GA2oxA9 expression is increased in Rht18 and Rht14 wheat isolines. GA2oxA9 expression relative to actin in elongating peduncle tissue from tetraploid (A) and hexaploid (B) wheat. Data are mean values of four biological replicates ± se. Different letters indicate significant differences between Anhinga, Icaro (Rht18), and M24, between Langdon, fixed tall, and fixed short segregants from Icaro x Langdon mapping population, and between Halberd-Rht18 isolines (ANOVA, P < 0.05). Significant differences between Castelporziano (Rht14) and Capelli are indicated by asterisks (Student’s t test,***P < 0.001).
