Comparison of eight methods to isolate genomic DNA from Hancornia speciosa

Mangabeira (Hancornia speciosa) is a native fruit tree found mainly in the Cerrado biome and shows great economic potential due to its multiple uses; the fruits are used in agriculture, are important as a food resource, and can be consumed in natura or processed. Due to a reduction in the area of ecosystems where it occurs, mangabeira is threatened by genetic erosio.. Read More»

Comparison of eight methods of genomic DNA extraction from babassu

    J.P.G. Viana, A.N.C. Borges, A.C.A. Lopes, R.L.F. Gomes, F.B. Britto, P.S.C. Lima and S.E.S. Valente

Babassu (Orbignya phalerata Martius) is one of the most important palms in Brazil because of the largest morphological variation, wide geographic distribution, and high socio-economic importance. The diversity present in babassu germplasm should be protected against loss to ensure their use with high productivity. Study of the available variability in populations of babassu is necessary to deve.. Read More»

DNase concentration assay to obtain DNA-free RNA from sugarcane leaves

    J.A. Santos, G.A. Luz, K.P. Oliveira, L.F. Oliveira, A.S. Andrade Júnior, S.E.S. Valente and P.S.C. Lima

The success of gene expression studies, protein synthesis, and construction of cDNA libraries directly depends on the purity and integrity of the RNA used in these tests, as even minor amounts of contaminant DNA (<1%) can produce a false positive amplification signal in quantitative real-time PCR. For RNA contaminated with genomic DNA, an essential step in the st.. Read More»

Genetic variation detected by RAPD markers in natural populations of babassu palm (Attalea speciosa Mart.)

    M.F. Santos, K.J. Damasceno-Silva, M.A. Carvalhaes and P.S.C. Lima

The purpose of this study was to analyze the effects of management on the genetic structure of natural populations of Attalea speciosa in the State of Piauí, Brazil, using randomamplified polymorphic DNA (RAPD) markers. Three babassu populations under different management systems were selected. Polymerase chain reactions were performed for 20 RAPD primers. A total of 146 bands were gener.. Read More»

Investigating genetic diversity in sapucaia using inter simple sequence repeat markers

    R.C. Borges, F.M.G. Santos, M.C.C. Maia, P.S.C. Lima and S.E.S. Valente

Sapucaia is a tree species originating from the Brazilian Amazon and is widely distributed in Brazil, especially in the mid-north region (Piauí and Maranhão states). Its seeds are rich in calories and proteins, and possess great potential for commercialization. Little is known about the genetic variability in the germplasm of most Lecythis species. Here, 11 inter-simple sequence r.. Read More»

RAPD analysis of the genetic diversity among accessions of Fabaceous forages (Poincianella spp) from the Caatinga

    R.F.M. Mendes, R.B. Araujo Neto, M.P.S.B.C. Nascimento and P.S.C. Lima

Among members of the Fabaceae family, native to the Brazilian Caatinga, the species Poincianella pyramidalis and P. bracteosa exhibit particular potential as forage for cattle, sheep and goats. With the aim of establishing genetic relationships within Poincianella, random amplified polymorphic DNA analysis was performed on eight accessions of P.. Read More»

Evaluation of genetic similarity between accessions of Pityrocarpa moniliformis (angico-de-bezerro) using RAPD markers

    F.M.S. Sousa, R.M. Mendes, R.F.M. Mendes, R.B. Araujo Neto, M.P.S.B.C. Nascimento and P.S.C. Lima

Pityrocarpa moniliformis (Benth.) Luckow and Jobson, commonly known as angico-de-bezerro, is a forage legume that occurs naturally in the Caatinga of northeastern Brazil. This fast growing, vigorous, melliferous tree is well adapted to arid terrains and its branches and leaves possess high nutritional value. However, the scarcity of information regarding genetic variability within the .. Read More»

RAPD analysis of the genetic diversity of mango (Mangifera indica) germplasm in Brazil

    I.G.B. Souza, S.E.S. Valente, F.B. Britto, V.A.B. de Souza and P.S.C. Lima

We evaluated genetic variability of mango (Mangifera indica) accessions maintained in the Active Germplasm Bank of Embrapa Meio-Norte in Teresina, Piauí, Brazil, using RAPDs. Among these accessions, 35 originated from plantings in Brazil, six from the USA and one from India. Genomic DNA, extracted from leaf material using a commercial purification kit, was su..

Molecular characterization of caj�¡, Spondias mombin (Anacardiaceae), by RAPD markers

    A.T.B. Lima, V.A.B. de Souza, R.L.F. Gomes and P.S.C. Lima

The arboreal species Spondias mombin L. (Anacardiaceae) is widely distributed in Brazil, where the fruits, known by the common name of cajá, are an important commercial commodity. We evaluated genetic variability among 32 cajá accessions of the Germplasm Collection of Embrapa Meio-Norte using RAPD technique. Reaction conditions for efficient RAPD ampli.. Read More»
