Project description:Penicillium citrinum X9-4, which was isolated from infected grapes by our laboratory, produced the highest amount of OTA at pH 5 in culture media, and toxin-production was restrained under acidic environment (pH 3). It revealed the possible mechanism of OTA biosynthesis and metabolic regulation in P. citrinum by transcriptomics, and investigated the reason of OTA biosynthesis was restrained in P. citrinum when cultured under acidic environment.
Project description:Penicillium digitatum is the pathogen of Green mold in Postharvest citrus. After inoculating Penicillium digitatum into the wound of citrus to infect it, transcriptome sequencing was carried out and compared with the results of transcriptome sequencing of Penicillium digitatum before inoculation in order to screen the differentially expressed genes and reveal its infection mechanism.
