摘要:

为了研究TIFY基因家族在甜瓜(Cucumis melo L.)低温胁迫响应中的作用,利用生物信息方法对甜瓜中TIFY家族成员进行全基因组鉴定,并结合转录组数据和实时荧光定量PCR技术,分析其在各组织及低温胁迫下的表达模式。结果表明,甜瓜中共鉴定到15个TIFY家族基因,可分为JAZ、TIFY、ZIM和PPD四个亚家族,分布在9条染色体上。组织表达分析显示,CmTIFY在不同组织部位中均有表达,其中CmTIFY5ACmTIFY5BCmTIFY5CCmTIFY5DCmTIFY9B在花器官中的表达量高于其他组织。随着果实成熟,CmTIFY5B基因表达量逐渐上升,而CmTIFY6B逐渐下降,CmTIFY5BCmTIFY6B可能参与甜瓜果实成熟及品质形成的调控。低温胁迫下,多数CmTIFY基因表达量上调,其中CmTIFY5BCmTIFY5C的上调最为显著。

Abstract:

To investigate the role of the TIFY gene family in the low temperature stress response of melon(Cucumis melo L.),genome-wide identification of TIFY family members was performed using bioinformatics approaches. Tissue-specific expression patterns and low temperature stress responsive profiles were further analyzed through transcriptome sequencing and quantitative reverse transcription polymerase chain reaction technology. The results demonstrated that a total of 15 TIFY family genes were identified in melon,classified into four subfamilies:JAZ,TIFY,ZIM,and PPD,and distributed across nine chromosomes. Tissue-specific expression analysis revealed that CmTIFY genes were expressed in various tissues. Among them,CmTIFY5ACmTIFY5BCmTIFY5CCmTIFY5D and CmTIFY9B exhibited higher expression levels in flowers compared to other tissues. With fruit ripening,the gene expression level of CmTIFY5B gradually increased,whereas that of CmTIFY6B gradually decreased. CmTIFY5B and CmTIFY6B may be involved in the regulation of melon fruit ripening and quality formation. The expression levels of most CmTIFY genes were up regulated under low temperature stress,among which CmTIFY5B and CmTIFY5C were most significantly up regulated under low temperature.
