一个水稻金黄色颖壳与节间基因的定位
MOLECULAR MAPPING OF A GOLD HULL AND INTERNODE GENE IN Oryza sativa L.
摘要
Abstract
A gold hull and internode mutant,designated as Zhejing 88GH,was discovered in the progeny of a japonica variety,Zhejing 88,induced by60Co γ-rays irradiation.The hull and internode of this mutant compared with wild-type,shows a more obviously gold color.Genetic analysis revealed that the trait of gold hull and internode was controlled by a single recessive nuclear gene,tentatively designated as gold hull 6(gh6).The F2 population derived from a cross between Zhejing 88GH and Zhenshan 97B,was used as materials,and SSR markers and recessive class analysis method were used,the gh6 gene was roughly mapped at between RM3732 and RM6378 molecular markers on the short arm of chromosome 2 with the genetic distance of 21.2cM and 28cM.Then,with larger F2 mapping population,the gh6 gene was mapped between Indel3 and Indel4 with a physical distance of 90kb.关键词
