摘要:

为探索山西连翘道地性形成的分子机制,基于连翘基因组数据,采用生物信息学方法对连翘UGT基因家族成员进行了全基因组鉴定和特征分析;并利用不同产地连翘转录组数据和实时荧光定量PCR技术分析了连翘UGTs基因在不同产地和不同组织中表达模式。结果表明,在连翘全基因组中共鉴定到170个家族成员,该家族成员不均匀地分布在14条染色体上,分别命名为FsUGT1~FsUGT170;其编码的蛋白分子质量为11.16~56.77 ku,等电点为4.70~9.18,其中,大多数为亲水性蛋白。亚细胞定位预测结果显示,FsUGTs蛋白主要定位于叶绿体和细胞质中。系统进化树分析发现,连翘UGT基因家族可划分为15个亚组;共线性分析发现,23个FsUGTs和拟南芥的20个UGTs组合形成31种共线性关系。基因结构、蛋白质基序和保守结构域分析显示,FsUGTs基因具有1~7个外显子和0~6个内含子,编码的蛋白均具有PSPG保守结构域。启动子顺式作用元件分析发现,FsUGTs基因启动子区域含有多个光响应、植物激素响应、生物和非生物胁迫以及生长发育相关等元件。基因表达模式分析发现,FsUGT4FsUGT145在山西连翘中的表达量显著高于河南和陕西,并在连翘叶中的表达量显著高于花和果实。综上,研究结果鉴定了170个连翘UGT基因家族成员,并筛选得到2个在山西连翘高表达并推测与连翘苷合成相关的基因FsUGT4FsUGT145

Abstract:

To explore the formation molecular mechanism of the geoherbalism of Shanxi Forsythia suspensa,a genome-wide identification and characterization of UGT gene family members was performed using bioinformatics methods based on the genome data of F.suspensa.Transcriptome data of F.suspensa from different producing areas and Real-time PCR were used to analyze the expression patterns of UGTs gene in F.suspensa from different habitats and different tissues.The results showed that a total of 170 family members were identified in the whole genome of F.suspensa,and the family members were unevenly distributed on 14 chromosomes,named as FsUGT1FsUGT170.The molecular weight of 11.16—56.77 ku and isoelectric point of 4.70—9.18,most of which are hydrophilic proteins.Subcellular localization predictions indicated that FsUGT proteins were predominantly localized in the chloroplast and cytoplasm.Phylogenetic analysis classified the F.suspensa UGT gene family into 15 distinct subgroups.Synteny analysis identified 31 collinear gene pairs involving 23 FsUGTs and 20 UGTs from Arabidopsis thaliana.Analysis of gene structure,conserved protein motifs,and conserved domains revealed that the FsUGT genes possess 1 to 7 exons and 0 to 6 introns,and all encoded proteins contain the characteristic PSPG conserved domain.Promoter cis-acting element analysis demonstrated the presence of multiple regulatory elements associated with light responsiveness,phytohormone signaling,biotic and abiotic stress responses,and growth and development within the promoter regions of FsUGT genes.Gene expression profiling showed that the transcript levels of FsUGT4 and FsUGT145 were significantly higher in F.suspensa samples from Shanxi compared to those from Henan and Shaanxi,and their expression in leaves was significantly higher than in flowers and fruits.In conclusion,this study identified 170 members of the UGT gene family in F.suspensa and highlighted two genes,FsUGT4 and FsUGT145,which exhibit elevated expression in Shanxi accessions and are potentially implicated in forsythin biosynthesis.
