  • Description: AbstractBackgroundMycoparasitism, a lifestyle where one fungus is parasitic on another fungus, has special relevance when the prey is a plant pathogen, providing a strategy for biological control of pests for plant protection. Probably, the most studied biocontrol agents are species of the genusHypocrea/Trichoderma.ResultsHere we report an analysis of the genome sequences of the two biocontrol speciesTrichoderma atroviride(teleomorphHypocrea atroviridis) andTrichoderma virens(formerlyGliocladium virens, teleomorphHypocrea virens), and a comparison withTrichoderma reesei(teleomorphHypocrea jecorina). These threeTrichodermaspecies display a remarkable conservation of gene order (78 to 96%), and a lack of active mobile elements probably due to repeat-induced point mutation. Several gene families are expanded in the two mycoparasitic species relative toT. reeseior other ascomycetes, and are overrepresented in non-syntenic genome regions. A phylogenetic analysis shows thatT. reeseiandT. virensare derived relative toT. atroviride. The mycoparasitism-specific genes thus arose in a commonTrichodermaancestor but were subsequently lost inT. reesei.ConclusionsThe data offer a better understanding of mycoparasitism, and thus enforce the development of improved biocontrol strains for efficient and environmentally friendly protection of plants.
