MdSPL1-MdNF-YB4-MdCKX7 Module Positively Regulates Saline-Alkali Tolerance by Mediating Cytokinin Levels in Apple.
Saline-alkali stress is a major abiotic factor that compromises plant growth, crop yield, and quality. Cytokinin plays an essential role in plant responses to saline-alkali stress; however, the underlying molecular mechanisms remain unclear in apple (Malus domestica). In this study, CYTOKININ OXIDASE/DEHYDROGENASE7 (Md...
