摘要/Abstract

摘要： 旨为获取机械损伤引起的AP2/EREBP、NAC以及WRKY转录因子相关的差异基因。通过将转录组测序后组装的序列转化为Mapman可识别的探针ID,对这三类转录因子进行筛选分析,加上转录组中Swiss-Prot和Nr数据库的注释。获得AP2/EREBP类转录因子差异基因13个,NAC类差异基因8个,WRKY类差异基因11个,在T8和T9时刻时,AP2/EREBP类、NAC类和WRKY类分别出现一个与对照（T7）相比明显下调的差异基因,而在NAC这一类转录因子中,与对照相比,有2个差异基因先下调,再上调,其余三类转录因子的差异基因均处于上调状态。通过数据库注释表明日本结缕草在遭受机械损伤时AP2/EREBP和WRKY类转录因子能够增强对非生物胁迫和生物胁迫的应答能力,增强抗逆性,并且NAC类转录因子传递信号至茎端分生组织并调控其生长。

Abstract: This work aims to obtain differential genes（DEGs）related to AP2/EREBP,NAC,and WRKY transcription factors caused by mechanical damage. These three transcription factors were screened by converting the assembled sequences after transcriptome sequencing into Mapman-recognizable probe IDs,and were annotated from the Swiss-Prot and Nr databases in the transcriptome. Total 13 DEGs of AP2/EREBPs,8 DEGs of NACs and 11 DEGs of WRKYs were obtained. In contrast to control T7（Mechanically damaged 0 h）,one DEG was down-regulated in AP2/EREBPs,NACs,and WRKYs at T8（Mechanically damaged 2 h）and T9（Mechanically damaged 6 h）,respectively;whereas two DEGs of NAC showed up-regulated trend at T8 and down-regulated trend at T9,and the DEGs of other transcriptional factors were all up-regulated at T8 and T9. The database annotation indicated that AP2/EREBP and WRKY transcription factors enhanced the response to abiotic stress and biotic stress,i.e.,enhanced its stress resistance,when Zoysia japonica was damaged mechanically. Moreover,the NAC transcription factor transmitted signals to shoot apical meristem and regulated its growth.
