VQ蛋白含有一个保守的短的FxxxVQxLTG氨基酸序列基序。一些VQ蛋白在植物的发育过程和非生物/生物胁迫中发挥重要作用。然而，目前还没有对植物中VQ家族的系统研究。结果表明，第Ⅰ类基因在被子植物发育过程中具有保守性，第Ⅳ类和第X类基因在真双子叶植物中与干旱响应有关，第Ⅰ类和第Ⅳ类基因在真双子叶植物中与盐胁迫响应有关，而在单子叶植物中与盐胁迫响应有关，第Ⅱ类和第Ⅳ类基因在被子植物中与冷胁迫响应有关，第Ⅳ类基因在被子植物中与冷胁迫响应有关，第Ⅳ类基因在单子叶植物中与盐胁迫响应有关，第Ⅳ类基因在被子植物中与盐胁迫响应有关，第Ⅳ类基因在单子叶植物中与盐胁迫响应有关。真双子叶植物中的类群IV、类群V、类群VI和类群IX以及单子叶植物中的类群VI在响应阿坝处理中起关键作用;真双子叶植物中的类群IV和单子叶植物中的类群V和类群VI在响应生物胁迫中不可替代。本研究为进一步研究被子植物VQ基因的功能和进化奠定了基础。
VQ protein, contain a conserved and short FxxxVQxLTG amino acid sequence motif. Some VQ proteins play important roles in development process and abiotic/biotic stress in plants. However, there has not been a systematic study of the VQ family in plants. The results revealed that Group I genes are conserved in plant development in angiosperms; Group IV and Group X in eudicots and Group I, Group VI and Group VII in monocots are involved in drought response; Group I and Group IV are the most important groups and conservational in response to salt stress in eudicots but not in monocots; VQ genes in Group II and Group IV which responded to cold stress were overlapped in angiosperms; Group IV, Group V, Group VI and Group IX in eudicots and Group VI in monocots play key roles in response to ABA treatment; Group IV in eudicots while Group V and Group VI are irreplaceable in response to biotic stress in monocots. We propose that this study provides solid foundations for the investigation of the functions and evolution of VQ genes in angiosperms.
