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: This study evaluated the efficiency of two d-cloprostenol injections at different intervals on the reproductive parameters of dairy goats. Trial 1 comprised 54 goats allocated to receive two 37.5?g d-cloprostenol doses at intervals of seven (T7, n=19), 10 (T10, n=18), and 11.5 (T11.5, n=17) days. Trial 2 comprised 62 goats allocated to receive injections at T7 (n=30) and T11.5 (n=32). Ultrasonography was done and blood was collected just before d-cloprostenol injections. After the second dose, goats were artificially inseminated (AI) with frozen-thawed semen at 18-24h (Trial 1) or at 10-24h (adjusted according to the time of estrus onset in Trial 2) after estrus detection. Estrus response rate did not differ (P>0.05) among groups in Trials 1 (T7=94.7%; T10=88.9%; T11.5=88.2%) and 2 (T7=90.0%; T11.5=96.9). All females showed progesterone concentrations >1ng/mL before both d-cloprostenol injections. The largest follicle diameter present on ovaries was similar (P>0.05) among treatments at the first and second dose. The second largest follicle diameter was superior (P<0.05) to T7 than to T10 and T11.5 goats at first dose only. This possibly resulted in lower interval to estrus (P<0.05) in T7-treated goats than other treated goats in both trials. The conception rate was similar among treatment groups in Trials 1 (T7=55.6%; T10=18.8%; T11.5=26.7%) and 2 (T7=85.2%; T11.5=93.6%). The three treatments efficiently synchronized estrus. T7 and T11.5 protocols resulted in high estrus synchrony and conception rates when adjusting the AI time according to interval of estrus.
