Other claims from this paper (9)
- Association MdBES1 positively regulated expression of MdMYB88 under cold stress and pathogen attack.
- Association MdBES1 negatively regulated expression of MdMYB88 under control and drought conditions.
- Association MdBES1 was a positive regulator of cold tolerance and disease resistance in apple.
- Association MdBES1 was a negative regulator of drought tolerance in apple.
- Mechanism MdMYB88 participated in BR biosynthesis by directly regulating the BR biosynthetic genes MdDET2, MdDWF4 and MdBR6OX2.
- Intervention effect Exogenous BR partially rescued the erect leaf and dwarf phenotypes and the defects in stress tolerance in MdMYB88/124 RNAi plants.
- Intervention effect Knockdown of MdMYB88 in MdBES1 overexpression plants decreased resistance to a pathogen and decreased expression of C-REPEAT BINDING FACTOR1.
- Intervention effect Overexpressing MdMYB88 in MdBES1 OE plants increased expression of MdSPL3 and BR biosynthetic genes.
- Mechanism The authors suggest MdMYB88 contributes to MdBES1 function during BR biosynthesis and the stress response.
