Emergência e vigor de plântulas de genótipos de feijão-caupi sob estresse salino Emergence and seedling vigor of cowpea genotypes under salt stress

Revista Brasileira de Engenharia Agrícola e Ambiental, 2012
Objetivou-se, com este trabalho, avaliar o efeito da salinidade da água de irrigação no feijão-caupi e identificar genótipos tolerantes ao estresse salino nos estádios iniciais do seu desenvolvimento. Os níveis de condutividade elétrica da água foram: 0;

Identification of type III effectors modulating the symbiotic properties of Bradyrhizobium vignae strain ORS3257 with various Vigna species

Scientific Reports, 2021
The Bradyrhizobium vignae strain ORS3257 is an elite strain recommended for cowpea inoculation in Senegal. This strain was recently shown to establish symbioses on some Aeschynomene species using a cocktail of Type III effectors (T3Es) secreted by the ...

Evolutionary patterns and structural divergence of CENH3 in legumes: Implications for haploid induction breeding

Grassland Research, EarlyView.
From structure to application: evolutionary insights and genome editing strategies for CENH3‐mediated haploid induction in legumes. Abstract Background The centromeric histone variant CENH3 is crucial for chromosome segregation and haploid induction in plants, yet its evolutionary patterns in legumes remain poorly characterized. Methods We investigated

Wild Legume Species in Africa: A Synthesis of Vigna Potential for Nutrition and Food Security

Legume Science
Legumes are staple foods and essential sources of nutrients for populations facing food insecurity in Africa. Within this group, the genus Vigna—including cowpea (Vigna unguiculata subsp. unguiculata)—is among the most widely cultivated and consumed. Yet,

Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

Animal Conservation, EarlyView.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Food without fire: Environmental and nutritional impacts from a solar stove field experiment

American Journal of Agricultural Economics, EarlyView.
Abstract Over 80% of the population in rural Sub‐Saharan Africa relies on biomass cooking fuel, a substantial source of anthropogenic greenhouse gases. We use a field experiment in Zambia to investigate the impact of solar stoves on biomass fuel use and cooking habits.
