For this purpose, the barley leaves, prior to the pre-harvest period, which were infected with pathogen at the sexual period developmental stage as Cleistothecium were collected in 2007 and stored in the laboratory at room temperature. Pathogenic isolates were obtained in laboratory conditions with the aid of susceptible control variety (Bulbul-89) by stimulating ascospore output from each foliar. Every isolate was further purified through multiplying from a single spore. A total of 138 Blumeria graminis f. sp. hordei single spores were obtained. The differential isogenic lines of 25, each possessing a single resistance genes were inoculated with the single spore isolates obtained from Cleistothecium. The aggressiveness of gene frequencies and virulence gene complexities, and pathotype frequencies of the isolates were determined according to the scale 0-4, developed by Welz. The pathotypes were established through the formula developed by Habgood. Virulence gene frequencies varied from 0 % to 94.33 % in powdery mildew populations. Gene frequencies of Val, (Va7+Vk) were at 0.0 % in both populations. In the populations of Adana and Hatay 47 and 56 pathotypes were obtained, respectively. The isolate with Habgood pathotype index of 04667601 showed 14.8 % gene frequency in Adana population.DOSAP Program of METU; State Planning Organization, DPTTurkiye Cumhuriyeti Kalkinma Bakanligi [DPT2004K120750]We gratefully acknowledge Dr. Mogens S.

Along with the rise in wheat production, improvement of the nutrient value of wheat varieties is another crucial challenge faced by wheat breeders. It is well established that more than 40% people in the world are at a risk of malnutrition caused by the deficiency of Fe, Zn and protein in their food. Numerous strategies are adopted by scientists, breeders and food industries to combat the problem. In this context, biofortificaton has become a successful method for increasing , either genetically or agronomically, the micronutrient content in crop plants. Recently, substantial progress has been made in the use of molecular marker systems and quantitative trait loci (QTL) to augment the wheat iron, zinc and protein content. Determining the role of GPC-B1 gene in controlling the iron, zinc and protein content in wheat genotypes is a promising discoveries. Although the gene is found to be associated with an elevated micronutrient content, it is also responsible for a decrease in yield. In order to simultaneously achieve both high nutrient content and elevated yield, major efforts are required to reveal the genetic control of these traits. Moreover, identifying the wheat genomic resources with an elevated nutrient content can be crucial. Employment of the next generation sequencing methods and use of molecular markers in marker assisted selection appears to be a promising approach to attaining the objective of breeding nutrient rich varieties. Combining advanced molecular biology and plant breeding techniques for wheat development is a potential strategy in achieving a healthy, 'hid-den hunger' free world.

However, its excess in the soil causes severe damage to plant tissues, which affects the final yield. Wheat, one of the main staple crops, has been reported to be largely affected by B toxicity stress in arid and semi-arid regions of the world. The prevalence of B toxicity stress can be addressed by utilizing wild wheat genotypes with a variant level of stress tolerance. Wild wheat relatives have been identified as a prominent source of several abiotic stress-tolerant genes. However, Aegilops species in the tertiary gene pool of wheat have not been well exploited as a source of B toxicity tolerance. This study explores the root and shoot growth, proline induction, and extent of lipid peroxidation in 19 Aegilops accessions comprising 6 different species and the B-tolerant check wheat cultivar Bolal 2973 grown under Control (3.1 μM B), toxic (1 mM B), and highly toxic (10 mM B) B stress t...

The wild relatives of crop plants exhibit enhanced tolerance to environmental stresses due to reduced severity of selection of agriculturally important traits. Wild bananas represent a largely untapped wealth of genetic diversity. Although some wild relatives of the banana crop have been screened for their tolerance to different biotic and abiotic stresses, many remain to be explored. The wild bananas show more hardiness and higher resilience to different stressors in comparison to their cultivated counterparts. They have been harnessed in banana improvement programmes to enhance stress tolerance and productivity. To utilise wild bananas for crop improvement, they need to be readily available to breeders. This warrants devising conservation strategies and the development and maintenance of centres from which different accession...

There has recently been an increase in the prevalence of gluten-related disorders including celiac disease and non-celiac gluten sensitivity. Therefore, this study has been designed for improving bread production for gluten-free bread (sorghum and potato starch) using hydroxypropyl methylcellulose (HPMC) and whey protein concentrate (WPC-70) as technological improver and optimizing it using response surface methodology (RSM). RSM was used to investigate the influence of predictor variables (HPMC and WPC-70) on bread quality in terms of crust and crumb texture and color, flavor, porosity and overall acceptability. The HPMC level varies from 2- 3% and WPC-70 from 12-15%. Quadratic models are developed to fit with experimental data. The predictor variables had desirable effect on all the responses. Finally, 3% HPMC and 15 % WPC-70 were chosen as optimum levels. The obtained gluten-free b...

The production of bananas requires a certain amount of precipitation throughout the year, and its scarcity reduces productivity in rain-fed banana-growing areas due to drought stress. To increase the tolerance of banana crops to drought stress, it is necessary to explore crop wild relatives (CWRs) of banana. Although molecular genetic pathways involved in drought stress tolerance of cultivated banana have been uncovered and understood with the introduction of high-throughput DNA sequencing technology, next-generation sequencing (NGS) techniques, and numerous “omics” tools, unfortunately, such approaches have not been thoroughly implemented to utilize the huge potential of wild genetic resources of banana. In India, the northeastern region has been reported to have the highest ...

B toxicity adversely affects the wheat yield all around the world, particularly in the arid and semiarid regions. Aegilops, the nearest wild wheat relatives, could be an efficient source to develop B toxicity tolerance in modern cultivars. However, to potentially utilize these species, it is necessary to understand the underlying mechanisms that are involved in providing them tolerance. Other than hampering cellular and physiological activities, high B inhibits the uptake of nutrients in wheat plants that lead to nutrients deficiency causing a hindered growth. Thus, it is crucial to determine the effect of B toxicity on nutrient uptake and finally, to understand the role of nutrient homeostasis in developing the adaptive mechanism in tolerant species. Unfortunately, none of the studies to date has explored the effect of high B supply on th...

Several studies have reported large losses in wheat due to high B in arable land. The identification of different B-toxicity-tolerant wheat germplasm and using them in breeding programs to develop tolerant cultivars is a potential solution to B toxicity. However, tolerance to B toxicity in such germplasm largely relies on the molecular changes in plants under B toxicity at the transcriptome level. Thus, the aim of this study is to determine the transcriptomic response of the roots of a B-toxicity-tolerant Triticum zhukovskyi genotype, PI296968, grown in a highly toxic B environment (10 mM B) in comparison with a control (3.1 μM B) treatment. T. zhukovskyi is a hexaploid wheat species forming a separate lineage from the main wheat lineage and can be a good source of genes for various stresses. However, it has been hardly explored for tolerance to any a...
