Abstract

Abstract: Abstract: Trihelix transcription factors play a significant role in the regulation of plant growth and development, as well as in response to environmental stresses, and belong to a small family. In order to provide theoretical basis for further study of biology function of pepper Trihelix transcription factors, this paper systematically elaborates the characteristics and phylogenetic relationships of pepper Trihelix transcription factor family. Based on the pepper genome database, pepper Trihelix gene family were identified using HMMER 3.0 software and the functional domain of the protein was verified by CDD. A phylogenetic tree was created using the MEGA5.2 software. Motif and chromosomes locations of protein sequence were done by MEME and MapInspect tools. Identified systematically 28 Trihelix family genes from pepper, then was classified into GT-1、GT-2、GTγ、SIP1 and SH4 five subfamilies according to the known Arabidopsis thaliana Trihelix protein family as reference sequences. Gene mapping analysis showed that pepper Trihelix genes were distributed unevenly on 12 chromosomes, among which there was no distribution of pepper Trihelix members on chromosomes 7 and 11. Conserved components analysis indicated that the part of pepper Trihelix genes family was highly conserved, and each subfamily has a special domain. These results suggested that the majority of pepper Trihelix genes were highly conserved, conservative motif and the cluster analysis have a consistence?of high degree and might participated in the multiple regulation process of growth, development and environmental stress in pepper.
