Similaridade genética de populações naturais de pimenta-de-macaco por análise RAPD

Abstract

Genetic similarity of natural populations of pimenta-demacaco (Piper aduncum L.) obtained throug RAPD analysisThe species known as pimenta-de-macaco (Piper aduncum L.) has great economic explotation potential based on the proved usefulness of the essential oil in agriculture and human health. The genetic diversity of their natural populations was characterized. A total of eighteen accessions of the plant, obtained from four different origins in the Brazilian Amazon, was examined by means of DNA loci, generated by RAPD analysis. Real genetic diversity was observed between the analyzed populations and it appear that the patterns of the genetic diversity follow the patterns of the geographical distribution.

The anti-inflammatory activity of dillapiole and some semisynthetic analogues

“…The Piper aduncum species occurs in several regions of the world and is also common throughout Brazil (Gaia et al, 2004). Popularly known as Matico, it produces an essential oil with great exploitative potential because it has proven effects against traditional cultures of phytopathogens, like fungi (Bastos, 1997), bacteria and mollusks (Orjala et al, 1993) as well as analgesic action with low levels of toxicity (Monteiro et al, 2001;Sousa et al, 2008).…”

Comportamento higroscópico de partes aéreas de pimenta-de-macaco (Piper aduncum L.)

“…Esta espécie é de grande importância no estudo e na exploração econômica tendo em vista a ação do óleo essencial presente nas partes aéreas desta planta sobre fitopatógenos como fungos, bactérias (Staphylococus aureus, Escherichia coli, S.pneumoniae), moluscos, ácaros e larvas, além do seu efeito analgésico e anti-inflamatório com baixos níveis de toxicidade e com a vantagem de ser um produto biodegradável (Gaia et al, 2004;Silva, 2004).…”

Restoration over time and sustainability of Schinus terebinthifolius Raddi

“…However, when working in extremely fragmented areas, or with few matrices per area, the recommendation distance is unfeasible to be used as standardization. Although some seed trees of population P present spatial distances shortest than 50 m, there is low genetic proximity (Gaia et al, 2004).…”
