Gene Details:

• Gene ID: Zm00001eb322280
• Gene Symbol: ZmSPL29 ZmSBP18 sbp29
• Gene Name: SBP-transcription factor 29
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• In this study, we combine expressional, genetic, and molecular studies to identify two homologous SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) transcription factors ZmSPL13 and ZmSPL29 as positive regulators of juvenile-to-adult vegetative transition and floral transition in maize.
• We show that both ZmSPL13 and ZmSPL29 are preferentially expressed in leaf phloem, vegetative and reproductive meristem.
• We show that vegetative phase change and flowering time are moderately delayed in the Zmspl13 and ZmSPL29 single knockout mutants and more significantly delayed in the Zmspl13/29 double mutants.
• ZmSPL13 and ZmSPL29 directly upregulate the expression of ZmMIR172C and ZCN8 in the leaf, and of ZMM3 and ZMM4 in the shoot apical meristem, to induce juvenile-to-adult vegetative transition and floral transition.
• ZmSPL29 overexpression plants display precocious vegetative phase transition and floral transition, thus early flowering.
