Abstract:

GlycosyltransferaseⅠ(GT Ⅰ)family is one of the glycosyltransferases,whose main functions involve the glycosyltransferase transfer of flavonoids and the synthesis of starch and sucrose.In order to reveal the role of GTⅠ gene family in the growth and development and high temperature tolerance of japonica rice, and to provide a basis for the functional study of GT Ⅰ gene family members in japonica rice,and provide ideas for rice variety improvement and high temperature tolerance. 30 members of GT Ⅰ gene family were identified by bioinformatics methods.The gene structure,physicochemical properties of proteins,chromosome location,gene evolution,phylogenetic relationship,conserved domain and protein three-dimensional structure modeling of members of GTⅠ genes in japonica rice were analyzed by bioinformatics.The results showed that 30 GT Ⅰ family members of japonica rice were distributed on 12 chromosomes of rice and the promoters of GT Ⅰ family members predicted abscisic acid response.The three-dimensional structure of family proteins was conserved and contained 6 β-folds and 7 α-helix.Transcriptome data and Real-time fluorescence quantitative analysis showed that most members of GT Ⅰ gene family responded to high temperature stress at 6 h after high temperature treatment.The expression level of OS-GT29 was continuously high.GT Ⅰ family was functionally similar in Arabidopsis thaliana and rice.

Key words: Japonica rice, Glycosyltransferase Ⅰ, Gene family, Bioinformatics, High temperature stress response
