Gene Details:

• Gene ID: MDP0000757701
• Gene Symbol: MdJAZ18MdJAZ2
• Gene Name: jasmonate ZIM-domain protein 18
• Genome: Golden ASM211411v1
• Species: Malus domestica

Functional Descriptions:

• MdSnRK1.1 interacts with MdJAZ18 to regulate sucrose-induced anthocyanin and proanthocyanidin accumulation in apple.
• MdSnRK1.1 then phosphorylated MdJAZ18 to facilitate its 26S proteasome-mediated degradation, which released MdbHLH3 thereby activating the expression of the regulatory and structural genes, thus finally promoting the biosynthesis of anthocyanins and PAs.
• MdJAZ18 is involved in MdSnRK1.1-induced anthocyanin and PA accumulation.
• These findings suggested that MdJAZ18 was involved in MdSnRK1.1-induced anthocyanin and PA accumulation by modulating the expression of the regulatory and structural genes.
• The jasmonate-ZIM domain (JAZ) proteins MdJAZ1 and MdJAZ2 negatively modulate MdABI4-improved cold tolerance in apple by interacting with the MdABI4 protein.
• MdJAZ1 and MdJAZ2 negatively regulated cold tolerance by attenuating the interaction between the MdABI4 and MdICE1 proteins.
• The results showed that compared with MdABI4-overexpressing transgenic apple leaves (MdABI4-OX), MdJAZ1-OX/MdABI4-OX and MdJAZ2-OX/MdABI4-OX transgenic apple leaves accumulated more ROS after cold stress treatment, suggesting that the overexpression of MdJAZ1 or MdJAZ2 decreased MdABI4-improved cold tolerance in apple leaves.
• MdJAZ1 and MdJAZ2 negatively regulate MdABI4-improved cold tolerance.
