In a study of residues from gourd and squash artifacts, we recovered starch grains from manioc (Manihot esculenta), potato (Solanum sp.), chili pepper (Capsicum spp.), arrowroot (Maranta arundinacea), and algarrobo (Prosopis sp.) from feasting contexts at the Buena Vista site, a central Peruvian preceramic site dating to approximately 2200 calendar years B.C. This study has implications for the...

A molecular, anatomical and cytogenetic study of an interspecific hybrid between Manihot esculenta (cassava) and the wild species M. oligantha was carried out. Cytogenetics revealed relatively complete chromosome pairing and high viability of the pollen grains. Ovule structure examined by the clearing method showed polyembryony in 2.7% of the ovules. Doubling of the chromosome number resulted i...

Accelerated breeding of plant species has the potential to help challenge environmental and biochemical cues to support global crop security. We demonstrate the over-expression of ArabidopsisFLOWERING LOCUS T in Agrobacterium-mediated transformed cassava (Manihot esculenta Crantz; cultivar 60444) to trigger early flowering in glasshouse-grown plants. An event seldom seen in a glasshouse environ...

Cassava mosaic disease (CMD) is the most widespread and economically important disease of cassava (Manihot esculenta Crantz) in tropical Africa. A disease of cassava was first described in East Africa in the nineteenth century (Warburg, 1894) and cassava mosaic, as it came to be called, was subsequently reported as spreading throughout the cassava-growing areas of Central and West Africa (Calve...

The effect of 3 organic soil amendments viz., cassava peel (Manihot esculenta, Cranz), sawdust (Gmelina arborea, Roxb) and leaves (Cedrela odorata, L) on the stalk rot maize (Zea mays L.) caused by Fusarium verticillioides was investigated. Fourteen treatments made up single or combined with pathogenic non-pathogenic inoculation concentrations 3:1, 2:2 1:3 were added to 15.8 g sterilized soil. ...

The volume of secretion obtained from adult Zonocerus variegatus (Orthoptera: Pyrgomorphidae) was influenced by the type of food plants. Insects fed on leaves of cassava Manihot esculenta, bitter leaves Vernonia amygdalina, and a mixture of M. esculenta and Acalypha wilkesiana gave a good volume of secretion while Chromolaena odorata, Elaeis guinensis, Aspilia africana and Citrus sinensis did n...

Plant remedies, despite their innocuity reputation, are implicated in adverse events. The present review focuses on 30 popular herbs which are associated with severe and sometimes fatal hepatotoxicity: Actaea racemosa, Aloe barbadensis, Atractylis gummifera, Callilepsis laureola, Camellia sinensis, Centella asiatica, Chelidonium majus, Ephedra sinica, Garcinia cambogia, Hypericum perforatum, La...

Sweeteners play a vital role in the food industry serving either as preservative or addition to consumables. The high intake of sweetener brought about production artificially synthesized which has, turn, given reason concern for health on long term. Cassava is one mostly cultivated crops Nigeria with cassava possessing highest level starch compared other crops. This research explores abundance...
