci. The delay in heading depended on the vernalization deficit exponentially: y = Parameter (1) + (y0 – Parameter (1)) × EXP (Parameter (2) × (x – x0)). The dependence was shown to be general and significant for the given model in all the studied cultivars. Individual regressions characterised responses of cultivars to a deficit of vernalization treatment. Cluster analysis according to the characterisation obtained (full vernalization requirement, minimum vernalization requirement, insufficient vernalization and parameters of the dependence) showed the relationships between cultivars and enabled their grouping by similar profiles of vernalization, and, possibly, of photoperiod response. In individual cultivars, an attempt was made to use the model to predict performance for some agronomic traits.

This paper deals with the influence of Mg, N and the content of chlorophylls and carotenoids on photosynthetic productivity of two new genotypes of winter wheat, Lara and Perla, at two localities, Donji Miholjac and Kutjevo, during the vegetation periods 1997/1998 and 1998/1999. The applied parameters were determined by standard methods. The results showed effects of Mg concentration on all examined parameters with the exception of chlorophyll b content. The highest correlation coefficient was with the N concentration, significant correlation between the leaf area and N concentrations and between the leaf area and chlorophyll a. Statistical analysis showed very significant relationship between the content of organic matter and examined parameters with a large number of significant correlations. The most important correlation was found between the content of organic matter and N concentration, and between chlorophyll a, chlorophyll b, carotenoids and the content of organic matter. The link between N, Mg and other examined parameters was firm and significant as well as under strong influence of external factors.

A biological phenomenon by which one plant releases some chemicals in the environment that affect the rate of germination, its seedling emergence and physiology and overall growth of neighboring plants is called allelopathy. The significance of study was checked allelopathic phytochemical potential of Daraikh (Melia Azedarach L.) leaves on Wheat. Leaves litter were used to examine the allelopathic effects of Daraikh (Melia Azedarach) at five concentrations (100, 200, 300, 400 g, control) parameters studied germination percentage (%), Speed of germination, plant height (cm), root length (cm), Shoot length (cm), coleoptile length (cm), Fresh weight (g) and dry weight (g), Tiller (plant-1) and chlorophyll content (µ cm-2) of Triticum aestivum. All concentration of Leaves litter of Melia Azedarach showed pronounced inhibitory effect on all parameters of Triticum aestivum. Melia Azedarach exerted phytotoxic influence on Triticum aestivum at initial growth stages. Melia Azedarach exhibited a significant negative impact on germination of Triticum aestivum at 100, 200, 300, 400 g litter of leaves than control (Sterilized soil) repectively. Melia Azedarach halted the coleoptile length of Triticum aestivum @ 400 g leaves litter. Powdered leaves of Melia Azedarach in clay loam soil appeared to have strong allelopathic inhibition under maximum concentrations on growth and germination of Triticum aestivum. Hence, Melia Azedarach proved a strong allelopathic plant that should be planted aside from field to avoid harmful impacts during early growth stages of Triticum aestivum.

Aim. Cytological analysis of the stability of interspecific hybrids of wheat Triticum spelta L. x Triticum aestivum L. Methods. By the method of temporal squashed preparations has been analyzed ploidy level, the frequency of structural chromosome aberrations and abnormalities mitosis in root meristem cells of seedlings. Results. It was revealed that the F1 hybrids have significantly greater number of cells with impaired mitosis compared to the initial parental components. The vast majority of violations of the hybrids was represented by chromosomal aberrations. It is shown that the second-generation simple and bekrossing hybrids are characterized by a certain stabilization of hybrid genomes, which manifests significant reduction in the number of abnormal mitosis. Conclusions. In interspecific hybridization spelled and soft wheat were found that when the maternal component served as spelled and his father - soft wheat total the overall frequency of mitotic abnormalities was less than in the reciprocal crosses, which may be indicative of maternal cytoplasm effect.

This study measured the heritability of in vitro regeneration in wheat (Triticum aestivum L.). Immature embryos of 28 F2-derived families of the spring wheat cross HY912 × HY320 were cultured in the F3, F4, and F5 generations. Highly significant (P < 0.01) genotypic differences were observed for embryo germination, callus induction, embryogenic callus formation, and plantlet regeneration. Comparisons of generation means and mid-parent values suggest that additive variance is an important factor in the inheritance of in vitro regeneration.Key words: Regeneration, in vitro, heritability, Triticum aestivum, wheat
