Article Synopsis
  • - Campomanesia xanthocarpa is a fruit tree native to South America that has ecological and medicinal significance, but is mainly found in fragmented forest areas in southern Brazil's Atlantic Forest.
  • - This study used SSR (simple sequence repeat) markers to analyze the genetic diversity and spatial structure of C. xanthocarpa in these forest fragments, revealing moderate to high genetic diversity, with interesting patterns based on different types of genetic markers.
  • - The research indicates that for conservation efforts, it’s crucial to maintain existing forest remnants to protect unique genetic material and suggests that seed collection should focus on a larger number of individuals from each fragment to enhance genetic diversity.

The aim of this study was to develop simple sequence repeat (SSR) markers for genetic studies on , as well as to evaluate their transferability to other bamboo species. Genomic DNA was isolated from and its partial sequencing was used to find SSR loci. The obtained sequencing data were de novo assembled using the software CLC Genomics Workbench 8.

Repetitive genomic elements were prospected in , aiming to characterize these elements in a non-model plant species and to develop species-specific microsatellite markers. Approximately 4.12% of the partial genome of is composed of repetitive elements, being retrotransposons the most widely represented.

Herbicides inhibiting acetyl-coenzyme A carboxylase (ACCase) are very effective in controlling grass weeds including weedy-rice in paddy rice production systems. The ACCase inhibitor affects the enzyme by blocking fatty acid biosynthesis resulting in plant death. The herbicide resistance in rice is conferred by a single point mutation with an amino acid substitution of the carboxyl transferase domain of the ACCase gene.

Despite the high diversity of the Southern South American environments, the patterns and processes driving both their species diversity and demographic history are still poorly known and are a challenging task. In this study, we evaluate plastid DNA sequences of the conifer species Araucaria angustifolia aiming to (i) assess the species genetic structure within its main range of occurrence, (ii) infer its population demographic history, looking for evidence of southward expansion, (iii) search for evidence of glacial refugia within the species distribution area and (iv) discuss some conservation and management strategies for this species. Twenty haplotypes were identified, revealing the presence of three distinct genetic groups across the geographic range of the species and structuring the populations into Northern, Central and Southern groups.

Premise Of The Study: Microsatellite primers were identified and characterized in Acca sellowiana in order to expand the limited number of pre-existing polymorphic markers for use in population genetic studies for conservation, phylogeography, breeding, and domestication. •

Methods And Results: A total of 10 polymorphic microsatellite primers were designed from clones obtained from a simple sequence repeat (SSR)-enriched genomic library. The primers amplified di- and trinucleotide repeats with four to 27 alleles per locus.

Mycoplasma hyopneumoniae is the etiological agent of porcine enzootic pneumonia (EP), which is a respiratory disease responsible for huge economic losses in the pig industry worldwide. The commercially available vaccines provide only partial protection and are expensive. Thus, the development of alternatives for the prophylaxis of EP is critical for improving pig health.
