Alien chromosome addition lines are useful genetic material for studying the effect of an individual chromosome in the same genetic background. However, addition lines are sometimes unstable and tend to lose the alien chromosome in subsequent generations. In this study, we report preferential removal of chromosome 1D rather than the alien chromosome from(More)
Psathyrostachys huashanica Keng (2n = 14; N(h)N(h)) is an endangered wheat-related species, with a distribution in the Huashan region of central China. It has many agronomically promising characters including resistance to disease and drought and winter hardiness. We produced hybrids between common wheat as the female parent and P. huashanica as the male(More)
A monosomic addition line of Aegilops tauschii chromosome 1D in Triticum durum cv. PBW114 was produced in 1990. This line was self-pollinated and maintained for several generations while following the presence of chromosome 1D carrying the gene for red glume color. Cytological analysis indicated that two of the three derivative lines had substitution of(More)
Grain hardness is an important quality trait that influences product development in wheat. This trait is governed by variation in puroindoline proteins (PINA and PINB). Our study evaluated 551 Indian wheat germplasm lines for diversity in Pina and Pinb genes. Eighty-two lines were shortlisted for full length sequencing and grain hardness studies. Sequencing(More)
α-Gliadin proteins of the wheat gluten form a multigene family encoded by genomic loci Gli-A2, Gli-B2 and Gli-D2 located on the homoeologous wheat chromosomes 6AS, 6BS, and 6DS, respectively which upon partial digestion elicits celiac disease (CD) in the genetically susceptible individuals. The present investigation was planned to study the variations in(More)
In this paper, we describe a temperature-sensitive mutant of the yeast Saccharomyces cerevisiae (P5-9) which at a restrictive temperature (36 degrees C) shows a pleiotropic defect for transport of many different metabolites. The temperature sensitivity of the mutant is closely related to a reduction in phosphofructokinase activity. This conclusion is based(More)
Wheat cultivars with wide introgression have strongly impacted global wheat production. Aegilops geniculata (MgUg) is an important wild relative with several useful traits that can be exploited for wheat improvement. Screening of Ae. geniculata addition lines indicated a negative effect of 1Ug and the positive effect of 1Mg chromosome on wheat dough(More)
Starch and proteins are major components in the wheat endosperm that affect its end product quality. Between the two textural classes of wheat i.e. hard and soft, starch granules are loosely bound with the lipids and proteins in soft wheat due to higher expression of interfering grain softness proteins. It might have impact on starch granules properties. In(More)
