Resumo
In a plant-endophyte relationship, substances secreted
by microorganisms can help the plant to defend itself against
pathogens and also to promote an increase in biomass. This
study aimed to biochemically characterize endophytic fungi
from Bambusa oldhamii Munro, aiming at future studies on
plant growth promotion, as well as on resistance induction.
The following fungal isolates from B. oldhamii were used:
29 (Acrocalymma sp.); 122 (Botryobambusa fusicoccum);
711 (Phoma sp.); and 712 (Phoma sp.). Biochemical
characterization was performed, analyzing the production of
indole-acetic acid, chitinases and glucanases, as well as the
presence or absence of polyphenol oxidases and phosphate
solubilization activity in vitro. The isolate 29 produced
larger amounts of indole-acetic acid and chitinases, yielding
31.55 mg mL-1 after 96 h and 2.59 U mL-1 after 120 h,
respectively. The isolate 122 produced an increased amount
of glucanases, yielding 2.65 U mL-1 after 72 h. The isolates
29, 711 and 712 produced polyphenol oxidases. The isolate
711 showed phosphate solubilization activity in vitro. These
results indicate that the isolates under study show a potential
for inducing resistance in plants and for future studies on the
increase of plant biomass.
