In silico molecular and morphological analysis of rice blast resistant gene Pi-ta in Sri Lankan rice germplasm [PDF]
Journal of Genetic Engineering and Biotechnology, 2021 Background Pi-ta is a major blast resistant gene, introgressed from indica rice varieties. In this study, diversity of the Pi-ta gene of 47 Sri Lankan rice accessions was studied by bioinformatics, and the results were validated with molecular and ...

Fitness benefits play a vital role in the retention of the Pi-ta susceptible alleles. [PDF]
Genetics, 2022 In plants, large numbers of R genes, which segregate as loci with alternative alleles conferring different levels of disease resistance to pathogens, have been maintained over a long period of evolution. The reason why hosts harbor susceptible alleles in

Identifying mutations in sd1, Pi54 and Pi-ta, and positively selected genes of TN1, the first semidwarf rice in Green Revolution. [PDF]
Bot Stud, 2022 Background Taichung Native 1 (TN1) is the first semidwarf rice cultivar that initiated the Green Revolution. As TN1 is a direct descendant of the Dee-geo-woo-gen cultivar, the source of the sd1 semidwarf gene, the sd1 gene can be defined through TN1 ...
