摘要
DREB(Dehydration Responsive Element Binding Protein)转录因子是AP2/ERF类转录因子的一个亚家族,在植物抗逆过程中发挥关键作用。为更深入地理解花生Ah DREB转录因子的特点与功能,本研究采用生物信息学的方法对Ah DREB基因家族进行了分析。本研究发现花生中共有22个Ah DREB基因,并进一步分析了Ah DREB基因家族成员基因结构特点、遗传进化关系、组织表达情况以及逆境胁迫响应。研究结果表明,Ah DREB转录因子可以分成6类,每一类基因结构具有明显不同的特点。Ah DREB在22个正常不同组织中表达量均较低,但在逆境胁迫条件下,部分Ah DREB基因表达明显提高。本研究为深入分析Ah DREB基因在逆境胁迫中的作用奠定了理论基础。
Dehydration Responsive Element Binding Protein(DREB)transcription factor is a sub-family of AP2/ERF transcription factors that plays a key role in plant stress tolerance.In this study,a total of 22 Ah DREB genes were found in peanut(Arachis hypogaea L.)by bioinformatics analysis.The structural characteristics,evolutionary relationships,expression patterns of Ah DREB family members were further analyzed.The results showed that Ah DREBs could be divided into six catego-ries,each of which has distinctly different characteristics.The expression levels of most Ah DREBs were low in 22 different tissues.However,some Ah DREB genes expression showed significantly in-creased under abiotic stress.This study laid a theoretical foundation for further analysis of the role of AhDREBs in response to abiotic stress.
