Gene Details:

• Gene ID: Zm00001eb047750
• Gene Symbol: ID1 ZmIDD5
• Gene Name: indeterminate growth1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• INDETERMINATE1 (ID1), a floral transition regulator, inhibits the transcription of ZmMIR399 genes by directly binding to their promoters, alleviating the repression of ZmPHO2 by miR399 and ultimately contributing to the maintenance of Pi homeostasis in maize.
• ID1 expression was independent of the external inorganic orthophosphate status, indicating that ID1 is an autonomous regulator of Pi homeostasis.
• The transcription factor INDETERMINATE1 (ID1) functions as an autonomous upstream regulator of phosphorus homeostasis by suppressing the transcription of ZmMIR399 genes.
• This study provides genetic resources for improving maize phosphorus use efficiency and breeding low phosphorus-tolerant maize varieties by editing the ID1-miR399-ZmPHO2 module.
• ID1-modified plants to fine-tune flowering time and phosphorus uptake in maize.
• ID1 requires extended growth for flowering; vegetatively totipotent with gt1 and factors for perennialism.
