番茄CBF基因家族全基因组分析
Whole genome analysis of CBF gene family in tomato(Solanum lycopersicum L.)
摘要
Abstract
To identify tomato CBF gene family and the preliminary exploration of the biological function of the SICBFs gene,therefore,in this research,six CBF genes in tomato(Solanum lycopersicum L.)were identified based on the CBF genes of Arabidopsis,rice,and potato.The physicochemical characteristics and tissue expression patterns were systematically compared and analyzed to clarify the function of the CBF gene family in tomato.The results are as follows:1)The phylogenetic tree analysis indicated that all CBF genes were divided into four subgroups.The SICBFs gene family members of tomato were distributed in two subgroups,Group Ⅰ and Group Ⅱ,which were significantly different from the CBFgene of rice(Group Ⅳ).2)The analysis of cis-acting elements revealed a total of 1 072 cis-acting elements could regulate the expression of the CBFgene,among which the growth and development elements were the most,accounting for 72％.3)Tissue transcription analysis demonstrated that SICBF1～SICBF4 were expressed at relatively high levels during the color breaking stage,suggesting that the SICBFs gene might play a significant role in plant growth and development.4)The expression levels of SICBF1～SICBF5 were significantly up-regulated under low-temperature stress.To conclude,the biological function of the tomato CBF gene family and the mechanism of tomato cold tolerance can provide a theoretical basis for new tomato variety creation.关键词
