Dominant and pleiotropic effects of a GAI gene in wheat results from a lack of interaction between DELLA and GID1.

Dominance, semidominance, and recessiveness are important modes of Mendelian inheritance. The phytohormone gibberellin (GA) regulates many plant growth and developmental processes. The previously cloned semidominant GA-insensitive (GAI) genes Reduced height1 (Rht1) and Rht2 in wheat (Triticum aestiv... View More
