Single nucleotide polymorphisms (SNPs) are the most abundant sequence variations found in plant genomes and are widely used as molecular genetic markers in genetic diversity studies and crossbreeding programs. In this study, we examined 113 DNA sequences of the endopolygalacturonase (endo-PG) gene from 67 peach accessions and found a total of 56 SNPs and .. Read More»

Studies on intraspecific variation can contribute to the development of conservation strategies by identifying units of conservation for threatened species. Aspidosperma polyneuron is a tropical tree of seasonal semideciduous forests that is currently endangered and protected because it has been heavily logged for lumber, alth.. Read More»

Dry bean (Phaseolus vulgaris L.) is an important economic crop in Brazil but its yield can be significantly reduced by white mold, a disease caused by Sclerotinia sclerotiorum (Lib.) de Bary, a necrotrophic, highly destructive, and non-host-specific fungus. This fungus secretes numerous cell wall-degrading enzymes such as polygalacturonases, exo-β-1,.. Read More»

Retrotransposon-based molecular markers are powerful molecular tools. However, these markers are not readily available due to the difficulty in obtaining species-specific retrotransposon primers. Although recent techniques enabling the rapid isolation of retrotransposon sequences have facilitated primer development, this process nonetheless remains time-c.. Read More»

The current intense production of biological data, generated by sequencing techniques, has created an ever-growing volume of unanalyzed data. We reevaluated data produced by the guarana (Paullinia cupana) transcriptome sequencing project to identify cDNA clones with complete coding sequences (full-length clones) and complete s.. Read More»

As a model plant, mechanisms of the cytoplasmic male sterility/restoration of fertility (CMS/Rf) system in tobacco are seldom studied. Using Rf gene sequences from other Solanaceae plants and the draft genome of Nicotiana benthamiana, degenerate primers were designed to amplify the cDNA pool of N. tomentosiformis. In total, si..

Molecular genetic assessments that consider ecological information, in addition to endogamy levels, genetic diversity, and the genetic differentiation among species and populations, are particularly important for the conservation of biological diversity. Prime candidates for conservation genetic review are those subject to hum.. Read More»

Henoch-Schönlein purpura nephritis (HSPN), the most serious long-term complication of Henoch-Schönlein purpura, is one of the most common renal diseases in children. Matrix metalloproteinase-9 (MMP-9) is implicated in the pathogenesis of renal diseases. Genomic DNA was isolated from the venous blood leukocytes of 220.. Read More»

The aim of this study was to investigate the repair effect of human acellular amniotic membrane (HAAM) loading bone marrow mesenchymal stem cells (BMSCs) on articular cartilage defect in rabbits. Rabbit BMSCs were isolated and cultured, and they were then inoculated on HAAM to prepare the complex of HAAM and BMSCs. Twenty-four.. Read More»

Short rib-polydactyly syndrome type III (SRPS3) is a perinatal lethal skeletal disorder with polydactyly and multisystem organ abnormalities. While ultrasound of the fetus can detect skeletal abnormalities characteristic of SRPS3, the syndrome is often difficult to diagnose before birth. As SRPS3 is an autosomal recessive diso.. Read More»
