Analysis of BES1 and BRI1 gene transcript levels in barley cultivar Akashinriki (Aka) and its uzu derivative (Aka-uzu), as determined by quantitative RT-PCR analysis. Germinating seedlings were transferred to Hoaglands solution and the leaf samples are harvested after 48 and 72 hours for RNA extraction. (A) Brassinazole-resistant-2 (BES1) (Contig7854_at). (B) Brassinosteroid insensitive-1 (BRI1) (Gene id: AB109215.1). Bars indicate SEM (LSD0.05 A = 0.0003, B = 0.0048).
