is a parasitic herbaceous plant that obtains nutrients by forming specialized structures called haustoria to invade host plants.
In this study, we elucidated the differences in the gene expression regulation and metabolic characteristics between and ( (L.) ) through comprehensive transcriptomic and metabolomic analyses.
The results demonstrated significant differences in the gene expression and metabolic features between the haustorium and the distal stem segments. The differentially expressed genes absorbed by from the soybean host influence amino acid metabolism, and the expression of the S-adenosylmethionine decarboxylase gene may affect the production of 5'-methylthioadenosine. A high expression of the chalcone synthase enzyme could lead to an increased daidzein content. Many genes were also integrated into within the haustorium.
This study systematically analyzed, for the first time, the significant differences in gene expression and metabolic characteristics between the haustoria and distal stem segments of . It also explored the nutrient absorption mechanisms of the host plant. Additionally, the research discovered that can absorb a substantial amount of host genes and adapt to its parasitic lifestyle through differential gene expression and metabolic changes. These findings provide important insights into the parasitic mechanisms of and lay the foundation for the development of effective control strategies.
[植物名称]是一种寄生草本植物，通过形成称为吸器的特殊结构侵入宿主植物来获取营养。
在本研究中，我们通过全面的转录组学和代谢组学分析，阐明了[植物名称]吸器与茎段远端在基因表达调控和代谢特征上的差异。
结果表明，吸器与茎段远端在基因表达和代谢特征上存在显著差异。[植物名称]从大豆宿主吸收的差异表达基因影响氨基酸代谢，S -腺苷甲硫氨酸脱羧酶基因的表达可能影响5'-甲硫基腺苷的产生。查尔酮合酶的高表达可能导致大豆苷元含量增加。许多[植物名称]基因也整合到吸器内。
本研究首次系统分析了[植物名称]吸器与茎段远端在基因表达和代谢特征上的显著差异。还探索了宿主植物的营养吸收机制。此外，研究发现[植物名称]可以吸收大量宿主基因，并通过差异基因表达和代谢变化适应其寄生生活方式。这些发现为[植物名称]的寄生机制提供了重要见解，并为制定有效的控制策略奠定了基础。
