The volatile compound (E)-2-hexenal in wampee (Clausena lansium) represses the development of Penicillium italicum and enhances the disease resistance of postharvest citrus fruit
Wampee (Clausena lansium) is a relative of cultivated citrus in the Rutaceae family. Its cracked fruit in orchard is not susceptible to Penicillium italicum infection, but the mechanism remains unknown. In this study, it was found that the volatiles from wampee leaf (WL) and wampee pericarp (WP) can repress the infection and development of P. italicum in vitro. Additionally, WL exhibited strong antifungal effects in in vivo experiments as well. Antifungal activity analysis of WL volatile organic compounds (VOCs) demonstrated that (E)-2-hexenal is the key antifungal compound against P. italicum by disrupting the integrity of cell membrane. Moreover, exogenous (E)-2-hexenal treatment significantly reduced the area covered by mycelia on citrus fruits and increased the expression of genes and accumulation of various metabolites related to disease resistance. These results indicate that WL can be used as a promising natural preservative in citrus postharvest handling mainly due to the antifungal activity of (E)-2-hexenal.
期刊介绍：
The journal is devoted exclusively to the publication of original papers, review articles and frontiers articles on biological and technological postharvest research. This includes the areas of postharvest storage, treatments and underpinning mechanisms, quality evaluation, packaging, handling and distribution of fresh horticultural crops including fruit, vegetables, flowers and nuts, but excluding grains, seeds and forages.
Papers reporting novel insights from fundamental and interdisciplinary research will be particularly encouraged. These disciplines include systems biology, bioinformatics, entomology, plant physiology, plant pathology, (bio)chemistry, engineering, modelling, and technologies for nondestructive testing.
Manuscripts on fresh food crops that will be further processed after postharvest storage, or on food processes beyond refrigeration, packaging and minimal processing will not be considered.
