低能N^+辐照小麦Wis2-1A对其邻近基因表达的影响

Transcription of Retrotransposon Wis2-1A in Wheat after Low-energy N^+ Implantation and Its Effect on Expression of Flanking Genes

用转座子显示技术研究了小麦反转录转座子Wis2-1A在注量为5×1017N+/cm2的低能离子束处理后的转录及其对邻近基因表达的影响,结果发现:在较高注量下,由于Wis2-1A的高水平转录导致其邻近的某些基因沉默。

The transposon display technique was used to study the effects of transcription of retrotransposon Wis2 - 1A in wheat after being implanted with 5×10^17N^＋/cm^2 low-energy ion beam on the expression of flanking genes. The results showd that the over-expressed is 2 - 1A led to the silence of some adjacent genes in higher dose of low-energy N^＋ implantation.
