Better knowledge of medicinal plant species and their conservation is an urgent need worldwide. Decision making for conservation strategies can be based on the knowledge of the variability and population genetic structure of the species and on the events that may influence these genetic parameters. Achyrocline flaccida (Weinm.) DC. is a native plant from the grassy fields of South America with ...

Although tomato psyllid, Bactericera cockerelli (Sulc) (Homoptera, Psyllidae), annually causes significant losses in potato and tomato crops in eastern Mexico and the central United States, infestations in western North America have been historically rare. However, substantial populations appeared in 2001 in western North America and caused losses in tomato production exceeding 80%; losses in 2...

The nutritive value of alsike clover (Trifolium hybridum L.) is slightly lower than that of red and white clovers; however, it exhibits some advantages – persists longer in a sward, performs well on acid and wet soils, suits for forage and silage production, can be used as green manure, and is a melliferous plant. With declining liming volumes, the soils are rapidly acidifying, which may result...

molecular characterization of 19 jatropha accessions that included 15 accessions of j.curcas and 4 different species was carried out using 3 different markers systems. highest polymorphism (96.67%) was recorded by rapd followed by damd (91.02%) and issr (90%). polymorphism information content (pic) was higher for damd (0.873) and almost equal for rapd (0.863) and issr (0.862) markers, whereas r...

Abstract Background Euphorbia is the largest genus in family Euphorbiaceae with a great biological and genetic diversity. The anti-trypanosomal activity of crude extract 15 species against Trypanosoma brucei was carried out. Furthermore, DNA fingerprinting tested using ISSR SCoT markers also investigated. Results revealed highest E. officinarum L. milli Des Moul. IC 50 values < 10 ?g/mL afte...
