摘要:

目的 鉴定白菜型油菜(Brassia rapa L.)类胡萝卜素裂解双加氧酶(carotenoid cleavage dioxygenases, CCDs)基因家族成员,深入了解BrCCD家族基因功能及组织表达特性。 方法 利用生物信息学方法,对白菜型油菜CCDs基因家族进行鉴定,构建系统发育树,对其染色体分布、基因结构、保守基序、种内共线性及启动子顺式元件进行分析。结合转录组数据和RT-qPCR技术,分析CCDs基因在不同组织中的表达情况。 结果 在白菜型油菜中鉴定出16个 BrCCD基因,划分为6个亚组,不均匀的分布在8条染色体上;共线性分析发现有7对CCDs基因之间存在共线性关系;顺式作用元件分析表明,CCDs家族成员可能响应生长发育、激素调控、非生物胁迫等多种调控过程。转录组及定量PCR数据分析显示,BrCCD的表达具有组织特异性,BrCCD-L基因在花、叶和种子中表达量较高,BrCCD1b在花中表达量较高,其余多在种子和叶中具有较高的表达量。 结论 白菜型油菜基因组中共鉴定出16个CCDs基因,在不同组织中表现出不同的表达模式。BrCCD-L基因与藏红花属CCD2基因具有极高的相似性,且在不同组织中都显著表达。

Abstract:

Objective The members of the carotenoid cleavage dioxygenase gene family in Brassia rapa L. were identified to gain insight into the function and tissue expression characteristics of the BrCCD family genes. Method Bioinformatics methods were used to identify the CCDs gene family in B.rapa L., construct a phylogenetic tree, and analyze the chromosome distribution, gene structure, conserved motif, intraspecific collinearity and promoter cis elements. Combined with transcriptome data and RT-qPCR technology, the expression of CCDs genes in different tissues was analyzed. Result Total 16 BrCCD genes were identified in B.rapa L., which were divided into six subgroups and distributed unevenly on eight chromosomes. Colinearity analysis showed that there was a collinearity between seven pairs of CCDs genes. Cis element analysis showed that CCDs family members may respond to various regulatory processes such as growth and development, hormone regulation, and abiotic stress. Transcriptome and quantitative PCR data analysis showed that the expression of BrCCD was tissue-specific, and the expression of BrCCD-L gene was higher in flowers, leaves and seeds, BrCCD1b was higher in flowers, and the rest was higher in seeds and leaves. Result Total 16 CCDs genes were identified in the genome of B.rapa L., which showed different expression patterns in different tissues. The BrCCD-L gene was highly similar to the CCD2 gene with saffron genus, and was significantly expressed in different tissues.
