从八倍体小黑麦的单、双倍体来自同一植株的成对愈伤组织细胞系中，选择了三对在盐分浓度不同的培养基上进行变异体筛选，并测定耐盐变异体的出现频率。

Point mutation and additional sequence insertion in introns might have given rise to new isoforms.

对比usf1和usf2的各个选择性剪接变体发现，二者的剪接模式都很保守，而新的变体是由点突变或内含子中额外序列的插入造成的。

The different which can represent a phoneme in different phonetic environments are called the allophones of that phoneme.

音位变体是一个音位在特定的语音环境力的具体体现，同一音位在不同语音环境里体现为不同的变体，也就是语音。

The latter is called complementary distribution; they are two allophones of the same phoneme. They only occur in different environments.

互补分布是指音位变体之间的关系，同一个音位的不同变体在语音组合中永远不会出现在相同的位置上，它们没有区别意义的作用，如 top 中的送气的和 stop 中不送气的。
