Novel genetic variants of GA-insensitive Rht-1 genes in hexaploid wheat and their potential agronomic value.

PloS one - 1 Jan 2013

Tan Mui-Keng, Koval Jason, Ghalayini Aida

Abstract excerpt

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 report of a null mutant of Rht-A1. In addition, novel null...
