Mineral elements in barley (Hordeum vulgare) play an important physiological role in global human health. In this study, quantitative trait loci (QTLs) for concentration of nine mineral elements in barley grain and grass powder were detected in a population of 193 recombinant inbred lines of the barley cross Ziguangmangluoerling x Schooner and the parents. We observed large genetic variation ... more

Cynodon is a genus of plants with forage potential that has attracted the interest of breeders. These species have high morphological variability in a large number of varieties and cytotypes, hampering identification. This study aimed to determine the karyotype asymmetry index among accessions of Cynodon to discriminate between them. Karyotype symmetry was based on three estimates, which were ... more

Quantitative fluorescent polymerase chain reaction (QF-PCR), in recent years, has been accepted as a rapid, high throughput, and sensitive method for prenatal diagnosis of common chromosomal aneuploidies. Since short tandem repeats (STRs) are the cornerstone of QF-PCR technique, selection of the most polymorphic STR markers is an essential step for a successful QF-PCR assay. The genetic ... more

Measures to control maize white spot (MWS) caused by Pantoea ananatis are preferentially based on resistant cultivars. A lack of knowledge on the genetic variability of pathogens could interfere with the development and utilization of controlling strategies in this pathosystem. The main goals of this study were to investigate the genetic variability of 90 P. ananatis isolates from three ... more

Annona; Bayes Theorem; Brazil; cluster analysis; Genetic variation; Genetics, Population; Genotype; Microsatellite Repeats

Habitat fragmentation has numerous consequences, particularly to endemic species, and has a negative impact on the genetic diversity of neglected species, leading to genetic drift. Annona crassiflora Mart. is a species that is endemic to Brazil, and its incidence in the Cerrado biome has decreased. The identification and characterization of its remaining diversity is necessary for its ... more

Because of their local adaptation and economic factors that limit the adoption of commercial hybrids, farmer-saved maize landraces are still grown over a considerable area concentrated in southwest China. To evaluate the potential of using maize landraces, the germplasm characteristics of 96 landraces from southwest China were evaluated at phenotypic, cellular, and molecular levels. The ... more

Cajazeira (Spondias mombin L.), of the family Anacardiaceae, is a species of fruit tree found in the Amazon region with fruits that have excellent prospects for commercial use. We aimed to evaluate the genetic diversity within and among natural populations of S. mombin, with natural occurrence in northern Mato Grosso State, by using inter-simple sequence repeat (ISSR) markers. Overall, 126 ... more

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 found in both populations (N = 101 and 117; A ... more

Inter-simple sequence repeats (ISSRs) were used to analyze the genetic diversity of 21 accessions obtained from four provinces in China, Shandong, Henan, Hebei, and Sichuan. A total of 272 scored bands were generated using the eight primers previously screened across 21 accessions, of which 267 were polymorphic (98.16%). Genetic similarity coefficients varied from 0.4816 to 0.9118, with an ... more

Casearia grandiflora (Salicaceae) is a typical Cerrado species adapted to disturbed environments, making it useful for restoration projects. Knowledge of genetic diversity is important for establishing conservation strategies for this species. This study aimed to compare chloroplast haplotype diversity and structure of C. grandiflora, under the assumption that protected areas hold greater ... more
