Cotton is the most important commercial crop of India and heterosis in cotton is well documented with 7 to 50 per cent heterosis in interspecific (G. hirsutum x G. barbadense) hybrids, 10 to 138 per cent in intra-hirsutum hybrids and upto 220 per cent in desi (G. herbaceum x G. arboreum) hybrids. Currently hybrid cotton, especially Bt cotton hybrids, occupies more than 80 per cent of cultivated...

A spontaneously reverted iPSC line was identified from an A-T subject with heterozygous ATM truncation mutations. The reverted iPSC line expressed ATM protein and was capable of radiation-induced phosphorylation of CHK2 and H2A.X. Genome-wide SNP analysis confirmed a match to source T cells and also to a distinct, non-reverted iPSC line from the same subject. Rearranged T cell receptor sequence...

Leaf rust caused by Puccinia triticina (Pt) is one of the most important diseases of bread wheat globally. Recent advances in sequencing technologies have provided opportunities to analyse the complete transcriptomes of the host as well as pathogen for studying differential gene expression during infection. Pathogen induced differential gene expression was characterized in a near isogenic line ...

Accurate estimation of sink capacity in rice (grain number × potential grain size), independent filling, is necessary for considering source – interactions. However, how to measure size still a matter debate. Here, we investigated the effect modifying grain-filling environment on 1000-grain weight grains screened by specific gravity or brown thickness, projected area (‘grain area’), husk as can...

Durum wheat (Triticum turgidum L. subsp. durum Desf.) Line 149 contains two novel major genes for excluding Na(+) from leaf blades, named Nax1 and Nax2. The genes were separated into families containing a single gene and near-isogenic homozygous lines were selected. Lines containing either Nax1 or Nax2 had lower rates of Na(+) transport from roots to shoots than their near-isogenic pairs due to...

A long-standing and fundamental question in biology is how genes influence complex phenotypes. Combining near-isogenic line mapping with genome expression profiling offers a unique opportunity for exploring the functional relationship between genotype and phenotype and for generating candidate genes for future study. We used a whole-genome microarray produced with ink-jet technology to measure ...

The sensory value of dry beans (Phaseolus vulgaris L.) is one of the traits that most influence consumer’s choices. It is often argued that the process of genetic improvement might reduce the sensory value of dry beans through negative genetic correlations among traits or through the remnants of the donor genome that are interspersed with the recipient genome through backcrossing. However, ther...
