| 摘 要： | 对云南元江普通野生稻90个个体Wx基因区段内的重复序列(CT)n和第1内含子供体+1位碱基G/T分别进行了比较分析。结果表明云南元江普通野生稻3个居群中的90个单株在重复序列(CT)n和G/T位点纯合一致,没有多态性;其G/T位点碱基均为G;其重复序列(CT)n基因型与云南地方籼稻品种优势基因型相似但又有所区别。本研究结果为云南元江普通野生稻Wx基因利用和在稻种进化上的地位提供了信息。

| Abstract: | In the present study,the genetic diversity of microsatellite sequence(CT)n and intron 1 G/T in Wx gene were determined for 90 individuals in the natural population of O.rufipogon from Yuanjiang of Yunnan Province.In the loci of the microsatellite sequence(CT)n and intron 1st G/T in Wx gene,all of individuals from the natural population of wild rice in Yuanjiang were homogenetic,whose intron 1 G/T were base G,the band type of microsatellite sequence(CT)n wassimilar to one of the local indica cultivars from Yunnan. |
