水果和蔬菜极易腐烂，收获后很容易失去商业价值。人们已经开发了不同的策略来控制采后腐烂并防止采后储存期间质量恶化，包括冷藏、气调（CA）以及生物和非生物刺激的应用。在这篇综述中，描述了与宿主侧和病原体侧的蛋白质水平反应相关的机制。已成功开发出针对顽固性、低蛋白质含量水果组织的蛋白质提取方案。比较蛋白质组分析和功能分析表明，防御相关蛋白质、能量代谢和抗氧化途径在水果响应储存条件和外源激发子处理方面发挥着重要作用。对病原真菌的分泌组进行了深入研究，结果表明水解酶是病原菌感染的关键毒力因子。这些蛋白质水平的变化为水果、病原体和环境条件之间的相互作用提供了新的线索。根据目前可用的蛋白质组数据，进一步提出了降低果实腐烂风险的潜在采后策略。
Fruits and vegetables are extremely susceptible to decay and easily lose commercial value after harvest. Different strategies have been developed to control postharvest decay and prevent quality deterioration during postharvest storage, including cold storage, controlled atmosphere (CA), and application of biotic and abiotic stimulus. In this review, mechanisms related to protein level responses of host side and pathogen side were characterized. Protein extraction protocols have been successfully developed for recalcitrant, low protein content fruit tissues. Comparative proteome profiling and functional analysis revealed that defense related proteins, energy metabolism, and antioxidant pathway played important roles in fruits in response to storage conditions and exogenous elicitor treatments. Secretome of pathogenic fungi has been well-investigated and the results indicated that hydrolytic enzymes were the key virulent factors for the pathogen infection. These protein level changes shed new light on interaction among fruits, pathogens, and environmental conditions. Potential postharvest strategies to reduce risk of fruit decay were further proposed based on currently available proteomic data.
