Summary: Meyerozyma caribbica has shown potential as an antagonistic yeast in controlling postharvest blue mold of kiwifruit. It can significantly reduce disease incidence, inhibit the growth of Penicillium expansum, and induce disease resistance in fruits. The yeast shows strong adaptation to the environment and competes with pathogens for nutrients and space. Additionally, it increases antioxidant enzyme activities and secondary metabolite contents in fruits.

Summary: Adding different concentrations of GlcNAc during the culture of Rhodosporidium paludigenum can reduce the incidence of pears caused by Penicillium expansum, with 0.1% GlcNAc being the optimal concentration. The cultivated R. paludigenum after GlcNAc induction showed exceptional impact in restraining P. expansum on pears and exhibited vigor under various stress conditions. Additionally, the enzyme activity and gene expression levels of antioxidant-related enzymes in R. paludigenum were up-regulated, with low levels of reactive oxygen species observed.

Summary: In this study, a yeast strain, Hannaella sinensis, was selected for its good control effect on blue mold decay in apples. The research aimed to investigate the biocontrol effect of H. sinensis on blue mold decay in apples and the underlying mechanisms. The results demonstrated that H. sinensis effectively controlled blue mold decay in apples and inhibited the germination of spores and growth of germ tubes of P. expansum. Furthermore, H. sinensis colonized apple wounds and surfaces, showing its environmental adaptability and ability to compete for resources with other microbiota. Additionally, H. sinensis induced the activities of resistance-related enzymes and the expression of corresponding genes in apples, leading to enhanced disease resistance. Overall, H. sinensis showed great potential as an antagonistic yeast for the prevention and treatment of postharvest blue mold decay in apples.

Summary: This study found that GlcNAc significantly improved the antagonistic efficacy of Kluyveromyces marxianus against Penicillium expansum by increasing biocontrol-related enzymes and stress-resistant substances. GlcNAc also enhanced the antioxidative-related enzyme activities and proliferative capacity of K. marxianus, contributing to its environmental adaptability and stress resistance.

Summary: This study investigated the effect of cinnamon essential oil (CEO) loaded in nanostructured lipid carriers (NLC) on the decay of tangerines caused by Penicillium citrinum and Penicillium expansum. The CEO-loaded NLC showed potential in reducing weight loss and inhibiting fungal growth, making it a possible treatment for increasing tangerine shelf life.

Summary: This study investigates two Penicillium chrysogenum isolates as potential biocontrol agents against Penicillium expansum in apples. The results show that these isolates can effectively reduce decay incidence and severity in apples, without showing antagonism with Penicillium expansum. These findings contribute to the development of novel decay intervention strategies for managing postharvest diseases.

Summary: Botrytis cinerea and Penicillium expansum are the most important postharvest pathogens of apples. This study found that ozone (O-3) and carbon dioxide (CO2) treatments combined with specific yeast isolates can effectively control blue and gray molds of apples. However, using yeast combined with O-3 was less effective in disease control compared to using yeast combined with CO2. Although CO2 or O-3 treatments alone resulted in decreased apple quality after storage, with O-3 causing necrotic spots on fruits.

Summary: Pine wilt disease caused by the nematode Bursaphelenchus xylophilus is highly damaging to East Asian pine forests. In this study, the response of PWN-resistant and -susceptible P. thunbergii to PWN inoculation was analyzed at the transcriptional level. Differential gene expression analysis revealed distinct strategies employed by the resistant and susceptible P. thunbergii in dealing with PWN infections. The results shed light on the mechanisms underlying resistance and susceptibility to PWN in P. thunbergii.
