文摘
- •
The MdSIZ1 is a SUMO (small ubiquitin-related modifier) E3 ligase in apple and plays an important role in responding to stress conditions.
- •
The SUMOylation of MdCIbHLH1 is dependent on MdSIZ1 in vitro.
- •
MdSIZ1 mediated SUMOylation in response to stress conditions in vivo.
- •
The ectopic expression of MdSIZ1 in Arabidopsis siz1-2 mutant plants partially complemented the morphological mutant phenotypes and enhanced the levels of SUMO conjugation.
