Identification and Expression Analysis of TCP Transcription Factor Family Members in Dontostemon elegans
摘要
Abstract
Dontostemon elegans is an important species in the desert ecosystem of Dabancheng,with excellent characteristics of drought resistance and salt tolerance.TCP(teosinte branched 1/cycloidea/proliferating cell factor)as a unique type of transcription factor in plants,the family is widely involved in the regulation of plant growth,development,and stress response.In this study,bioinformatics methods were used to identify the members of the TCP cell factor and analyzed their expression patterns.Twenty-two DeTCPs were identified from the transcriptome of D.elegans,and the proteins encoded by these members all contained a TCP domain.Phylogenetic analysis showed that DeTCPs could be divided into 2 categories and 3 subfamilies.The members of the same group had similar gene structures,and the distribution of conserved domains of the encoded proteins was similar.The expression pattern analysis showed the expression of the 5 DeTCPs members was tissue-specific in the D.elegans,5 DeTCPs were significantly up-regulated under NaCl stress(P＜0.05).Under PEG stress,3 DeTCPs were significantly up-regulated,and the relative expression of 2 DeTCPs was significantly down-regulated(P＜0.05).In summary,this study showed that the members of the DeTCPs contained the basic characteristics,had tissue expression specificity,and responded to drought and salt stress.The members of the family might be involved in the regulation of drought and salt stress resistance.This study provides a data basis and basis for further mining the function of TCPs.关键词
