Complete Genome Sequences and Genome-Wide Characterization of Trichoderma Biocontrol Agents Provide New Insights into their Evolution and Variation in Genome Organization, Sexual Development, and Fungal-Plant Interactions
By Dr. Wang, Ting-Fang - December, 2021 Dec 2021 in Microbiology Spectrum工業用瑞氏木黴菌與4種農業用生物防治木黴菌的全基因體都有7條染色體。Trichoderma virens FT-333與Trichoderma asperellum FT-101是嘉義農業試驗分所倪蕙芳主任與嘉義大學生化科技學系陳瑞祥教授發現的台灣特有菌株。
Diagrammatic representations of the seven chromosomes of Trichoderma reesei CBS999.97(MAT1-2) [CBS1-2] (A), Trichoderma reesei QM6a (B), Trichoderma virens Gv29-8 (C), Trichoderma virens FT-333 (D), Trichoderma atroviride P1 (E), and Trichoderma asperellum FT-101 (F). For comparative genome analyses, we identified orthologous gene pairs using the annotation results generated by Funannotate v1.8 . The colors of chromosome fragments represent orthologous proteins consistent with their colors in CBS1-2 to clearly show chromosomal rearrangements. Locations of predicted centromeres are shown by restricted width. White fragments in QM6a, Gv29-8, FT-333, P1, and FT-101 represent strain-specific sequences that do not exist in CBS1-2, respectively. Locations of AT-rich blocks are indicated by black bars in the lower chromosomal maps. Black, white and gray arrows indicate disruption of synteny occurring at AT-rich blocks of the subject genomes, the CBS1-2 genome, or both, respectively.
