Inheritance of resistance to angular leaf spot (ALS) disease caused by Phaeoisariopsis griseola (Sacc.) Ferr was investigated in two common bean cultivars, Mexico 54 and BAT 332. Both Andean and Mesoamerican backgrounds were used to determine the stability of the resistance gene in each of the tw...

Background: Iron is an important micronutrient for all living organisms. Almost 25% of the world population is affected by iron deficiency, a leading cause of anemia. In plants, iron deficiency leads to chlorosis and reduced yield. Both animals and plants may suffer from iron deficiency when thei...

Common bean (Phaseolus vulgaris L.) is an important source of dietary protein and minerals worldwide. Genes conditioning variability for mineral contents are not clearly understood. Our ultimate goal is to identify genes conditioning genetic variation for Zn and Fe content. To establish mapping p...

New bean varieties translate into increased on-farm yields only if farmers obtain access to desired seed. Conventional models of legume seed delivery in Africa, centralized with the National Agricultural Research Systems (NARS), prove to be slow and of limited reach. This article describes a nove...

Bean golden mosaic geminivirus (BGMV) causes major losses on beans (Phaseolus vulgaris) in the tropical and subtropical Americas and the Caribbean Basin. Infectious DNA-A and -B components of BGMV isolates from the Dominican Republic (BGMV-DR) and Guatemala (BGMV-GA) were sequenced, and their gen...

Globally, 800 million people are malnourished. Heavily subsidised farmers in rich countries produce sufficient surplus food to feed the hungry, but not at a price the poor can afford. Even donating the rich world’s surplus to the poor would not solve the problem. Most poor people earn their livin...

Geminiviruses are small plant viruses that encapsidate a single-stranded circular DNA and form double-stranded DNAs in infected plants. Infection of economically important hosts with cloned DNAs of geminiviruses frequently has been difficult. Four isolates of bipartite bean-infecting geminiviruse...

Genetic diversity of populations stored ex situ or in situ can be altered due to the management practices they are subjected to. In this paper, we compare populations of two common bean (Phaseolus vulgaris L.) landraces grown on farms with material collected from the same farms and now kept in tw...
