(Thunb.) Breit. (Araceae), a significant medicinal plant, has been used to treat various diseases for centuries. Terahertz radiation (THZ) is located between microwaves and infrared rays on the electromagnetic spectrum. THZ possesses low single-photon energy and a spectral fingerprint, but its effects on plant growth have not yet been investigated. The study's primary objective was to examine the transcriptome and metabolome databases of the SY line to provide a new perspective for identifying genes associated with resistance and growth promotion and comprehending the underlying molecular mechanism. Variations in the biological characteristics of grown under control and experimental conditions were analyzed to determine the effect of THZ. Compared with the control group, phenotypic variables such as leaf length, petiole length, number of leaves, leaf petiole diameter, and proliferation coefficient exhibited significant differences. response to THZ was analyzed regarding the effects of various coercions on root exudation. The experimental group contained considerably more sugar alcohol than the control group. The transcriptome analysis revealed 1,695 differentially expressed genes (DEGs), including 509 upregulated and 1,186 downregulated genes. In the KEGG-enriched plant hormone signaling pathway, there were 19 differentially expressed genes, 13 of which were downregulated and six of which were upregulated. In the metabolomic analysis, approximately 416 metabolites were uncovered. There were 112 DEMs that were downregulated, whereas 148 were upregulated. The leaves displayed significant differences in phytohormone metabolites, specifically in brassinolide (BR) and abscisic acid (ABA). The rise in BR triggers alterations in internal plant hormones, resulting in faster growth and development of . Our findings demonstrated a link between THZ and several metabolic pathway processes, which will enhance our understanding of mechanisms.
（天南星科）白星海芋，一种重要的药用植物，几个世纪以来一直被用于治疗各种疾病。太赫兹辐射（THZ）位于电磁光谱中的微波和红外线之间。太赫兹具有低单光子能量和光谱指纹，但尚未研究其对植物生长的影响。该研究的主要目的是检查SY系的转录组和代谢组数据库，为鉴定与抗性和生长促进相关的基因以及理解潜在的分子机制提供新的视角。分析了在对照和实验条件下生长的生物学特性变化，以确定太赫兹的影响。与对照组相比，叶长、叶柄长度、叶片数量、叶柄直径和增殖系数等表型变量表现出显著差异。分析了对太赫兹的响应，涉及各种胁迫对根系分泌物的影响。实验组中的糖醇含量比对照组多得多。转录组分析揭示了1695个差异表达基因（DEG），包括509个上调基因和1186个下调基因。在KEGG富集的植物激素信号通路中，有19个差异表达基因，其中13个下调，6个上调。在代谢组分析中，发现了约416种代谢物。有112种差异表达代谢物下调，而148种上调。白星海芋叶片在植物激素代谢物方面表现出显著差异，特别是在油菜素内酯（BR）和脱落酸（ABA）方面。BR的增加引发植物内部激素的变化，导致白星海芋生长和发育加快。我们的研究结果表明太赫兹与几个代谢途径过程之间存在联系，这将增进我们对白星海芋机制的理解。
