Plant-parasitic nematodes, particularly root-knot nematodes (RKN: Meloidogyne spp.) and cyst nematodes (CN: Globodera and Heterodera spp.) cause severe yield reduction in most cultivated crops and are of high economic importance. African nightshade (Solanum spp.) and

A cultivation-independent approach was used to identify potentially nitrogen-fixing endophytes in seven sweet potato varieties collected in Uganda and Kenya. Nitrogenase reductase genes (nifH) were amplified by PCR, and amplicons were cloned in Escherichia coli. Clones were grouped by restriction

African potato (AP) is widely used as an immune booster for the treatment of various ailments. The norlignan glycoside hypoxoside, a major phytoconstituent of AP, its aglycon rooperol, and an aqueous preparation of lyophilized AP corms were screened for in vitro antioxidant activity using the DPPH

The effects of aqueous and methanolic extracts of Hypoxis hemerocallidea corm, locally known as 'African potato' in South Africa, were examined on rat paw edema induced by subplantar injections of fresh egg albumin (0.5 ml/kg). Acetyl salicylic acid (100 mg/kg p.o.) was used as the reference

Diabetes mellitus has been recognized as a clinical syndrome since ancient times, and remains a crippling global health problem today. It is a group of heterogeneous, autoimmune, hormonal and metabolic disorders, often accompanied by hypertension, hyperlipidemia and obesity. Current estimates

This study was undertaken to investigate the bronchorelaxant effect of Hypoxis hemerocallidea corm ('African potato') aqueous extract (APE) on spasmogen-provoked contractions of guinea-pig isolated tracheal smooth muscle preparations. APE (25-400 mg/ml) relaxed spasmogen (histamine-, carbachol- and

This study examined commonly consumed high-fat food sources to estimate dietary fat intake among 314 urban, African American adolescents (mean age (SD)=12.57 (.98) years; 66% female; 91% African American non-Hispanic; and 9% African American Hispanic). Youths' fat intake was measured using the Block

Severe late blight epidemics in South Africa in 1995 and 1996 prompted an investigation into the mating type, genotype, and metalaxyl sensitivity of populations of Phytophthora infestans. A country-wide survey was conducted from 1996 to 1998 in which isolates were collected from 101 potato fields

Full-fat African breadfruit flour was used to replace 30, 40, 50, 60 and 70% of sweet potato flour. The chemical composition and functional properties of composite flours showed that they contain more protein, fat, and ash and less carbohydrate than sweet potato flour. With increasing level of

Extracts of Hypoxis hemerocallidea corm (African potato) are commonly used by some traditional health practitioners in KwaZulu-Natal Province of South Africa as natural antenatal remedy to prevent threatening or premature abortion and miscarriage, and to ensure successful confinement. In this study,

Background: African Potato (hypoxis hemerocallidea), is used for enhancing immune system in Southern Africa. It is among the plants of intense commercial and scientific interest; hence, the aim of this study was to describe its chemistry

The coat protein (CP) gene of 75 South African Potato virus Y (PVY) isolates was amplified using reverse-transcriptase polymerase chain reaction (RT-PCR). The resulting cDNA products were cloned and sequenced. These sequences were used to identify the strains to which the isolates belonged. Some,

Brachyspira hyodysenteriae is the causative agent of swine dysentery and induces a characteristic mucosal inflammation resulting in pronounced typhlocolitis in swine and mice. Hypoxis hemerocallidea corm (African potato) is a traditional medicine in southern Africa. An African potato methanolic
