Fungi belonging to the genus Induratia are endophytes that have received considerable attention because of the production of natural bioactive secondary metabolites, such as volatile compounds, with antimicrobial activity. In this study, we distinguished I. cofeana and Induratia sp. isolated from Cofea arabica in Brazil based on three-loci phylogeny, ITS, RPB2, and TUB2. The Induratia isolates showed high morphological plasticity and produced diferent volatile organic compounds, indicating that these compounds might not be correlated with their phylogenetic assignment. However, PLS-DA was able to discriminate Induratia isolates into three diferent clusters: one associated with I. cofeana and two with Induratia sp. Induratia isolates showed biofumigant activity against Botrytis cinerea with emphasis on I. cofeana (CML 4019), which inhibited the pathogenic fungus in postharvest strawberries. Nematicidal activity against Meloidogyne incognita was also observed in fltrates and volatile compounds produced by Induratia isolates. Moreover, we observed that I. cofeana (CML 4019) metabolites showed antibacterial activity against Staphylococcus aureus, Enterococcus faecalis, and E. faecium and that extracts of seven other Induratia isolates reduced the pre-formed bioflm of Staphylococcus aureus and Staphylococcus epidermidis. |

During April 1993 a nematode survey was conducted in an experimental are of Embrapa Cerrados, Planaltina, Federal District of Brazil, where 21 genotypes of sesame (Sesamum indicum L.) were sampled for nematode presence. Four composite soil and root samples were collected from the rhizospheres of cach genotype before harvest. The nematodes were extracted from 100g of soil and 10g of roots utilizing modified Coolen's method. Seven species of plant-parasitic nematodes, with decreasing frequency of occurence in genotypes were: Pratylenchus brachyurus (100%), Aphelenchoides sp. (100%), Ditylenchus sp. (100%), Helicotylenchus dihystera (67%), Paratrichodorus minor (67%) and Criconemella ornata (48%). Two species of mycophagos nematodes were found, and their frequency of occurrence in genotypes was: Aphelenchus avenae (100%) and Tylenchus sp. (95%). Free-living nematodes were present in all the samples. The average population densities of P. brachyurus varied between 3 per sample for genotype Aceiteira SN 2 and 56 for genotype Seridó 01 SM2; H. dihystera, Criconemella ornata e P. minor population densities/sample, when found, were present in very low numbers. |
