Comparative analysis of transcriptome in leaves of Ageratina adenophora and Ageratum conyzoides
摘要
Abstract
Ageratina adenophora(Sprengel)R.M.King&H.Rob.and Ageratum conyzoides L.are significant Asteraceae species characterized by both invasiveness and medicinal value.Elucidating the logical connections between the genetic backgrounds of these two species and their biological traits is crucial for revealing the underlying mechanisms of their ecological evolutionary advantages and the material basis of their medicinal properties.In this study,transcrip-tome sequencing of leaf tissues was conducted to characterize the genetic drivers supporting these biological characteristics at the molecular level.The results showed that 40 284 252 and 46 478 924 raw reads were obtained for A.adenophora and A.conyzoides,respectively,with assembled Unigene lengths primarily concentrated between 200-300 bp.Logical correlation analysis between the omics data and biological phenotypes revealed that clusters of orthologous groups for eu-karyotic complete genomes annotations for both species were highly enriched in signal transduction mechanisms,provid-ing molecular support for their robust environmental sensing and stress response capabilities.Furthermore,the higher pro-portion of genes in this pathway in A.adenophora is consistent with its broader geographic expansion potential.Regard-ing medicinal value,A.conyzoides exhibited superior enrichment in flavonoid biosynthesis pathways and catalytic gene abundance compared to A.adenophora,validating its phenotypic advantages in anti-inflammatory efficacy at the molecu-lar level.Additionally,significant enrichment in sesquiterpenoid and triterpenoid biosynthesis pathways elucidates the ge-netic background underlying the use of allelochemicals for invasive colonization in both species.Simple sequence repeat(SSR)analysis indicated that A.adenophora possesses higher polymorphism potential,which is closely related to its strong habitat adaptability.By deciphering biological functional connotations through transcriptome data analysis,this study provides critical evidence for further investigation into invasive mechanisms and medicinal resource exploitation.关键词
