It is currently grown widely also on other D, Mwaipopo B, RajamaÈki M-L, Nchimbi-Msolla S, continents including Africa. We surveyed seedborne viruses in new common bean varieties et al. (2017) Pathogenic seedborne viruses are rare but Phaseolus vulgaris endornaviruses are introduced to Nicaragua (Central America) and in landraces and improved varieties grown in common in bean varieties grown in Nicaragua and Tanzania (eastern Africa). Bean seeds, harvested from Nicaragua and Tanzania, were Tanzania. PLoS ONE 12(5): e0178242. https://doi. grown in insect-controlled greenhouse or screenhouse,
