“…Na literatura atual é possível encontrar alguns trabalhos que demonstram a potencialidade de extratos de plantas do gênero Capsicum (GUIMARÃES, et al, 2013;CORRÊA, 2015;VIEIRA JUNIOR et al, 2016). CORRÊA (2015) testando extratos dos frutos e folhas de Capsicum frutescens e C. baccatum sobre o fungo C. gloeosporioides demonstrou que os mesmos apresentaram propriedades fungitóxicas inibindo o crescimento micelial em 32,16 e 27,37% comparados com o controle.…”

RESUMONos últimos 30 anos tem-se observado, por parte da sociedade, uma maior preocupação com o uso de agrotóxicos na agricultura. Nesse sentido, a pesquisa tem buscado incansavelmente produtos alternativos, que sejam mais eficientes, baratos e ambientalmente seguros. Dentre as alternativas buscadas, o uso de extratos de plantas tem se mostrado promissor. Nesse sentido, o presente trabalho teve como objetivo testar 48 extratos aquosos e alcoólicos de 18 variedades de pimentas do gênero Capsicum obtidos a partir de sementes, folhas e frutos pelo método de maceração para o controle na inibição de germinação de Hemileia vastatrix e crescimento micelial dos fungos Colletotrichum lindemuthianum, Alternaria sp., Fusarium sp. Colletotrichum gloeosporioides e Phomopsis. Destes, o extrato aquoso, obtido de sementes de Capsicum chinense foi o mais eficiente, controlando todos os fitopatógenos desafiantes, mostrando que esses extratos possuem compostos bioativos possíveis de controlar fungos fitopatogênicos. PALAVRAS-CHAVE: Doenças fúngicas, Inibição, Método alternativo. EXTRACTS OF CAPSICUM SPECIES IN THE IN VITRO CONTROL OF AGRICULTURAL IMPORTANCE PATHOGENSABSTRACT Over the last 30 years, there has been a growing concern about the use of agrochemicals in agriculture. In this sense, the researchers has been relentlessly pursuing alternative products that are more efficient, cheap and environmentally safe. Among the alternatives sought, the use of plant extracts has shown promise. In this sense, the present work had the objective of testing 48 aqueous and alcoholic extracts of 18 varieties of Capsicum peppers obtained from seeds, leaves and fruits by the maceration method to control the inhibition of Hemileia vastatrix germination and mycelial growth of Fungi Colletotrichum lindemuthianum, Alternaria solani, Fusarium solani, Colletotrichum gloeosporioides and Phomopsis sp. From these, the aqueous extract obtained from Capsicum chinense seeds was the most efficient, controlling all the challenging phytopathogens

“…In view of the great diversity of species belonging to Solanaceae that are present in the Brazilian flora, it is known that many of these have economic importance used as food, pharmacological substances production, and ornamentation. Additionally, plants belonging to this family are also sources of bioactive secondary metabolites of different chemical classes, such as steroidal alkaloids, tropane alkaloids, pyridine alkaloids, vitanolides, glycoalkaloids, flavonoids, among others, which have the most diverse applications (Corrêa, 2015).…”

The Solanaceae family comprises about 100 genera and 2,500 species, with a cosmopolitan distribution and greatest diversity in the Neotropical region. In Brazil, 36 genera and 506 species have been identified, including 236 endemic species. The family has a high diversity of species of economic importance as a source of food, medicinal extracts, and for ornamental use. The species are sources of bioactive secondary metabolites, with diverse applications. We made ae structural and functional characterization and developed three-dimensional models of putrescine Nmethyltransferase (PMT) proteins, a key enzyme of secondary metabolism, involved in biosynthesis of nicotine, tropane alkaloids, and calistegines. We examined 48 PMT sequences from Solanaceae species available in public databases. A hydrophilic characteristic of PMT was found for all species, and the isoelectric point demonstrated a somewhat acidic character (5.4 -6.6). We identified four functional domains in the PMT sequences. Cluster analysis by Neighbor-Joining was consistent with recent taxonomic classifications of the species.
