番茄CKX基因家族生物信息学分析

植物细胞内的细胞分裂素受到细胞分裂素脱氢酶/氧化酶(Cytokinin oxidase/dehydrogenase,CKX)的调节,来维持植物体内细胞分裂素动态平衡。为探究番茄基因组中CKX基因(SlCKX)家族成员的信息,本研究通过现代生物信息学分析,对番茄中CKX基因家族进行鉴定和分析。结果表明,在番茄全基因组中鉴定出9个CKX基因家族成员,蛋白长度在453~553氨基酸之间,编码蛋白分子量在51660.72~52493.64kDa之间,为亲水性蛋白；番茄CKX基因分在4个亚族内,并且SlCKX家族成员中含有3~5的内含子以及4~6外显子；9个番茄CKX家族基因不均匀的分布在5条染色体上,番茄CKX基因家族包含11种顺式作用元件,其中分布最广的为脱落酸响应元件。该研究将为番茄CKX基因家族的功能和应用研究提供一定的理论依据。

Bioinformatics analysis of CKX gene family in Tomato

Cytokinin in plant cells is regulated by cytokinin oxidase/dehydrogenase (CKX) to maintain cytokinin homeostasis in plants. In order to explore the information of CKX gene (SlCKX) family members in the tomato genome, this study identified and analyzed the CKX gene family in tomato through modern bioinformatics analysis. The results showed that 9 members of the CKX gene family were identified in the whole tomato genome, the protein length was between 453 and 553 amino acids, and the encoded protein molecular weight was between 51660.72 and 52493.64 kDa, which were hydrophilic proteins. In this subfamily, and members of the SlCKX family contain 3-5 introns and 4-6 exons; 9 tomato CKX family genes are unevenly distributed on 5 chromosomes, and the tomato CKX gene family contains 11 cis The most widely distributed is the abscisic acid-responsive element. This study will provide a theoretical basis for the research on the function and application of the tomato CKX gene family.
