“…The results on the biocontrol revealed that the H. uvarum cells pre‐treated with the trehalose effectively reduced grape rot caused by A. tubingensis strain M1 and P. commune V5–1. The increase in the biocontrol efficacy of H. uvarum may be ascribed to the increase in the defense‐related enzymes of the grape . These results are similar to those of Zhao et al .…”

“…Apparently, the 2% w/v trehalose, H. uvarum, and H. uvarum that was enhanced with the trahalose significantly reduced fungal spore germination in PDB compared with the control. In a previous study, the conidia of A. tubingensis in grape wounds treated with H. uvarum enhanced with 2% w/v trehalose was significantly reduced compared to the other treatments . The results showed that the trehalose may have enhanced the viability of the H. uvarum .…”

“…Our previous results also demonstrated that H. uvarum was effective against A. tubingensis in grapes. 15 Trehalose, chitinase, phosphatidylcholine, salicylic acid, and several other natural compounds have been used alone as bio protectors or in combination with microbial antagonists to control the postharvest diseases of fruits. 16 Most of these bioactive compounds have been reported to induce defense-related activities and antioxidant enzymes in fruits.…”

BACKGROUND In the process of biological control, the antagonistic yeasts contend with various stresses that negatively influence yeasts' biocontrol efficiency. In the current study, we investigated the effect of trehalose supplementation on the biocontrol efficiency and oxidative stress tolerance of Sporidiobolus pararoseus Y16. RESULTS S. pararoseus Y16, an antagonistic yeast cultured in trehalose supplemented medium, exhibited better biocontrol efficiency against Penicillium expansum and Aspergillus tubingensis in table grapes. Trehalose‐treated S. pararoseus Y16 cells showed good proliferation efficiency and oxidative stress tolerance than untreated cells. Increased β‐1,3‐glucanase, catalase, superoxide dismutase activity, and low protein carbonylation were observed in trehalose‐amended S. pararoseus Y16 upon H2O2 exposure. The RNA sequencing results indicated that trehalose significantly altered the transcriptome of S. pararoseus Y16. The GO, KEGG, and COG annotations revealed that the differentially regulated genes corresponded to the various biological process of the yeast. CONCLUSION Our findings suggested that trehalose use could enhance the biocontrol efficiency and oxidative stress tolerance of S. pararoseus Y16. Trehalose supplementation altered the transcriptome of S. pararoseus Y16, particularly the genes that correspond to amino acid metabolism, nucleotide metabolism, and protein modification. Thereby the oxidative stress tolerance and biological control efficiency of S. pararoseus Y16 was enhanced by trehalose. © 2021 Society of Chemical Industry.
