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..

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 diversity of Lippia sidoides Cham. and L. gracilis Schauer germplasm
The conservation of plants in germplasm banks ensures the characterization and availability of these resources for future generations. The present study used DNA markers to obtain genetic information about germplasm collections of Lippia sidoides and L. gracilis, which are maintained in an Active Germplasm Bank (AGB). Genetic variability of samples in the AGB was assessed using 12 combinations .. Read More»

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»

Cross-species amplification and polymorphism of microsatellite loci in Helicoverpa armigera and Helicoverpa zea (Lepidoptera: Noctuidae) in Brazilian cropping systems
The Old World bollworm Helicoverpa armigera (Hübner) was recently discovered in Brazil. This species is closely related to the New World bollworm H. zea (Boddie), and mating between these species has already been reported under laboratory conditions. Here, we tested the cross-species amplification of 20 microsatellite (SSR) loci in field populations of H. armig.. 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»

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»

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..
