摘要:
为了研究甜瓜(Cucumis melo L.)GRAS基因家族的结构特征、进化模式和生长发育过程中的表达模式，对甜瓜GRAS全基因组的基本信息、染色体位置、共线性、系统发育树、基因结构、表达模式、顺式元件进行了全面分析。结果表明，从甜瓜中鉴定出37个GRAS基因；这些基因在甜瓜的11条染色体上呈不均匀分布，并在6、7、8号染色体上出现串联重复；甜瓜GRAS家族可分为HAM、LS、SCR、SCL3、DELLA、LISCL、SHR、PAT1 8个亚族；基因结构分析显示，含有1～3个内含子的基因有8个，没有内含子的基因有29个；启动子分析，鉴定到生长素、脱落酸、赤霉素、低温、干旱、光信号响应作用元件以及参与分生组织和胚乳表达的元件；表达模式分析结果表明，HAM、DELLA亚族的基因几乎在所有组织中都有表达，LS亚族在根和茎中表达含量较高，PAT1亚族在甜瓜的整个生长发育过程中发挥着重要作用。得出结论，甜瓜全基因组共获得GRAS基因 37 个，共可分为8个亚族，不同的亚族具有不同的基因结构、蛋白质结构和表达模式；不同亚族在甜瓜生长发育的不同阶段具有差异性表达，它们共同参与调控甜瓜的发育过程。
