【摘要】[目的]检测所筛选的转录因子GhNAC 1-6、GhMYB、GhDREB、GhWRKY在新疆主栽品种新陆早17号中是否响应干旱胁迫.[方法]通过实时荧光定量PCR检测萌发不同时期,在子叶和胚根中转录因子的表达变化.[结果]所有筛选的转录因子都响应PEG模拟干旱胁迫,在胚根中,转录因子集中在4 d响应PEG胁迫.[结论]在棉花种子萌发期干旱胁迫下,所筛选的转录因子都响应干旱胁迫,且在胚根中NAC 1、MYB、WRKY倍数较大.%[Objective]In order to determine whether the selected transcription factor such as GhNAC 1-6、GhMYB、GhDREB、GhWRKY were responding to drought stress in xinjiang's main plant "xinlu morning 17".[Method]The expression changes of transcription factors in cotyledon and radicle were detected by real-time fluorescence quantitative PCR.[Result]All the screened transcription factors were responsive to PEG simulated drought stress,and in the radicle,transcription factors were concen-trated in response to PEG stress in 4
days.[Conclusion]Under the drought stress of cotton seed germi-nation period,the screened transcription factors were all responding to drought stress,and the NAC 1, MYB and WRKY multiples in the radicle were larger.【总页数】6页(P13-18)
