查询词典 mutant

Results showed 172 DH plants in 2006, 230 DH plants in 2007 were obtained, 275 plants had been domesticated in 2008.Some DH regeneration plants could transform into leaf mutants. From 2006 to 2007, 8 wrinkledness leaf mutants were gotten. The highest rate of getting mutants was 2.29 %. 2 mutant plants had gotten seeds. The leaf mutants mainly showed wrinkledness in the surface of preceding leaves at early stage. Then the wrinkle leaves could transfer to normal ones and some also keep the wrinkledness later with their growth.

结果表明，CGMCC№2553具有胚胎发生能力，2006年获得172株DH再生植株，2007年获得230株，2008年驯化275株；定植到日光温室中的DH再生植株有些会转变为叶片突变体，2006~2007年共获得8株叶片皱缩突变体，最高获得率为2.29%；目前已获得2份突变体的自交种子；叶片突变体主要表现：生长初期叶片表面皱缩呈瘤状，随着生长的进行，一些皱缩的叶片转变为正常，有的则依然皱缩。

Further studies showed some DH plants could generate two or more than two stems in which wrinkledness mutant and wild types except for the leaf wrinkledness, therefore they were the better materials for studying the wrinkledness characteristic. The finding is useful in studying, locating and cloning the wrinkledness gene linked to leaf mutants of Brassica allosextuple CGMCC № 2553 DH lines in the future.

进一步研究发现，在同一DH再生植株上常常会萌发出皱缩和野生型的2个或多个分枝，由于皱缩和野生型除了叶片皱缩性状不同外，其他性状完全相同，因此叶片突变体和野生型是研究叶片皱缩性状的理想材料，有利于进一步研究皱缩基因的遗传，定位、克隆叶片皱缩相关基因。
