Ubiquitous miR159 repression of MYB33/65 in Arabidopsis rosettes is robust and is not perturbed by a wide range of stresses

Li, Yanjiao; Alonso-Peral, Maria; Wong, Gigi; Wang, Ming-Bo; Millar, Anthony A


BACKGROUND: The microR159 (miR159) – GAMYB pathway is conserved in higher plants, where GAMYB, expression promotes programmed cell death in seeds (aleurone) and anthers (tapetum). In cereals, restriction of GAMYB expression to seeds and anthers is mainly achieved transcriptionally, whereas in Arabidopsis this is achieved post-transcriptionally, as miR159 silences GAMYB (MYB33 and MYB65) in vegetative tissues, but not in seeds and anthers. However, we cannot rule out a role for...[Show more]
