摘要:
钙调磷酸酶B样蛋白互作蛋白激酶(CIPK)是一种重要的Ca2+信号传感器,在植物应答逆境非生物胁迫过程中发挥着重要作用。为了探究高粱中CIPK家族基因的功能,本研究从高粱基因组中鉴定了31个SbCIPK基因,这些基因不均匀地分布在高粱的9条染色体上,编码蛋白质的氨基酸数量为403～519个,等电点为6.07～9.38,相对分子质量为46 357.31～58 316.97。基因结构分析结果表明,SbCIPK家族基因分为内含子缺失型和内含子富集型2类。进化树分析结果表明,SbCIPK家族蛋白质成员分为8个亚族。基于转录组数据的表达模式分析结果表明,SbCIPK基因广泛参与对盐胁迫、干旱胁迫等非生物胁迫的响应。本研究结果可以为高粱CIPK家族基因的功能研究奠定基础。
Abstract:
Calcineurin B-like proteins interacting protein kinase (CIPK) is an important Ca2+ signal sensor, which plays an important role in plants’ response to abiotic stress. In order to explore the function of CIPK family gene members in Sorghum bicolor’ a total of 31 SbCIPK genes were identified, which were unevenly distributed on nine chromosomes from Sorghum bicolor in this study. The length of the SbCIPKs encoded proteins ranged from 403 to 519 aa, the isoelectric points ranged from 6.07 to 9.38, and the relative molecular weights ranged from 46 357.31 to 58 316.97. The SbCIPK gene family members were divided into intron deletion type and intron enrichment type by gene structure analysis. According to the results of phylogenetic tree analysis, the S. bicolor SbCIPK family protein members were divided into eight subgroups. SbCIPK genes were widely involved in abiotic stress responses to salt and drought and so on based on the published transcriptome data. These results can lay the foundation for the functional study of SbCIPK family members in S. bicolor.
