Bacillomycin D-C16 can induce resistance in cherry tomato against pathogens; however, the underlying molecular mechanism is poorly understood. Here, the effect of Bacillomycin D-C16 on induction of disease resistance in cherry tomato was investigated using a transcriptomic analysis.
Transcriptomic analysis revealed a series of obvious enrichment pathways. Bacillomycin D-C16 induced phenylpropanoid biosynthesis pathways and activated the synthesis of defense-related metabolites including phenolic acids and lignin. Moreover, Bacillomycin D-C16 triggered a defense response through both hormone signal transduction and plant-pathogen interactions pathways, and increased the transcription of several transcription factors (e.g., AP2/ERF, WRKY and MYB). These transcription factors might contribute to the further activated the expression of defense-related genes (PR1, PR10 and CHI) and stimulated the accumulation of HO.
Bacillomycin D-C16 can induce resistance in cherry tomato by activating the phenylpropanoid biosynthesis pathway, hormone signal transduction pathway and plant-pathogen interactions pathway, thus activating comprehensive defense reaction against pathogen invasion. These results provided a new insight into the bio-preservation of cherry tomato by the Bacillomycin D-C16.
杆菌霉素 D-C16 可诱导樱桃番茄对病原体产生抗性,但对其潜在的分子机制知之甚少。本研究采用转录组分析,探讨了 Bacillomycin D-C16 对樱桃番茄诱导抗性的影响。
转录组分析揭示了一系列明显的富集途径。Bacillomycin D-C16 诱导苯丙烷生物合成途径,并激活防御相关代谢物(如酚酸和木质素)的合成。此外,Bacillomycin D-C16 通过激素信号转导和植物-病原体相互作用途径引发防御反应,增加了几个转录因子(如 AP2/ERF、WRKY 和 MYB)的转录。这些转录因子可能有助于进一步激活防御相关基因(PR1、PR10 和 CHI)的表达,并刺激 HO 的积累。
Bacillomycin D-C16 通过激活苯丙烷生物合成途径、激素信号转导途径和植物-病原体相互作用途径,诱导樱桃番茄产生抗性,从而激活对病原体入侵的综合防御反应。这些结果为 Bacillomycin D-C16 对樱桃番茄的生物保鲜提供了新的见解。
