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.
Project description:As part of our investigations on the chemical diversity of organisms from unexplored marine habitats of Mexico, a series of 29 fungal strains isolated from deep-sea sediments (more than 600 m deep) from the Gulf of Mexico were investigated. The antimicrobial potential of their organic extracts from solid cultures grown under the OSMAC approach was assessed against a panel of ESKAPE bacteria and the yeast C. albicans. Chemical studies on the active scaled-up cultures and some small-scale cultures led to the isolation of benzochromenones from Alternaria sp. CIGOM4, benzodiazepines from P. echinulatum CONTIG4, a cytochalsin from Biatriospora sp. CIGOM2, and an imidazopyridoindole from Penicillium sp. CIGOM10. Molecular network analysis by GNPS combined with manual dereplication showed the enormous potential of these fungi to produce bioactive compounds.
Project description:In Aspergillus sp., BrlA is a master transcription factor essential for the induction of conidiogenesis. Sometimes it is also involved in the secondary metabolism. The aim of this study was to characterize the role of BrlA in Penicillium expansum. For that a null mutant PeΔBrlA was generated.
Project description:Comparative analysis of transcriptome of Penicillium marneffei PM1 grown at 25°C and 37°C Penicillium marneffei strain PM1 was pre-cultured at 25°C and 37°C for two weeks on Sabouraud's Dextrose Agar (SDA). Messenger RNAs were then isolated from one-week 25°C and 37°C cultures and sequenced with Illumina by BGI America. Two replicates.
