| Popis: | The main region for producing fresh beans in Europe is located in the provinces of Almería and Granada in south-eastern Spain, where over 100,000 Tm are produced in 6,000 ha of plastic greenhouses. However, since 2003 bean crops exhibit interveinal yellowing symptoms, which develop within a few weeks after the appearance of the whitefly vector Bemisia tabaci. Leaves become thickened and crispy, and decreased fruit number and plant longevity lead to production losses up to 50-100% causing farmers to abandon bean production in greenhouses. Based on the host range, the symptoms produced, the presence of a high molecular weight double stranded (ds) RNA doublet in diseased host tissue, reminiscent of the bipartite genome of criniviruses, and the nucleotide sequence of part of this whitefly-transmissible agent, a new proposed crinivirus species was identified and named Bean yellow disorder virus (BnYDV). |
