Recently, the genotype plus genotype x environment interaction (GGE) biplot methodology has been used to investigate genotype x environment interactions in several crop species, but has not been applied to the common bean (Phaseolus vulgaris L.) crop in Brazil. The aim of this study was to identify common bean genotypes that exhibit high grain yield and s.. Read More»

Five published DNA extraction protocols were compared for their ability to produce good quality DNA from fresh and herbarium leaves of several species of the genus Dalbergia. The leaves of these species contain high amounts of secondary metabolites, which make it difficult to perform a clean DNA extraction and thereby interfer.. Read More»

Cambui (Myrciaria tenella O. Berg) is a native species from Brazil, which belongs to the family Myrtaceae. Molecular characterization is one of the most used tools for the study of the biotechnological potential of species because the diversity level between individuals can be inferred. Analysis of genetic diversity is fundame.. Read More»

The population of Pará (a state in Brazil) has a very characteristic food culture, as a majority of the carbohydrates consumed are obtained from cassava (Manihot esculenta Crantz) derivatives. Tucupi is the boiled juice of cassava roots that plays a major role in the culinary footprint of Pará. Before boiling, th.. Read More»

The efficacy of genetic material for use as DNA barcodes is under constant evaluation and improvement as new barcodes offering better resolution and efficiency of amplification for specific species groups are identified. In this study, the chloroplast intergenic spacer psbK-psbI was evaluated for the first time as a DNA barcode for distinguishing date pal.. Read More»

The lethal gene ‘Luteus-Pa’ is found in cacao genotypes (Theobroma cacao) of the Parinari (Pa) series, from Peru. Seedlings affected by this gene have yellowing leaves and subsequently die. We mapped this gene based on microsatellite markers and RAPDs, in order to elucidate the inheritance of ‘Luteus-Pa&rsquo.. Read More»

This study was performed to identify and analyze the phylogenetic relationship among four herbaceous species of the genus Paeonia, P. lactiflora, P. japonica, P. veitchii, and P. suffruticosa, using DNA barcodes. These four species, which are commonly used in traditional medicine as Paeoniae Radix and Moutan Radicis Cortex, are pharmaceutically defined in.. Read More»

This study aimed to evaluate the clustering pattern consistency of soybean (Glycine max) lines, using seven different clustering methods. Our aim was to evaluate the best method for the identification of promising genotypes to obtain segregating populations. We used 51 generations F5 and F6 soybean lines originating from diffe..

Anopheles (Nyssorhynchus) oswaldoi (Peryassú, 1922) s. l., which has been incriminated as a potential human malaria vector in Western Brazilian Amazon, may constitute a cryptic species complex. However, the most recent study with isozymes indicated high similarity among samples from the States of Acre, Amazonas and Rond.. Read More»

Cassava is the main staple for more than 800 million people in the tropics. It is propagated vegetatively by stem cuttings, which maintains superior genotypes but favors disease accumulation and spread. In this report, we present the results of the screening of the progeny and the second generation of the clone UnB 307 for apo.. Read More»
