摘要:
芥子油苷(GS)是一类植物次生代谢产物,其多样性是由特定氨基酸前体延伸和侧链修饰所致。在侧链修饰过程中,AOP2和AOP3被证明可催化甲基亚磺酰基烷基GS分别形成烯基和羟烷基GS。为了解芥蓝(Brassica alboglabra)AOP基因家族成员编码2-氧化戊二酸双加氧酶的生物学功能,利用鉴定的家族成员进行蛋白质理化性质、蛋白质保守结构、基因结构、染色体定位、共线性关系、系统进化树、启动子顺式作用元件以及编码蛋白互作预测的生物信息学分析。结果显示,芥蓝中有17个AOP基因家族成员,蛋白质分子量为34 106.15-51 346.77,属酸性非分泌蛋白质,分布在6条染色体上;系统进化树分析结果显示,AOP基因家族可分为两大类;成员均包含DIOX_N和FE2OG_OXY结构域,Motif相对保守;成员启动子可能有多个转录起始位点,包含非生物胁迫应激响应元件及MYB结合位点,推测MYB可能通过调控AOP进而调控芥蓝GS代谢;AOP基因家族编码蛋白间不互作,与MYB、NDUF等蛋白互作;AOP家族成员间有3对共线性关系,与拟南芥基因组和芜菁基因组之间分别存在9对、20对共线性关系。本研究表明芥蓝17个AOP基因家族成员在功能上存在差异,且该家族成员参与光、多种激素信号和MYB转录因子复杂的调控网络,可为今后人工调控芥蓝GS组分和含量提供理论依据。(图7 表1 参50)
Abstract:
Glucosinolates (GS) comprise a class of plant secondary metabolites. Their diversity is caused by the elongation of specific amino acid precursors and modification of side chain. In the process of side chain modification, AOP2 and AOP3 were proved to catalyze the formation of alkenyl and hydroxyalkyl GS from methylsulfinyl alkyl GS, respectively. In order to understand the biological functions of 2-oxoglutarate dioxygenase encoded by members of the AOP gene family in Chinses kale (Brassica alboglabra). This paper used bioinformatics analysis to identify the members of the AOP gene family in Chinese kale. Bioinformatics analysis of protein physicochemical properties, protein conservative structure, gene structure, chromosomal localization, collinear relationship, phylogenetic tree, cis acting elements of promoter and coding protein interaction prediction were performed by using the identified family members. The results showed that there were 17 AOP gene members in Chinese kale. The protein molecular weights ranged from 34 106.15 to 51 346.77, which belonged to acidic non-secreted proteins and distributed on 6 chromosomes. According to phylogenetic tree analysis, they could be divided into two categories, and all members contained DIOX_N and FE2OG_OXY domains, motifs were relatively conservative. The member promoter sequences might contain multiple transcription start sites, including abiotic stress response elements and MYB binding sites, It was speculated that MYB may change the GS metabolism by regulating AOP. No effects were found for interaction among AOP gene family encoding protein, nevertheless there were other proteins interactions with them, namely MYB, NDUF, etc. There were 3 pairs of collinearity between the AOP family members, 9 pairs and 20 pairs of collinearity relations with arabidopsis genome and turnip genome respectively. The results showed that there were functional differences among the 17 AOP gene family members in Chinese kale, and the members of this family participated in the complex regulatory network of light, multiple hormone signals and MYB transcription factors, which provided theoretical basis for artificial regulation of GS components and content of Chinese kale in the future.
