Ancestral QTL Alleles from Wild Emmer Wheat Improve Drought Resistance and Productivity in Modern Wheat Cultivars
Wild emmer wheat (Triticum turgidum ssp. dicoccoides) is considered a promising source for improving stress resistances in domesticated wheat. Here we explored the potential of selected quantitative trait loci (QTLs) from wild emmer wheat, introgressed via marker-assisted selection, to enhance drought resistance in elite durum (T. turgidum ssp. durum) and bread (T. aestivum) wheat cultivars. Th...
متن کاملAncestral QTL Alleles from Wild Emmer Wheat Enhance Root Development under Drought in Modern Wheat
A near-isogenic line (NIL-7A-B-2), introgressed with a quantitative trait locus (QTL) on chromosome 7AS from wild emmer wheat (Triticum turgidum ssp. dicoccoides) into the background of bread wheat (T. aestivum L.) cv. BarNir, was recently developed and studied in our lab. NIL-7A-B-2 exhibited better productivity and photosynthetic capacity than its recurrent parent across a range of environmen...
متن کاملLinkage Relationships in Wild Emmer Wheat, TRITICUM DICOCCOIDES.
The linkage relationships in wild emmer wheat, Triticum dicoccoides , between nine enzymatic loci (Mdh-1, Ipo, beta-Glu, Pept-1, Pept-3, Est-5, Est-1, 6Pgdh-2 and Hk) and a coleoptile pigment locus (Rc) were investigated. Chromosome locations of genes were inferred from analysis of ditelocentric lines of Triticum aestivum, cultivar Chinese Spring. The loci Mdh-B1 and Hk are linked (lambda = 0.1...
متن کاملAllelic variation at high-molecular weight and low-molecular weight glutenin subunit genes in Moroccan bread wheat and durum wheat cultivars
Glutenin is a major protein fraction contributing to the functional properties of gluten and dough. The glutenin constitutes 30-40% of the protein in wheat flour and about half of that in gluten. It is essential to identify correct glutenin alleles and to improve wheat quality by selecting alleles that exert favorable effects. Moroccan wheat cultivars are unique in West Asia and North Africa re...
متن کاملGenome-Wide Identification and Characterization of Salinity Stress-Responsive miRNAs in Wild Emmer Wheat (Triticum turgidum ssp. dicoccoides)
MicroRNAs (miRNAs) are a class of endogenous small noncoding RNAs which regulate diverse molecular and biochemical processes at a post-transcriptional level in plants. As the ancestor of domesticated wheat, wild emmer wheat (Triticum turgidum ssp. dicoccoides) has great genetic potential for wheat improvement. However, little is known about miRNAs and their functions on salinity stress in wild ...
