WRKY转录因子是植物一类比较大的基因家族,在水稻中已鉴定出102个成员。研究表明WRKY转录因子在植物生长发育、抗病耐逆等方面都具有重要的作用。本研究利用基因芯片数据结合实时定量分析,对水稻OsWRKY转录因子基因在不同的非生物逆境下的表达进行了分析,发现至少有33个OsWRKY基因同时对任何两种非生物胁迫因子做出响应,且所选20个基因中,13个基因可被ABA所诱导。OsWRKY基因这种重叠表达的特性,预示着这些基因在非生物逆境中具有功能多效性,对于培育抗逆境水稻品种具有重要的理论与实践意义。
Comprehensive Expression Analysis Suggests Overlapping of Rice OsWRKY Transcription Factor Genes during Abiotic Stress Responses
WRKY transcription factors as one large and plant-speciifc gene family have been identiifed 102 members in rice. Extensive studies have revealed that WRKY transcription factors not only play important roles in plant growth and development, but also have functions in regulation of responses to biotic and abiotic stress-es. In the present study, microarray data analyses revealed that about 33 OsWRKY genes were overlapping ex-pressed during in various abiotic (salinity, drought, cold, and hot) conditions, 13 among 20 representative Os-WRKY genes were up-regulated in response to ABA. The results of this study provided not only an evidence for the roles of OsWRKY genes associated with crosstalk among abiotic stresses and ABA response pathway, but also a useful reference for the functional analysis of OsWRKY genes in stress tolerance.
