Isolation of a gibberellin-insensitive dwarfing gene, Rht-B1e, and development of an allele-specific PCR marker

Abstract

Gibberellins (GAs) are important phytohormones in plants. GAs promote plant growth by inducing the degradation of DELLA proteins, which serve as GA signal repressors. The semi-dwarfing genes Rht-B1b and Rht-D1b, derived from the Japanese variety Norin 10, are gain-of-function mutant alleles of the reduced height-1 genes (Rht-B1 and Rht-D1) encoding wheat… (More)
