Genetic Diversity and Population Structure Analysis of European Hexaploid Bread Wheat (Triticum aestivum L.) Varieties
Progress in plant breeding is facilitated by accurate information about genetic structure and diversity. Here, Diversity Array Technology (DArT) was used to characterize a population of 94 bread wheat (Triticum aestivum L.) varieties of mainly European origin. In total, 1,849 of 7,000 tested markers were polymorphic and could be used for population structure analysis. Two major subgroups of whe...
متن کاملThe wheat (Triticum aestivum L.) leaf proteome.
The wheat leaf proteome was mapped and partially characterized to function as a comparative template for future wheat research. In total, 404 proteins were visualized, and 277 of these were selected for analysis based on reproducibility and relative quantity. Using a combination of protein and expressed sequence tag database searching, 142 proteins were putatively identified with an identificat...
متن کاملOptimization of Transient Expression of uidA Gene in Androgenic Embryos of Wheat (Triticum aestivum L. cv. Falat) via Particle Pombardment
Haploid microspore-derived embryos (MDEs) of wheat were obtained by in vitro androgenesis. These embryos were employed to evaluate the transient expression of GUS gene (uidA) following particle bombardment. Using the Bio-Rad PDS-1000/He system, the physical parameters including rupture disk pressure (900, 1100 and 1350 psi); microprojectile travel distance (6 and 9 cm); gold particles size (0....
متن کاملPhysiological assessment of drought tolerance in wheat (Triticum aestivum L.) varieties under moisture stress conditions
Drought is one of the major limiting factors in wheat production in Pakistan. Five commercial wheat varieties; Chakwal-97, Inqilab-91, Margalla-99, NR-234 and Wafaq2001 were grown in pots in glasshouse. Plants were subjected to three consecutive drought cycles at tillering, pre-anthesis and milky growth stages by withholding water till leaf rolling started. Measurements of physiological respons...
متن کاملVernalisation Response of Some Winter Wheat Cultivars (Triticum aestivum L.)
For 17 cultivars of winter wheat (Triticum aestivum L.) different vernalisation and photoperiod responses were detected. The effect of photoperiod sensitivity was not significantly changed by vernalisation; different vernalisation responses were probably due to the presence of multiple alleles at Vrn loci. The delay in heading depended on the vernalisation deficit exponentially: y = parameter (...
