In conclusion, we explored the biodiversity of the endophytic community
in the medicinal plant V. divergens, found in a unique wetland in Brazil, the
Pantanal. Based on the number and richness of isolates, these organisms
showed preferential colonization in the dry period. We report, for the first
time, the identification of isolates of the genera Antrodia and Irpex as
endophytes, as well as describe many isolates that need to be better
characterized, with the potential for new species. In addition, three isolates
belonging to the family Xylariaceae and genus Nigrospora showed promising
results in the biological control of CBS. Studies on the biodiversity of
endophytic microorganisms are important to increase our knowledge of the
biodiversity in Brazil, as well as to discover new species for environmental
and industrial purposes.
