The SPL transcription factor MdSPL2 positively regulates drought tolerance in apple.
SQUAMOSA promoter-binding protein-like (SPL) transcription factors play crucial roles in plant abiotic stresses. In this study, the MdSPL2 gene was isolated from apple. Ectopic expression of MdSPL2 in Arabidopsis conferred enhanced tolerance to drought stress. Under drought stress, reduced malondialdehyde (MDA) content...
