Application

Application Comment Organism
agriculture quantitative trait locus Qsd2-AK at SD2 is the single major determinant explaining the difference in seed dormancy between the dormant cultivar Azumamugi (Az) and the nondormant cultivar Kanto Nakate Gold (KNG). The dormant Az allele of MKK3 is recessive, the N260T substitution in this allele decreases MKK3 kinase activity and appears to be causal for Qsd2-AK. The N260T substitution occurs in the immediate ancestor allele of the dormant allele, and the established dormant allele became prevalent in barley cultivars grown in East Asia, where the rainy season and harvest season often overlap Hordeum vulgare
