Medicinal plants represent a promising reservoir of diverse endophytic fungi, including taxa that are able to produce bioactive metabolites. In Brazil, the genus Copaifera includes species that are well known in folk medicine mainly due to their ability to produce oleoresin. In this study, we characterized the endophytic fungal communities associated with Copaifera langsdorffii and Copaifera pubiflora and investigated their ability to produce antimicrobial agents. We obtained 668 fungal isolates from the leaves, stems, and seeds of both plants, which were later classified into 64 taxa and 22 genera. Diaporthe sp. 6, Xylariaceae sp. 1, Diaporthales sp. 1, and Diaporthales sp. 2 were the most abundant taxa in C. langsdorffii, while Phyllosticta sp., Diaporthe sp. 7, Diaporthales sp. 3, and Diaporthe miriciae were the most abundant taxa in C. pubiflora. Diaporthe sp. 4, Phyllosticta sp., Diaporthe sp. 1, Diaporthe sp. 7, and Neopestalotiopsis sp. were the only taxa common between the two plants. Both plants were found to have high fungal diversity, especially C. langsdorffii. Six extracts displayed antibacterial, being Alternaria sp., Diaporthe sp. 1, D. miriciae, and Diaporthe sp. 14. Our results showed that different tissues of the ethnomedicinal plants C. langsdorffii and C. pubiflora are systematically colonized by rich and diverse endophytic fungal communities, and that some of the fungi are able to produce antimicrobial compounds, which may be explored in further studies as potential candidates for the development of new drugs.

ABSTRACT: The objectives of this work were to study the genetic control of grain yield (GY) and nitrogen (N) use efficiency (NUE, grain yield/N applied) and its primary components, N uptake efficiency (NUpE, N uptake/N applied) and N utilization efficiency (NUtE, grain yield/N uptake), in maize grown in environments with high and low N availability. Experiments with 31 maize genotypes (28 hybrid crosses and three controls) were carried out in soils with high and low N rates, in the southeast of the state of Minas Gerais, Brazil. There was a reduction of 23.2% in average GY for maize grown in soil with low N, in comparison to that obtained with high N. There were 26.5, 199 and 400% increases in NUtE, NUpE, and NUE, respectively, for maize grown with low N. The general combining ability (GCA) and specific combining ability (SCA) were significant for GY, NUE and NUpE for maize grown in high N soil. Only GCA was significant for NUpE for maize grown in low N soil. The GCA and SCA for NUtE were not significant in either environment. Additive and non-additive genetic effects are responsible for the genetic control of NUE and GY for maize grown in soils with high N availability, although additive effects are more important. RESUMO: O objetivo deste trabalho foi estudar o controle genético da produtividade de grãos (PG) e da eficiência no uso de nitrogênio (EUN, produção de grãos/N aplicado) e seus componentes primários - eficiência de absorção (EAbN, N absorvido/N aplicado) e utilização (EUtN, produção de grãos/N absorvido) -, em milho cultivado em ambientes com alta e baixa disponibilidade de nitrogênio. Trinta e um genótipos de milho (28 cruzamentos entre híbridos comerciais e três testemunhas) foram avaliados em solos com alta e baixa doses de aplicação de N. Houve redução de 23,2% na média de PG em milho cultivado em solo com baixo teor de N, em relação à obtida com alto N. Com baixo teor de N no solo, observaram-se aumentos de 26,5, 199 e 400% em EUtN, EAbN, e EUN, respectivamente. Em milho cultivado em solo com alto teor de N, as capacidades geral (CGC) e específica (CEC) de combinação foram significativas em PG, EUN e EAbN. Em milho de solos com baixo teor de N, apenas a CGC, na EAbN, foi significativa. A CGC e a CEC não foram significativas, em nenhum dos ambientes, na EUtN. Efeitos genéticos aditivos e não aditivos são responsáveis pelo controle genético da EUN e PG, em milho cultivado em solos com elevada disponibilidade de N, mas os efeitos aditivos são mais importantes.
