摘要
黄瓜(Cucumis sativus L.)是中国主要蔬菜作物之一,具有很高的经济价值。植物特有的IQ67结构域蛋白(SUN)家族成员是钙传感器的下游靶标,能够参与植物发育和基础防御反应。本研究通过黄瓜基因组新组装版本(v3.0),对黄瓜SUN基因家族成员进行了全基因组的鉴定和分析。结果表明,黄瓜SUN基因家族包含29个成员,编码的蛋白均含有保守的IQ67结构域。黄瓜SUN家族成员基因启动子区域含有多个响应激素和胁迫反应的顺式作用元件,通过分析公共已发表的转录组数据,本研究发现SUN家族基因可能在黄瓜果实生长发育及生物和非生物胁迫中起重要作用。研究结果为进一步了解SUN家族基因的功能提供了一定基础。
Cucumber(Cucumis sativus L.)plays an important role in the vegetable industry in China and has high economic value.Members of the plant-specific IQ67 domain protein(SUN)family are downstream targets of calcium sensors and are involved in plant development and basic defense responses.In this study,we identified and analyzed the whole genome of CsSUN family members in cucumber by new assembly of cucumber genome(v3.0).The results showed that the CsSUN family contains 29 members,and all the proteins encoded contain the conserved IQ67domain.There are many cis-elements responsive to phytohormones and botic and abiotic stresses in the promotor region of CsSUN family members.Through the analysis of the published transcriptomes,we found that some CsSUN genes may play important roles both in fruit growth and development and under biotic and abiotic stresses in cucumber.These results provide a basis for further understanding of the functions of CsSUN genes in cucumber.
