摘要:

为了解牡丹(Paeonia suffruticosa)中蔗糖非发酵(SNF)1-相关蛋白激酶(sucrose non-fermenting-1-related protein kinase,SnRK)基因家族成员及其特征,利用生物信息的方法对该家族成员进行了鉴定,共鉴定出22个PoSnRK基因,包括3个SnRK1、6个SnRK2和13个SnRK3CIPK)基因;保守结构域分析显示,所有PoSnRK1蛋白具有Pkinase、UBA和KA1结构域,PoSnRK2具有Pkinase结构域,PoCIPK具有Pkinase和NAF结构域;保守基序分析显示,Motif 15、Motif 17和Motif 18是SnRK1亚家族的特征基序,Motif 16和Motif 19是SnRK2的特征基序,Motif 7、Motif 10和Motif 14是CIPK的特征基序;共线性分析表明,PoSnRK基因间仅有1对共线性基因对Po04_CIPK10Po01_CIPK14;顺势作用元件分析发现大部分PoSnRK启动子区域具有响应激素以及转录因子结合的顺式作用元件;转录表达谱及qRT-PCR结果显示,Po02_SnRK2.8Po01_SnRK1.1Po01_CIPK6Po04_CIPK10的表达与牡丹花衰老过程相符,推测这四个基因在牡丹花衰老过程中发挥作用。

Abstract:

To investigate the members and characteristics of sucrose non-fermenting-1-related protein kinase(SnRK)gene family in Paeonia suffruticosa,bioinformatics methods were employed to identify the members,resulting in the identification of 22 PoSnRKs,including 3 SnRK1s,6 SnRK2s,and 13 SnRK3sCIPKs);conserved domain analysis revealed that all PoSnRK1 proteins possessed the Pkinase,UBA,and KA1 domains,PoSnRK2s possessed the Pkinase domain,and PoCIPKs possessed the Pkinase and NAF domains;conserved motif analysis identified Motif 15,Motif 17,and Motif 18 as characteristic motifs of the SnRK1 subfamily,Motif 16 and Motif 19 as characteristic motifs of the SnRK2 subfamily,and Motif 7,Motif 10,and Motif 14 as characteristic motifs of the CIPK subfamily. Collinearity analysis indicated that there was only one pair of collinear PoSnRKsPo04_CIPK10 and Po01_CIPK14cis-acting element analysis found that most PoSnRK promoters contained cis-elements responsive to hormones and transcription factor binding. Transcriptome expression profiles and qRT-PCR results showed that the expression level of Po02_SnRK2.8Po01_SnRK1.1Po01_CIPK6 and Po04_CIPK10 was consistent with the flower senescence,suggesting that these four genes played a role in the flower aging process of tree peony.
