Genetic variability in the endophytic fungus Guignardia citricarpa isolated from citrus plants Genet. Mol. Biol.
Glienke-Blanco,Chirlei; Aguilar-Vildoso,Carlos Ivan; Vieira,Maria Lúcia Carneiro; Barroso,Paulo Augusto Vianna; Azevedo,João Lúcio.
During some phases of of their life-cycle endophytic fungi colonize plants asymptomatically being found most frequently inside the aerial part of plant tissues. After surface disinfection of apparently healthy leaves from three varieties of mandarin orange and one tangor, and after incubation on appropriate culture medium, 407 fungal isolates were obtained, giving a total infection frequency of 81%. No fungal growth was observed from disinfected seeds, indicating that fungi are probably not transmitted via seeds. Of the fungal isolates, 27% belonged to the genus Guignardia, with 12 isolates being identified as Guignardia citricarpa Kiely, which is described as a citrus pathogen. The isolates were variable in respect to the presence of sexual structures and...

Identification and colonization of endophytic fungi from soybean (Glycine max (L.) Merril) under different environmental conditions BABT
Pimentel,Ida Chapaval; Glienke-Blanco,Chirlei; Gabardo,Juarez; Stuart,Rodrigo Makowiecky; Azevedo,João Lúcio.
A total of 297 endophytic fungi were isolated from 1728 leaf and stem fragments collected about twenty and forty days after germination from soybean (Glycine max (L.) Merril) plants grown in the field and a greenhouse. The fungi belonged to eight groups, six dematiaceous genera (Alternaria, Cladosporium, Chaetomium, Curvularia, Drechslera and Scopulariopsis) and the non-dematiaceous genera Acremonium, Aspergillus, Colletotrichum, Fusarium, Paecilomyces and Penicillium along with some Mycelia sterilia.. There were qualitative and quantitative differences in the type and number of isolates obtained from greenhouse and field-grown plants, with more isolates being obtained from the latter. No difference was found in the number of fungi isolated from leaves and...
