Bioinformatics analysis and expressed level of histone methyltransferase genes in Lonicera japonica / 中国中药杂志

ABSTRACT

Twenty-three histone methyltransferase genes were obtained from transcriptome dataset of Lonicera japonica. The nucleotide and proteins characteristics, subcellular localization, senior structural domains and conservative forecasting were analyzed. The result of phylogenetic tree showed that 23 histone methyltransferases were mainly divided into two groups lysine methyltransferase and arginine methyltransferases. The result of gene expression showed that 23 histone methyltransferases showed preference in terms of interspecies and organs. They were more expressed in buds of L. japonica than in L. japonica var. chinensis and lower in leaves of L. japonica than in L. japonica var. chinensis. Eight genes were specific expressed in flower. These results provided basis for further understanding the function of histone methyltransferase and epigenetic regulation of active ingredients of L. japonica.
