This study has found numerous novel genetic variants of GA-insensitive dwarfing genes with potential agricultural value for crop improvement. The cultivar, Spica is a tall genotype and possesses the wild-type genes of Rht-A1a, Rht-B1a and Rht-D1a. The cultivar Quarrion possesses a null mutant in the DELLA motif in each of the 3 genomes. This is a first(More)
Using de novo assembly of 46 million paired end sequence reads of length 250 bp for a myrtle rust isolate, we have estimated its genome size to be between 103 and 145 Mb and the number of proteins as >19,000. Annotation of the contigs found a very large percentage of proteins are associated with molecular functions of DNA binding or binding in biological(More)
The HfrDrd gene has been reported to be induced specifically in the wheat’s defence response to Hessian fly larvae and is not a general stress-responsive gene. The gene is located on chromosome 7DS with a homeologue on 7AS. In this study, two SNPs in the gene that result in amino acid substitutions in the dirigent-like protein have been identified. Both are(More)
Tilletia indica, the cause of Karnal bunt of wheat, replaces part of the seed with a black powdery mass containing millions of spores and produces a strong unpleasant odour like rotten fish. The fishy smell has serious consequences for the marketability of wheat. The fungus is thus subjected to very strict quarantine regulations in countries not known to(More)
Tilletia indica causes the disease Karnal bunt in wheat. The disease is under international quarantine regulations. Comparative mitochondrial (mt) genome analysis of T. indica (KX394364 and DQ993184) and T. walkeri (EF536375) has found 325 to 328 SNPs, 57 to 60 short InDels (from 1 to 13 nt), two InDels (30 and 61 nt) and five (>200 nt) presence/absence(More)
