【摘要】：CBF(C-repeat binding factor)基因家族是AP2轉(zhuǎn)錄因子家族的一類成員,在植物抵御低溫脅迫與提高抗寒性中發(fā)揮著重要作用。為探究胡楊CBF基因家族的特性,本研究在胡楊基因組水平上共搜索到8個PeuCBFs成員,分布于6條scaffolds上,其中PeuCBF1和PeuCBF5的氨基酸和編碼序列相同。對PeuCBFs在胡楊8個組織和5種非生物脅迫下的表達特性進行分析,發(fā)現(xiàn)PeuCBFs主要在幼葉或雌雄花序中表達;PeuCBFs的表達受低溫脅迫的顯著誘導,同時受鹽、干旱和ABA脅迫誘導,但是受高溫脅迫抑制。研究結(jié)果概括了胡楊CBF基因家族的基本特性,為進一步解析PeuCBFs的功能提供了參考。
[Abstract]:The CBF(C-repeat binding factor gene family is a member of the AP2 transcription factor family, which plays an important role in plant resistance to cold stress and cold resistance. In order to explore the characteristics of CBF gene family of Populus euphratica, In this study, eight PeuCBFs members were found at the genomic level of Populus euphratica and distributed on 6 scaffolds. The amino acids and coding sequences of PeuCBF1 and PeuCBF5 were the same. The expression characteristics of PeuCBFs in 8 tissues and 5 abiotic stresses of Populus euphratica were analyzed. It was found that the expression of PeuCBFs was mainly induced by low temperature stress, salt stress, drought stress and ABA stress, but inhibited by high temperature stress in young leaves or male and female inflorescences. The basic characteristics of CBF gene family of Populus euphratica were summarized. It provides a reference for further parsing the function of PeuCBFs.
