Abstract

Xylona heveae (Xylonomycetes, Ascomycota) has only been isolated as an endophyte of rubber trees, Hevea brasiliensis. In an effort to understand the genetic basis of fungal endophytism, we compared the genome contents of X. heveae and 36 other Ascomycota with diverse lifestyles and nutritional modes, including other endophytes. We focused on genes that are known to be important in the host-fungus interaction interface and that presumably have a role in determining the lifestyle of a fungus. We also used phylogenomic data to infer the higher-level phylogenetic position of the Xylonomycetes, and we mined ITS sequences from nucleotide databases to explore the taxonomic and ecological diversity of the group. The X. heveae genome contains a low number of enzymes needed for plant parasitism or saprotrophy, suggesting that Xylona is a highly adapted specialist and likely dependent on its host for survival. The reduced repertoire of carbohydrate active enzymes could reflect an adaptation to intercellulary growth and to the avoidance of the host's immune system, suggesting that Xylona has a strict endophytic lifestyle. Phylogenomic data resolved the position of Xylonomycetes as sister to Lecanoromycetes and Eurotiomycetes and placed the beetle-endosymbiont Symbiotaphrina as a member of this class. ITS data revealed that Trinosporium is also part of the Xylonomycetes, extending the taxonomic and ecological diversity of this group.
