[Abstract]  Penicillium expansum, a widespread filamentous fungus, is a major causative agent of fruit decay and leads to huge economic losses during postharvest storage and shipping. Furthermore, it produces mycotoxin on the infected fruits that may cause harmful effects to human health. This pathogenicity assay involves a stab inoculation procedure of P. expansum on apple fruit, an important experimental technique to study fungal pathogenesis. This assay can be applied to analyze the virulence of postharvest pathogen on other fruits such as orange, pear and kiwifruit. [摘要]  广泛的青霉菌是广泛的丝状真菌,是果实腐烂的主要致病因素,并在收获后储存和运输中导致巨大的经济损失。此外,它对感染的水果产生霉菌毒素,可能对人体健康造成有害影响。这种致病性测定涉及P的刺刺接种程序。膨化在苹果果实上,是一种重要的实验技术,用于研究真菌发病机制。该测定可用于分析其他水果如橙子,梨和猕猴桃的收获后病原体的毒力。

背景 青霉菌是一种破坏性的采后病原体,在采后处理和储存过程中,许多流行的水果如苹果和梨都会腐烂。造成重大的社会经济影响,对国际贸易产生影响。病原体也可能导致严重的人体健康问题,因为它会产生有毒的次级代谢物,包括patulin,citrinin和球形青霉素(Andersen等,2004)。控制由P引起的腐蚀。膨胀对于确保各种水果的质量和安全性至关重要。
  &nbspConidia的 P。膨胀通常通过创伤进入,这是为提供病原体开发起点所必需的(Spotts等人,1998)。 P的致病性通常通过针刺接种来测试果实上的膨胀,其也用于灰葡萄孢与番茄相比,桃花生的致病性测定, 与芒果,相关的小菜蛾(Colletotrichum gloeosporioides) (Liu等人,2012; Shi等人,2012; ...
