Relationship Between Host Acidification and Virulence of Penicillium spp. on Apple and Citrus Fruit

ABSTRACT Penicillium expansum, P. digitatum, and P. italicum acidify the ambient environments of apple and citrus fruit during decay development. They use two mechanisms for this: the production of organic acids, mainly citric and gluconic, and NH(4)(+) utilization associated with H(+) efflux. Expos... View More
