Gene Details:

• Gene ID: GRMZM2G024530
• Gene Symbol: ZmPTF1
• Gene Name: Pi starvation-induced transcription factor1
• Genome: B73_RefGen_v3
• Species: Zea mays

Functional Descriptions:

• ZmPTF1, a phosphate starvation-induced basic helix-loop-helix (bHLH) transcription factor, contributes to root development and low-phosphate tolerance in maize.
• ZmPTF1 expression, drought tolerance, and the underlying mechanisms were studied by using maize ZmPTF1 overexpression lines and mutants.
• ZmPTF1 was found to be a positive regulator of root development, ABA synthesis, signalling pathways, and drought tolerance.
• The bHLH family member ZmPTF1 regulates drought tolerance in maize by promoting root development and abscisic acid synthesis.
• Knockdown of ZmPTF1 slowed root system development by reducing the number and growth of lateral roots.
• Overexpression of transcription factor ZmPTF1 improves low phosphate tolerance of maize by regulating carbon metabolism and root growth
• Overexpression of ZmPTF1 enhanced the expression of fructose-1,6-bisphosphatase and sucrose phosphate synthase1 participated in sucrose synthesis in the leaves but decreased them in the root, and reduced the expression of genes involved in sucrose catabolism in the roots.
