In vitro antifungal activity of Myrcia ovata essential oils and their major com...
White, Larissa Alves Secundo; Blank, Arie Fitzgerald; Gagliardi, Paulo Roberto; Arrigoni-Blank, Maria de Fátima; Nizio, Daniela Aparecida de CastroMyrcia ovata, an endemic species to the Brazilian Atlantic Forest, presents antifungal properties. The phytopathogens Colletotrichum acutatum, Plenodomus destruens, and Thielaviopsis paradoxa are responsible for the diseases citrus postbloom fruit drop, sweet potato foot rot, and coconut stem bleeding, respectively. The antifungal activity of the essential oils of five M. ovata chemotypes (MYRO-159, nerolic aci...
Chemical diversity of essential oils from Hyptis pectinata (L.) Poit
Feitosa-Alcantara, Rosana Barroso; Arrigoni-Blank, Maria de Fátima; Blank, Arie Fitzgerald; Nogueira, Paulo Cesar de Lima; Sampaio, Taís SantosThe essential oils are secondary metabolites formed by several chemical compounds that confer to these substances great social and economic importance. This diversity of compounds is generally determined by the genetic constitution of the plant, although environmental factors may also influence the type, amount, and concentrations of the compounds present in the essential oil. The aim of this work was to analyz...
Genetic diversity of native populations of Croton tetradenius Baill. using ISSR...
Almeida-Pereira, Camila Santos; Muniz, Ana Veruska Cruz da Silva; Alves, Rodrigo Pereira; Feitosa-Alcantara, Rosana BarrosoBrazil has about 300 Croton species in different types of vegetation. Croton tetradenius Baill., which is endemic to the Northeast region and predominant in the Caatinga vegetation, stands out among the several species of this genus. Considering the importance of knowing the genetic variability of a species, the objective of this study was to analyze the genetic diversity of the genotypes of natural populations...
Analysis of genetic diversity of Hyptis pectinata (L.) Poit. plants using ISSR ...
Feitosa-Alcantara, Rosana Barroso; Muniz, Ana Veruska Cruz da Silva; Blank, Arie Fitzgerald; Almeida-Pereira, Camila SantosHyptis pectinata, popularly known as ‘sambacaitá’ or ‘canudinho’, is a medicinal and aromatic species widely used in the Brazilian Northeast. In Sergipe, the excessive extraction of natural resources may reduce the genetic variability of native plants. Thus, molecular markers have frequently been applied to the characterization of genetic diversity as the basis for germplasm conservation and breeding programs. ...
