Microsatellite Markers For The Cabreúva Tree, Myroxylon Peruiferum (fabaceae), An Endangered Medicinal Species From The Brazilian Atlantic Forest

The Cabreúva tree, Myroxylon peruiferum, is an endangered tropical species from Brazil used in forest restoration projects. It is known for its medicinal properties. Eleven microsatellite markers were developed for this species, from a microsatellite-enriched library. Nine of these markers, characterized in 30 individuals from a semideciduous forest remnant population in southeast Brazil, were polymorphic, with allele numbers ranging from 2 to 8 per locus; expected and observed heterozygosities ranged from 0.103 to 0.757 and 0.107 to 0.704, respectively. One locus (Mpe-C04) showed significant deviation from Hardy-Weinberg equilibrium, probably due to null alleles. Two other loci (Mpe-E09 and Mpe-H07) were monomorphic in this population. These microsatellite loci should be useful for future population genetic studies of this species.13369206925Billotte, N., Lagoda, P.J.L., Risterucci, A.M., Baurens, F.C., Microsatellite-enriched libraries: Applied methodology for the development of SSR markers in tropical crops (1999) Fruits, 54, pp. 277-288Calmon, M., Brancalion, P.H.S., Paese, A., Aronson, J., Emerging threats and opportunities for large-scale ecological restoration in the Atlantic Forest of Brazil (2011) Restoration Ecol., 19, pp. 154-158Carvalho, T.A., Lattanzio, N.A., Lucarini, R., Fernandes, J.B., Potencial Bactericida de Extratos e Substâncias Isoladas de Myroxylon Peruiferum (Cabreúva) Frente à Micobactérias do Trato Respiratóio (2008) XVI Congresso de Iniciação Científica., , UFSCar, SorocabaDoyle, J.J., Doyle, J.L., Isolation of plant DNA from fresh tissue (1990) Focus, 12, pp. 13-15Gonçalves, A.L., Alves Filho, A., Menezes, H., Estudo comparativo da atividade antimicrobiana de extratos de algumas árvores nativas (2005) Arq.

Híbridos interespecíficos de palmiteiro (Euterpe oleracea x Euterpe edulis) Interespecific hybrids of heart of palm plants (Euterpe oleracea x Euterpe edulis)

Compararam-se o desenvolvimento vegetativo e a produção de híbridos de palmiteiro (Euterpe oleracea x E. edulis) com seus genitores, em duas condições diferentes de cultivo, na região de Ubatuba, SP. Em ambas as situações, os híbridos apresentaram vigor e precocidade aliados à capacidade de regeneração, mostrando-se superiores à população parental em crescimento vegetativo e produção de palmito. Embora o material ainda não seja homogêneo, os híbridos interespecíficos revelaram grande potencialidade para serem usados no cultivo racional do palmiteiro.<br>The vegetative growth and yield of the Euterpe oleracea x E. edulis hybrid palms were compared to the parental population under two different shading conditions. In both conditions hybrid palms were superior to the parents in growth and yield. The hybrids were vigorous, precocious and had tillering capacity. In spite of the hybrid heterogeneity, they appeared to offer a great potential for upgrading heart of palm planting material in São Paulo State, Brazil
