Camu-camu is a shrub, native to the Amazon that thrives in areas where flooding is frequent. Genetically, the plant is characterized by a diploid genome and moderate genetic diversity. Several parts of the plant are used in traditional folk medicine to treat a variety of acute and chronic diseases. For over 50 years, the exceptionally high vitamin C content of camu-camu has attracted worldwide attention that continues today because of the recent discovery of several healthpromoting phytochemicals with corroborated biological activities (e.g., antioxidant, anti-obesity, antidiabetic). All of these beneficial attributes are well supported by in vitro and in vivo studies as well as human clinical trials. The metabolic precursors of these phytochemicals are synthesized in key metabolic pathways (i.e., the shikimate pathway, the mevalonate pathway). Of these metabolic pathways, we show details for the biosynthesis of betulinic acid, transresveratrol, and syringic acid. In conclusion, camu-camu is an exceptional plant for its ability to produce and accumulate significant amounts of a variety of health-promoting phytochemicals. Although several metabolic pathways responsible for the biosynthesis of these phytochemicals have been reconstructed based on fruit and seedling transcriptomes, detailed knowledge of the vast majority of metabolic pathways and their molecular regulatory mechanisms is lacking. Consequently, we must increase our knowledge of the metabolic processes using multi-omic approaches so that we can acquire the skills necessary to develop genetically improved varieties of camu-camu and implement biotechnological applications for the production of these bioactive phytochemicals.
Um total de 1030 flebotomíneos, pertencentes a 14 espécies, foram coletados com armadilha tipo Shannon e isca humana, nos meses de Julho e Agosto de 1991, nos horários das 18:00 h. às 21:00 h., nas localidades de San Juan, San Pedro e 25 de Diciembre localizadas na Amazônia Peruana. As fêmeas foram mais abundantes do que os machos (96,98% e 3,02% respectivamente). Os subgêneros Psychodopygus (49,27% e 7 spp. coletadas) e Nyssomyia (48,79% e 4 spp. coletadas) comportaram o maior número de espécies e indivíduos. As espécies Lutzomyia richardwardi (48,4%) e L. carrerai (29,2%) foram as mais abundantes. Na localidade de San Juan foi coletado o maior número de indivíduos (55,2%), porém o maior número de espécies foi obtido na localidade de 25 de Diciembre. Quanto a estratégia de coleta, o mesmo número de espécies (12 spp.) foram obtidos com ambas as armadilhas, porém um maior número de indivíduos foi capturado com a técnica de isca humana.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
