Abstract
Pestalotiopsis sp. is a mycoparasite of the plant pathogen Aecidium wenshanense. To further understand the mycoparasitism mechanism of Pestalotiopsis sp., we assembled and analyzed its genome. The genome of Pestalotiopsis sp. strain PG52 was assembled into 335 scaffolds and had a size of 58.01 Mb. A total of 20,023 predicted genes and proteins were annotated. This study compared PG52 with the mycoparasites Trichoderma harzianum, Trichoderma atroviride, and Trichoderma virens. This study reveals the entirely different mycoparasitism mechanism of Pestalotiopsis compared to Trichoderma and reveals this mycoparasite's strong ability to produce secondary metabolites.
