Sample preservation and plant sex prediction in white guinea yam (Dioscorea rotundata Poir.)
(2020)Introduction: Yam (Dioscorea spp.) is an economically important staple food in tropical regions, especially for people in West Africa. Understanding of the flowering behavior of the crop to determine potential manipulation available to accomplish crop improvement at early stage remain key challenge in the yam breeding. The methods that reliably yield quality DNA and distinguishing sex type at the early stage of growth have been a challenge in yam genetics and breeding studies. This study assessed ... -
Impact of agricultural programs on youth engagement in agribusiness: a case study
(2020)Using the case of Fadama Graduate Unemployed Youth and Women Support (FGUYS) program, this study assessed the impact of agricultural programs on youth engagement in agribusiness in Nigeria. A total of 977 respondents comprising of 455 participants of the program and 522 non-participants were sampled across three states in Nigeria. Data were analysed using Descriptive and Endogenous Switching Probit Regression (ESPR) Model. The result showed that participation in the program was influenced by age, ... -
Assessment of genetic diversity of Dioscorea praehensilis (Berth.) collected from central region, Ghana using simple sequence repeat (SSR) markers
(2020-03)Dioscorea praehensilis Berth is one of the wild yam species resistance to many yam disease (yam anthracnose disease and yam mosaic virus) grow in Ghana especially in the cocoa grown regions of the country. It is a crucial crop that has been known to contribute to poverty reduction and food gap. Genetic diversity in this yam species has been discovered to be eroding and neglected. In this study we evaluated the genetic diversity among 43 D. praehensilis collected from Ghana using simple sequence ... -
ABC transporter genes ABC-C6 and ABC-G33 alter plant-microbeparasite interactions in the rhizosphere
(2019)Plants are master regulators of rhizosphere ecology, secreting a complex mixture of compounds into the soil, collectively termed plant root exudate. Root exudate composition is highly dynamic and functional, mediating economically important interactions between plants and a wide range of soil organisms. Currently we know very little about the molecular basis of root exudate composition, which is a key hurdle to functional exploitation of root exudates for crop improvement. Root expressed transporters ... -

Survey of wild Vigna in southern Africa
(1991)In 1988 collecting and expeditionsto Southern Africa gathered valuable genetic diversity of wild species of Virgna. A remarkable amount of variability is present in the samples of V. Unguiculata (L.) Walp. Collected in Swaziland and the Republic of South Africa. The data collected, together with information gathered on previous collecting expeditions, strongly support the theory that Southern Africa is the centre of origin for section Catjang of this species. -

Institutionalising dialogue in Rwanda through innovation platforms
(2016-03)A platform of farmers, retailers and service providers,civil society organisations, NGOs, government officials, and researchers improves livelihoods in Rwanda. Through interaction and collaboration, these groups experiment with various technological and institutional innovations, thereby tackling local agricultural challenges. This experience illustrates the importance of institutionalising a space where knowledge can be co-created. -
