Croton antisyphiliticus Mart. is a medicinal plant native to Cerrado vegetation in Brazil, and it is popularly used to treat urogenital tract infections. The objective of the present study was to assess the genetic variability of natural C. antisyphiliticus populations using AFLP molecular markers. Accessions were collected in the states of Minas Gerais, São Paulo, and Goiás. The genotyping of individuals was performed using a LI-COR® DNA Analyzer 4300. The variability within populations was found to be greater than the variability between them.
Cotton has been collected in Brazil for decades for its conservation, evaluation, and the use of its genetic resources. Gossypium mustelinum is an allotetraploid cotton species that only occurs in Brazil, and little is known about its genetic potential for improvement. However, the species is threatened by habitat fragmentation and interspecific hybridization with exotic species of cotton. In this study, we investigated the rate of natural hybridization in two populations of G. mustelinum in Bahia, Brazil, with G. hirsutum and G.
We isolated and characterized microsatellite loci for the red-crowned crane (Grus japonensis) from a microsatellite-enriched database, which was obtained using high-throughput sequencing technology. We designed primer sets for 445 microsatellite loci and after initial screening, 34 loci were genotyped in 31 red-crowned cranes. The number of observed alleles ranged from 3 to 10. Observed and expected heterozygosities ranged from 0.197 to 0.935 and 0.453 to 0.887, respectively; the mean polymorphic information content was 0.663.
Pteroceltis tatarinowii (Ulmaceae) is a scientifically and economically important temperate deciduous tree that is endemic to China. In the present study, 12 P. tatarinowii polymorphic microsatellite loci were developed using the tailed primer-M13-simple sequence repeats (TP-M13-SSR) biotin-capture method. The number of alleles per locus ranged from 2 to 10, with an average of 6.58. The observed and expected heterozygosity ranged from 0.208 to 0.958 and from 0.198 to 0.858, with average values of 0.703 and 0.710, respectively.
Maytenus truncata (Celastraceae) is a plant species widely used in the treatment of ulcers and tumors. Despite the intensive harvest of native specimens in the State of Bahia, northeastern Brazil, there is no information about the genetic variability or structure of this species. Therefore, the goal of this study was to estimate the genetic diversity and population structure of M. truncata based on inter simple sequence repeat (ISSR) molecular markers.
