摘要
NAC(NAM/ATAF/CUC)转录因子是植物所特有的基因家族,在调控植物非生物胁迫的反应中具有重要的作用。为此,研究分析了20个与逆境相关的番茄NAC(SSLNACs)基因在不同非生物胁迫下的表达模式。结果表明,相比于对照,13个SSLNACs基因可以被干旱胁迫诱导表达,10个SSLNACs基因可以被高盐诱导表达,17个SSLNACs基因可以被低温诱导表达。在这些基因中,SSLNAC1、SSLNAC6、SSLNAC7、SSLNAC9、SSLNAC14、SSLNAC15、SSLNAC17和SSLNAC20基因的表达可以被干旱、高盐和低温胁迫所诱导,表现出重叠的表达特性,这种重叠表达的特性预示其在不同非生物胁迫中的功能多效性。研究结果为番茄NAC转录因子家族抗逆基因的功能分析奠定了基础。
NAC(NAM/ATAF/CUC)transcription factors are plant specific gene families,which play important roles in the response on abiotic stresses.The expression patterns of 20 stress relative tomato NAC(SSLNACs)genes under different abiotic stresses are studied.Compared with the control,13 SSLNACs genes can be induced by drought stress,10 SSLNACs genes can be induced by high salt,and 17 SSLNACs genes can be induced by low temperature.Among these genes,the expression of SSLNAC1,SSLNAC6,SSLNAC7,SSLNAC9,SSLNAC14,SSLNAC15,SSLNAC17,and SSLNAC20 genes can be induced by drought,high salt,and cold,which indicate their functional pleiotropy in different abiotic stresses.This study has laid a foundation for the functional analysis of stress resistance genes of tomato NAC transcription factor family.
