The genetic diversity of the genus Crotalaria is unknown even though many species in this genus are economically valuable. We report the first study in which polymorphic expressed sequence tag-simple sequence repeat (EST-SSR) markers derived from Medicago and soybean were used to assess the genetic diversity of the Crotalaria germplasm collection. This collection consisted of 26 accessions repr...

Crotalaria (Fabaceae) is the largest legume genus represented by 81 species in India. The existing sectional classification for Crotalaria in India is based on morphological characters and is not completely supported by the molecular phylogenetic studies. Molecular systematic studies of the Indian sections Crotalaria and Calycinae have enabled merging of both these sections into Calycinae. Trif...

The host suitability of five of the most common weed species occurring in maize (Zea mays L.) fields in South Africa to Pratylenchus zeae was tested. Based on the number of nematodes per root unit, mealie crotalaria (Crotalaria sphaerocarpa) was a good host; goose grass (Eleusine indica), common pigweed (Amaranthus hybridus), and thorn apple (Datura stramonium) were moderate hosts; and khaki we...

The effects of intercycle cover crops on Rotylenchulus reniformis population densities in pineapple were evaluated in one greenhouse and two field experiments. In the greenhouse, Crotalaria juncea, Brassica napus, and Tagetes erecta were planted for 3 months and then incorporated. These treatments were compared to weedy fallow with or without 1,3-dichloropropene (1,3-D) in three soils (Makawao ...

ETHNOPHARMACOLOGICAL RELEVANCE Crotalaria species have been widely used in Chinese traditional medicine to treat several types of internal cancers. Crotalaria agatiflora is used as a medicinal plant in several African countries for the treatment of bacterial and viral infections as well as for cancer. MATERIALS AND METHODS Water and ethanol extracts of the leaves of Crotalaria agatiflora were...

Crotalaria juncea (Leguminoceae) has been used for its antiarthritic effect in the folklore medicine. The purpose of this study was investigating experimentally the possible antiarthritic and antiulcerogenic properties of Crotalaria juncea leaves in animal model. Ethanolic extract of Crotalaria juncea (CJE) was administered at the doses of 200 and 400 mg/kg to complete Freund’s adjuvant (...

Phytochemical investigation of the whole plants of Crotalaria sessiliflora L. led to the isolation of four flavonoids. The structures of these compounds were identified as 2',4',5,7-tetrahydroxyisoflavone (1), 2',4',7-trihydroxyisoflavone (2), 4',7-dihydroxyflavone (3), and isovitexin (4) using spectroscopic analysis. Among these, compounds 2, and 3 have not been reported from Crotalaria specie...

Millet, milo, soybean, crotalaria, and Norman pigeon pea were used in conjunction with clean fallow and a nematicide (fensulfothion) for managing nematode populations in the production of tomato transplants (Lycopersicon esculentum Mill.). Glean fallow was the most effective treatment in suppressing nematode numbers. After 2 years in tomato, root-knot nematodes increased in numbers to damaging ...

The metabolic interactions and signaling between neurons and glial cells are necessary for the development and maintenance of brain functions and structures and for neuroprotection, which includes protection from chemical attack. Astrocytes are essential for cerebral detoxification and present an efficient and specific cytochrome P450 enzymatic system. Whilst Crotalaria (Fabaceae, Leguminosae) ...

Laboratory and greenhouse experiments were carried out to study food and oviposition preference by Phyllophaga cuyabana (Moser) on different plant species as Cajanus cajan L. (pigeon pea), Crotalaria juncea L. (sun hemp), Crotalaria spectabilis Roth (showy crotalaria), Crotalaria ochroleuca G. Don (slenderleaf rattlebox), Glycine max [L.] Merrill (soybean), Gossypium hirsutum L. (cotton), Helia...
