bif2 barren inflorescence2 gene in Maize
(maize gene reviews submitted to the Maize Genetics Cooperation Newsletter as a way to enable community curation of MaizeGDB are being moved, 2013-14, with author permissions to the wikipedia, and will be grouped to the wiki page maize genes. The initial summary statements for each gene have been previously included in MaizeGDB)
Function. Regulation of auxin transport during axillary Meristem and lateral organ initiation.
Summary[1] The bif2 mutation affects all axillary meristems in the plant. The tassel has fewer branches, spikelets, florets and floral organs (McSteen and Hake 2001).[2] The ear shoot, if it forms, has very few kernels. The mutant plants also have defects in vegetative development as they make fewer tillers (in a tb1 mutant background) and make one or two fewer leaves than normal. The bif2 gene encodes a serine threonine protein kinase (McSteen et al 2007)[3] that phosphorylates auxin efflux carrier ZmPIN1a (Skirpan et al 2008)[4] and BHLH transcription factor BARREN STALK1 (Skirpan et al 2008).[4] Natural variation in bif2 alleles are associated with tassel branch number and plant height (Pressoir et al 2009).[5]
