Protein
Homeobox protein knotted-1-like 6
Organism
Oryza sativa subsp. japonica
Function
Transcription factor that regulates genes involved in development. May be involved in shoot formation during embryogenesis. Overexpression in transgenic plants causes altered leaf morphology (PubMed:10488233, PubMed:8755613, PubMed:9869405). Regulates anther dehiscence via direct repression of the auxin biosynthetic gene YUCCA4 (PubMed:29915329). Binds to the DNA sequence 5'-TGAC-3' in the promoter of the YUCCA4 gene and represses its activity during anther development (PubMed:29915329). Reduction of auxin levels at late stage of anther development, after meiosis of microspore mother cells, is necessary for normal anther dehiscence and seed setting (PubMed:29915329).
Similarity
Belongs to the TALE/KNOX homeobox family.
