Whole-genome Analysis of CCT Gene Family and Their Responses to Phytohormones in Aegilops tauschii
摘要
Abstract
The control of flowering time is a crucial environmental adaptation in plants;numerous CCT domain genes control flowering in plants.Bioinformatics was used for a genome-wide research of CCT domain genes in Aegilops tauschfi.In this study,26 CCT domain genes were identified in A.tauschfi,distributed on seven chromosomes of the A.tauschfi genome.The predicted molecular weight of this family was spread over 14.9 to 83.2 kDa,and 25 proteins contain a complete CCT conserved structure domain.Twelve pairs of A.tauschii-Triticum urartu and 9 pairs of A.tauschii-rice CCT proteins were orthologous in the phylogenetic tree.Specific expression and constitutive expression were found in the CCT gene family;nine AetCCT genes were constitutively expressed in all organisms,including AetCCT3,AetCCT4,AetCCT7 and AetCCT9;AetCCT15,AetCCT21 and AetCCT25 were specifically expressed in leaf,seed and roots of A.tauschii,respectively.Moreover,the members responded to phytohormone treatments differently,which suggested a complex function and characteristic in metabolism of this family.Light conditions affect the expression of AetCCT,and this gene family is regulated by photoperiod and vernalization.The results of this paper not only provide useful information for wheat evolution studies,but also provide theory basis for comprehensive understanding of formation and interaction characteristics of important traits.关键词
