Gene Details:

• Gene ID:
• Gene Symbol: PtomtAPX
• Gene Name: mitochondrial ascorbate peroxidase
• Genome:
• Species: Populus tomentosa

Functional Descriptions:

• PtomtAPX, a mitochondrial ascorbate peroxidase, plays an important role in maintaining the redox balance of Populus tomentosa Carr.
• PtomtAPX is an autonomous lignification peroxidase during the earliest stage of secondary wall formation in Populus tomentosa Carr.
• PtomtAPX was relocated to cell walls undergoing programmed cell death and catalysed lignin polymerization in vitro.
• PtomtAPX is crucial for catalysing lignin polymerization during the early stages of secondary cell wall formation and xylem development, and describe how xylem cells provide autonomous enzymes needed for lignin polymerization during rapid formation of the secondary cell wall by coupling with the programmed cell death process.
