Resumo

from the endophyte and plant pathogen, and pathogen growth area was measured.The endophytic strains G-01, G-02, and G-03 were effective against Fusarium solani and Didymella bryoniae.The endophyte rDNA regions corresponding to internal transcribed spacer 1-5.8S-internal transcribed spacer 2 were sequenced, and the results were compared with sequences deposited in the NCBI database.The G-01, G-02, and G-03 strains were identified as Diaporthe citri.This identification was confirmed by phylogenetic analysis.The crude extract of the secondary metabolites of the G-01 strain was tested against Escherichia coli and Staphylococcus aureus; the metabolites showed antimicrobial activity against S. aureus.The endophytes tested in this study have potential for use in biotechnological applications.
