A Combined Analysis of Transcriptome and Proteome Reveals the Inhibitory Mechanism of a Novel Oligosaccharide Ester against Penicillium italicum.

ABSTRACT: Blue mold caused by Penicillium italicum is one of the most serious postharvest diseases of citrus fruit. The aim of this study was to investigate the inhibitory effect of a novel oligosaccharide ester, 6-O-β-L-mannopyranosyl-3-O-(2-methylbutanoyl)-4-O-(8-methyldecanoyl)-2-O-(4-methyl-hexanoyl) trehalose (MTE-1), against P. italicum. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM), along with transcriptome and proteome analysis also, were conducted to illuminate the underlying mechanism. Results showed that MTE-1 significantly inhibited P. italicum growth in vitro in a dose-dependent manner. Moreover, MTE-1 suppressed the disease development of citrus fruit inoculated with P. italicum. Furthermore,
