Groundnut (Arachis hypogaea) plants with rosette disease contain a manually transmissible virus, groundnut rosette virus (GRV), which depends on a luteovirus, groundnut rosette assistor virus (GRAV), for transmission by the aphid Aphis craccivora. No virus-like particles have been reported for GRV but infected plants yield infective ssRNA. Infected leaves also contain dsRNA with prominent elect...

Bambara groundnut (Vigna subterranea (L.) Verdc.) is an African legume and is a promising underutilized crop with good seed nutritional values. Low temperature stress in a number of African countries at night, such as Botswana, can effect the growth and development of bambara groundnut, leading to losses in potential crop yield. Therefore, in this study we developed a computational pipeline to ...

To evaluate the hepatoprotective and in vivo antioxidant effect of aqueous seed extract of Vigna unguiculata (AVU) against Carbon tetrachloride (CCl4) induced hepatic injury in rats. 30 male wistar rats were divided into five groups. Group 1 and 2 received plain groundnut oil (3ml/kg body weight p.o.) for 21 days and had free access to food and water. Group 3, 4 and 5 were pretreated with Silym...

In a recent paper (Basil, Sen and Sen Gupta, 1945) we have shown that groundnut meal affords a culture medium for the growth of various intestinal organisms when it is digested with some proteolytic enzyme. The hydrolysate when further admixed with a trace of liver extract gives still better results. The latter observation led us to work on the growth of other delicate organisms, and the experi...

AIMS The aims of the study were to quantify aflatoxins, the potent carcinogens associated with stunting and immune suppression, in maize and groundnut across Zambia's three agroecologies and to determine the vulnerability to aflatoxin increases after purchase. METHODS AND RESULTS Aflatoxin concentrations were determined for 334 maize and groundnut samples from 27 districts using lateral-flow ...

Groundnut is an economically important N​2-fixing legume that can contribute about 100-190kgNha-1 to cropping systems. In this study, groundnut-nodulating native rhizobia in South African soils were isolated from root nodules. Genetic analysis of isolates was done using restriction fragment length polymorphism (RFLP)-PCR of the intergenic spacer (IGS) region of 16S-23S rDNA. A total of 26 IGS t...

AIM To isolate and characterize groundnut-associated bacterial isolates for growth promotion of groundnut in field. METHODS AND RESULTS Three hundred and ninety-three groundnut-associated bacteria, representing the geocarposphere, phylloplane and rhizosphere, and endophytes were applied as seed treatment in greenhouse. Maximum increase in plant biomass (up to 26%) was observed following treat...

Cultivated groundnut (Arachis hypogaea L.), is an important oil seed crop grown mostly in tropical and subtropical regions of the world. However, it suffers with narrow genetic diversity due to genetic bottlenecks such as the recent polyploidization and self pollinating nature of the crop. In such crop species, simple sequence repeats (SSRs), as compared to other marker systems such as restrict...

Fermentation is one of the industrially important processes for the development of microbial metabolites that has immense applications in various fields. This has prompted to employ fermentation as a major technique in the production of phytase from microbial source. In this study, a comparison was made between submerged (SmF) and solid-state fermentations (SSF) for the production of phytase fr...
