Gene Details:

• Gene ID: MDP0000452772
• Gene Symbol: MdJAZ1
• Gene Name: jasmonate-ZIM domain (JAZ) protein 1
• Genome: Golden ASM211411v1
• Species: Malus domestica

Functional Descriptions:

• 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.
• In addition, we found that the JA signaling repressor MdJAZ1 interacted with MdTRB1 and interfered with the interaction between MdTRB1 and MdMYB9, therefore negatively modulating MdTRB1-promoted biosynthesis of anthocyanin and proanthocyanidin.
