由指状青霉引起的柑橘绿霉病是柑橘采后的常见病害。探讨其发病机理，将有助于研究和开发高效、安全的柑橘采后生物防治方法。本研究采用气相色谱-质谱仪(GC-MS)和液质联用仪(LC-MS)分析了柑橘网纹伤口处理前后的代谢产物。手足口病。结果表明，柑橘果实感染P.洋地黄。此外，结合以往的生理实验和转录组分析结果，对OFP基因进行了分析。通过对侵染前后柑橘伤口组织的观察，揭示了柑橘感染P。并对柑橘采后绿霉病的发病机制进行了探讨。通过这项研究，我们对OFP的机制提供了新的见解。为制定新的防治策略奠定了一定的基础。
Green mold caused byPenicillium digitatumis a common disease of postharvest citrus. Exploring its pathogenesis will contribute to the research and development of efficient and safe postharvest biological control methods for citrus. In this study, gas chromatography-mass spectrometry (GC-MS) and liquid chromatograph-mass spectrometer (LC-MS) were used to analyze the metabonomics ofCitrus reticulataBlanco wound before and afterP. digitatuminfection. The results showed that the metabolites such as carbohydrates, esters, organic acids, and resistance-inducing substances changed dramatically in the citrus wound after infection withP. digitatum. In addition, in combination with previous results from physiological experiments and transcriptome analysis ofP. digitatumbefore and after infection, we revealed the important changes of energy metabolism, protein hydrolysis process and defense response in the citrus wound after infection withP. digitatumand discussed the pathogenesis and mechanism of green mold disease after citrus harvest. From this study, we provided new insights into the mechanism ofP. digitatuminfection in postharvest citrus, which laid a certain foundation for the formulation of new control strategies.
