“…the a-amylase promoters of barley, wheat, and rice (Huang et al, 1990a(Huang et al, , 1990bO'Neill et al, 1990;Itoh et al, 1995). Indeed, the wheat protease promoter has been shown to be responsible to GA in barley aleurone cells (Mena et al, 2002;Isabel-LaMoneda et al, 2003), and rice effecter genes are functional in barley aleurone cells (Gubler et al, 1997;Lu et al, 2002).…”
