摘要: 生长素响应基因家族能调节植物体内生长素平衡和生长素信号途径。文章采用生物信息学方法检索获得葡萄(Vitisvinifera L.)基因组数据库中的生长素响应基因,通过分析其染色体定位、基因共线性和系统进化,发现葡萄基因组含有25个AUX_IAA基因、19个ARF基因、9个GH3基因、42个LBD基因。这些生长素响应基因不均匀分布在葡萄的19条染色体上,部分家族基因在染色体上形成基因簇。葡萄芯片数据结果表明,生长素响应基因在葡萄不同时期的果实和叶芽中均有表达,尤其在果实转色期、叶芽萌发或休眠期表达量急剧变化。研究结果为葡萄生长素响应基因在叶片和果实发育过程中的功能研究提供参考。

Abstract: The auxin response gene family adjusts the auxin balance and the growth hormone signaling pathways in plants. Using bioinformatics methods, the auxin-response genes from the grape genome database are identified and their chromosomal location, gene collinearity and phylogenetic analysis are performed. Probable genes include 25 AUX_IAA, 19 ARF, 9 GH3 and 42 LBD genes, which are unevenly distributed on all 19 chromosomes and some of them formed distinct tandem duplicate gene clusters. The available grape microarray databases show that all of the auxin-response genes are expressed in fruit and leaf buds, and significant overexpressed during fruit color-changing, bud break and bud dormancy periods. This paper provides a resource for functional studies of auxin-response genes in grape leaf and fruit development.
