Genetic variability of garlic accessions as revealed by agro-morphological traits evaluated under different environments
The cultivated garlic (Allium sativum L.) displays a wide phenotypic diversity, which is derived from natural mutations and phenotypic plasticity, due to dependence on soil type, moisture, latitude, altitude and cultural practices, leading to a large number of cultivars. This study aimed to evaluate the genetic variability shown by 63 garlic accessions belonging to .. Read More»

Populations of Erythrina velutina Willd. at risk of extinction
The goal of this study was to characterize the structure of two natural populations of the coral tree using RAPD and ISSR markers. The study evaluated all individuals in two different areas in the northeastern region of Brazil: the first was in the riparian area, 10 km x 100 m along the edge of the lower São Francisco River, and the second was in the municipality of Pinhão, in a s..

Isolation and characterization of microsatellites for the yam Dioscorea cayenensis (Dioscoreaceae) and cross-amplification in D. rotundata
Dioscorea cayenensis and Dioscorea rotundata are among the most important yam species for the humid and sub-humid tropics. We isolated nine polymorphic microsatellite markers using a microsatellite-enriched genomic library technique. The nine primer pairs were validated in 22 D. cayenensis accessions, and were tested for transferability in 26 D. rotundata accessions.. Read More»

Population variability of Bemisia tabaci (Genn.) in different hosts
The silverleaf whitefly, Bemisia tabaci (Genn.) (Hemiptera: Aleyrodidae), is a cryptic species complex that contains some of the most damaging pests in tropical and subtropical regions. Recent studies have indicated that this complex is composed of at least 24 distinct and morphologically indistinguishable species that mainly differ in their ability to transmit phytoviruses, adapt to hosts, and..

Development and characterization of microsatellite loci for genetic studies of the sugarcane borer, Diatraea saccharalis (Lepidoptera: Crambidae)
We present polymorphic microsatellite markers isolated for genetic studies of the sugarcane borer, Diatraea saccharalis (Fabricius). We isolated 16 microsatellite loci through an enriched genomic library protocol. After characterization, 12 markers showed polymorphic information expressed in the observed number of alleles (ranging from 2 to 7; 5 on average) and in the polymorphism information c.. Read More»

Development and characterization of microsatellite primers in Pogostemon cablin (Lamiaceae)
Microsatellite primers were developed and optimized for patchouli (Pogostemon cablin) to characterize the patchouli Active Germplasm Bank of Universidade Federal de Sergipe. Creation of a genomic library for patchouli enabled the design of 12 microsatellite primers. Six of these microsatellites were polymorphic, revealing two well-defined groups of individuals that possess exclusive alleles. Th.. Read More»

Microsatellite markers for the Cabre?ºva 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 .. Read More»

Genetic divergence in a soybean (Glycine max) diversity panel based on agro-morphological traits
Owing to the narrow genetic basis of soybean (Glycine max), the incorporation of new sources of germplasm is indispensable when searching for alleles that contribute to a greater diversity of varieties. The alternative is plant introduction, which may increase genetic variability within breeding programs. Multivariate techniques are important tools to study genetic .. Read More»

Genetic diversity of Casearia sylvestris populations in remnants of the Atlantic Forest
Guaçatonga (Casearia sylvestris) is a native plant of the Atlantic Forest, with high medicinal potential and relevance for reforestation programs. The aim of this study was to characterize, with microsatellite markers, two populations of C. sylvestris from remaining areas of the Atlantic Forest in the State of São Paulo. High allelic variation was foun.. Read More»

New loci of Lychnophora ericoides and transferability to Lychnophora pinaster, endangered medicinal species from Brazil
Lychnophora ericoides and Lychnophora pinaster are species used in popular medicine as analgesic or anti-inflammatory 21 simple sequence repeat loci of L. ericoides were developed and transferred to L. pinaster. Three populations of L. ericoides and 2 populations of L. pinaster were evaluated; they were collected in the State of Minas Gerais. Population parameters were estimated, and the mean v.. Read More»
