| 摘 要： | 在水稻品种宜香B中发现了一个白化转绿叶突变体，经过多代自交获得了稳定的白化转绿叶色突变体。该突变体在4叶期前叶色为黄绿色，之后逐渐变绿，从苗龄4周到12周，突变体/野生型叶绿素含量比值从34.5%逐渐升高到99.4%。遗传分析表明该突变受1对隐性核基因控制，暂命名为gra。利用微卫星标记将gra初步定位于第10染色体标记RM596和RM5620之间，进一步利用极端个体定位法把gra精细定位于标记RM25522和RM25535之间。gra基因距RM25522和RM25535标记的遗传距离均为0.05 cM， 其物理距离约为136 kb。

| Abstract: | A green-revertible albino leaf mutant was found in an indica rice variety,Yixiang B,in the field.A stably inherited mutant with green-revertible albino leaf was obtained after five successive generations of self-crossing,and temporarily named as gra.The leaf color of gra was albino before 4th leaf stage,and then gradually turned green.As the content of chlorophyll in leaves increased from 4-week-old to 12-week-old seedlings,the ratio of mutant/wild chlorophyll content in rice leaves rose from 34.5% to 99.4%... |
