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:Five new pyran rings containing polyketides, penicipyrans A-E (1-5), together with the known pestapyrone A (6), were isolated from the saline soil-derived Penicillium raistrickii. Their structures were determined by interpretation of NMR and HRESIMS data. The absolute configurations of compounds 4 and 5 were established by the modified Mosher's method and single-crystal X-ray diffraction analysis, respectively. These compounds possessed high structural diversity including two ?-pyrones (1, 2), three isocoumarins (3, 4, 6), and one dihydropyran derivative (5). Among them, Compound 5 exhibited cytotoxicity against HL-60 and K562 cell lines with IC50 values of 4.4 and 8.5 ?M, respectively.
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.
Project description:RNA-seq was used to compare differential gene expressions for Penicillium oxalicum wild type strain (M12) and sporognesis related genes knock out strains.The goals of this study are to construct the sporogenesis regulation pathway of Penicillium oxalicum. Examination of differential gene expressions by digital gene expression tag profiling in Penicillium oxalicum wild type strain and nine mutant strains (flbA knoutout strain, flbB knoutout strain, flbC knoutout strain, flbD knoutout strain, flbE knoutout strain,wetA knoutout strain, abaA knoutout strain,stuA knoutout strain, swi6 knoutout strain)
