Metacaspase orthologs are conserved in fungi, protozoa and plants, however, their roles in plant disease resistance are largely unknown. In this study, we identified a Triticum aestivum metacaspase gene, TaMCA1, with three copies located on chromosomes 1A, 1B and 1D. The TaMCA1 protein contained typical structural features of type I metacaspases domains, including an N-terminal pro-domain. Tran...

Yellow rust (YR) epidemics have affected wheat productivity worldwide. YR resistance (Yr) is eminent in wheat; however, it continuously invaded by evolving pathogen Puccinia striiformis (Pst.). Understanding the Yr genes’ diversity among available germplasm paramount to developing YR-resistant cultivars. In this study, 14 genotypes were screened for their relative index (RRI) and genes/QTL via ...

Stripe rust caused by Puccinia striiformis f. sp. tritici (Pst) is a major constraint in all wheat-growing countries. Surveys conducted during 2015-19 Haryana, maximum stripe severity recorded Yamuna Nagar (28.57%) followed Ambala (23.33%) and least observed Fatehabad (5%).Two commonly prevalent pathotypes 46S119 110S119 were 4 crop seasons 238S119 occurrence two seasons. Infection range was 0-...
