Gene Details:

• Gene ID: Zm00001eb086630
• Gene Symbol: si3
• Gene Name: Silky3
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• A maize semi-dominant mutant Silky3 (si3), which displays pleiotropic defects during inflorescence development, including loss of determinacy and identity in meristems and floral organs, as well as the sexual transformation of tassel florets.
• Silky3 mutants have silky ears and tassels and up regulated in mutant plants
• Functional analysis reveals that si3 is a nuclear protein and may act as a transcriptional regulator.
• Transcriptome analysis reveals that the ectopic expression of si3 strongly represses multiple biological processes, especially the flower development pathways.
• pleiotropic inflorescence phenotypes in si3 mutants are attributable to defects in multiple flower-related pathways.
• These results indicated that the complicated mutant phenotypes might be caused by multiple pathway defects in si3 inflorescences.
