Isolation and characterization of microsatellite markers for Canavalia cathartica and C. lineata (Fabaceae)1

UNLABELLED PREMISE OF THE STUDY Microsatellite markers were developed for the sea-dispersed legume Canavalia cathartica to investigate its genetic diversity and population structure. We also applied these microsatellite markers to the closely related species C. lineata. • METHODS AND RESULTS Ten primer sets were developed for C. cathartica, and all of the primers were amplified in C. linea...

Molecular cytogenetic characterization and comparison of the two cultivated Canavalia species (Fabaceae)

The two cultivated Canavalia (Adanson, 1763) species, Canavalia gladiata (N. J. von Jacquin, 1788) A. P. de Candolle, 1825 and Canavalia ensiformis (Linnaeus, 1753) A. P. de Candolle, 1825 are closely related based on morphological and molecular phylogenetic data. However, the similarities and differences in genome organization between them have not been evaluated at molecular cytogenetic level...

Piper aduncum against Haemonchus contortus isolates: cross resistance and the research of natural bioactive compounds Piper aduncum contra isolados de Haemonchus contortus: resistência cruzada e a pesquisa de bioativos naturais

The anthelminthic activity of the essential oil (EO) of Piper aduncum L. was tested in vitro on eggs and larvae of resistant (Embrapa2010) and susceptible (McMaster) isolates of Haemonchus contortus. The EO was obtained by steam distillation and its components identified by chromatography. EO concentrations of 12.5 to 0.02 mg/mL were used in the egg hatch test (EHT) and concentrations of 3.12 t...
