主 题：Rice Tillering Map-based cloning OsCCD8 Feedback regulation
摘 要：Rice tillering is an important determinant for grain *** investigate the mechanism of tillering,we characterized a multiple tillering mutant(mt1) identified from the japonica variety,Zhonghua 11,treated with *** mutant exhibits advanced tillering development and dwarfed compared with wild-type *** analysis and fine gene mapping indicated that the mt1 mutant was controlled by a recessive gene,residing on a 29-kb window on AP003376 of chromosome *** putative gene in this region,encoding a carotenoid cleavage dioxygenase 8(CCD8),was allelic to *** mt1 mutant phenotype was complemented by introduction of wild-type MT1,and knockdown of MT1 in wild-type rice mimicked the mutant ***-time PCR analysis indicated that the MT1 gene is expressed highly in stems and at a low level in axillary buds,panicles,leaves,and *** addition,MT1 expression is clearly under feedback regulation.
