Insights on the Evolution of Mycoparasitism from the Genome of Clonostachys rosea

摘要: Clonostachys rosea is a mycoparasitic fungus that can control several important plant diseases. Here, we report on the genome sequencing of C. and comparative analysis, in order to resolve phylogenetic placement study evolution mycoparasitism as fungal lifestyle. The estimated 58.3 Mb, contains 14,268 predicted genes. A phylogenomic analysis shows clusters sister taxon pathogenic Fusarium species, with mycoparasitic/ saprotrophic Trichoderma species an ancestral position. gene family reveals distinct differences between included mycoparasites. significantly more ATP-binding cassette (ABC) transporters, polyketide synthases, cytochrome P450 monooxygenases, pectin lyases, glucose-methanol-choline oxidoreductases, lytic polysaccharide monooxygenases compared other fungi Hypocreales. Interestingly, increase ABC transporter number associated subgroups B (multidrug resistance proteins) G (pleiotropic drug transporters), whereas subgroup C resistance-associated evident virens .I n contrast very few chitinases. Expression six group genes was induced during exposure mycotoxin zearalenone, fungicide Boscalid or metabolites from biocontrol bacterium Pseudomonas chlororaphis. data suggest tolerance toward secondary prominent feature biology rosea.
