Gene Details:

• Gene ID:
• Gene Symbol: PuMYB54
• Gene Name: R2R3-MYB transcription factor 21
• Genome:
• Species: Pyrus ussuriensis

Functional Descriptions:

• PuMYB21 and PuMYB54, from “Nanguo” pears, which were notably expressed in response to cold stress and during the peel-browning process.
• PuMYB21 and PuMYB54 directly bind to the promoter of PuPLDβ1 (a key enzyme catalyzing the hydrolysis of membrane phospholipids) and activate its expression, which probably enhances the degradation of membrane phospholipids and eventually results in peel browning.
• The overexpression of PuMYB21 and PuMYB54 can greatly activate the transcription of endogenous PuPLDβ1 in both “Nanguo” pear fruits and calli, and their silencing can inhibit its transcription.
• PuMYB21 and PuMYB54 may have roles in membrane lipid metabolism by directly binding to the downstream structural gene PuPLDβ1 during the low temperature-induced peel browning of “Nanguo” pears.
