Assessing the Biocontrol Potential of Clonostachys Species Isolated as Endophytes from Coffea Species and as Mycoparasites of Hemileia Rusts of Coffee in Africa.

ABSTRACT: During surveys conducted in South America and Africa to identify natural fungal enemies of coffee leaf rust (CLR), Hemileia vastatrix, over 1500 strains were isolated, either as endophytes from healthy tissues of Coffea species or as mycoparasites growing on rust pustules. Based on morphological data, eight isolates-three isolated from wild or semiwild coffee and five from Hemileia species on coffee, all from Africa-were provisionally assigned to the genus Clonostachys. A polyphasic study of their morphological, cultural and molecular characteristics-including the Tef1 (translation elongation factor 1 alpha), RPB1 (largest subunit of RNA polymerase II), TUB (β-tubulin) and ACL1 (ATP citrate lyase) regions-confirmed these isolates as belonging to three species of the ge
