Trehalose is a nonreducing α,α-1,1-disaccharide in a wide range of organisms, and has diverse biological functions that range from serving as an energy source to acting as a protective/signal sugar. However, significant amounts of trehalose have rarely been detected in higher plants, and the function of trehalose in the drought-tolerant crop cassava (Manihot esculenta Crantz) is unclear. We mea...

Résumé Research Application Summary Advances in cassava research in management of Cassava Brown Streak Virus

Cassava brown streak disease (CBSD) was first observed on cassava (Manihot esculenta) in Rwanda in 2009. In 2014 eight major cassava-growing districts in the country were surveyed to determine the distribution and variability of symptom phenotypes associated with CBSD, and the genetic diversity of cassava brown streak viruses. Distribution of the CBSD symptom phenotypes and their combinations v...

a research was conducted to evaluate cassava production by women farmers in igbo-eze north local government area of enugu state, nigeria. one hundred and twenty smallholder female cassava farmers were selected using multi-stage sampling. data were collected from the respondents using questionnaire and interview schedule. then descriptive statistics (mean, frequency and percentage) were used in ...

This study aimed at evaluating the impact of seasons on nutritional status and dietary cassava-related cyanide exposure in Burhinyi Idjwi, two areas eastern Democratic Republic Congo, witnessing similarly high cassava-derived poisoning but differently affected by konzo malnutrition. Cyanide content cassava roots flour, urinary thiocyanate levels (uSCN) 54 subjects (40 from 14 aged 28.7 (12.1) y...

BACKGROUND Beyond nutritional values are the pharmacological potentials of cassava comparative with other staple carbohydrate plant-based foods such as wheat. The knowledge of applicability to diabetes and its cardiovascular complications management seems not just limited but unacknowledged. As a preliminary study, a community's knowledge of pharmacological value of cassava is investigated. M...

Our ability to manage gene flow within traditional agroecosystems and their repercussions requires understanding the biology of crops, including farming practices' role in crop ecology. That these practices' effects on crop population genetics have not been quantified bespeaks lack of an appropriate analytical framework. We use a model that construes seed-management practices as part of a crop'...

Eight crossbred (75% Holstein Friesian) cows in mid-lactation were randomly assigned to a switchback design with a 2x2 factorial arrangement to evaluate two nonstructural carbohydrate (NSC) sources (corn meal and cassava chips) with different rumen degradability and used at two levels of NSC (55 vs. 75%) with protein source (supplied by urea in the concentrate mix). The treatments were 1) Low d...

Cassava (Manihot esculenta Crantz) is a highly productive tuber crop growing on marginal land, providing rural communities in India with nutritious food, as well as income generated by huge industrial demand for sago and starch. In Tamil Nadu (TN) alone it supports over 10,000 smallholder farmers. To sustain the livelihoods of this community of smallholder farmers, the Indo-Swiss Collaboration ...
