Existence of a recombinant between Tomato yellow leaf curl Sardinia and Tomato yellow leaf curl begomoviruses
In Spain, Tomato yellow leaf curl Sardinia and Tomato yellow leaf curl begomoviruses (EPPO A2 quarantine pests) both occur. Studies revealed the existence of a recombinant between these two viruses. It was isolated from bean plants (Phaseolus vulgaris) showing symptoms of leaf crumple, collected in Almería (south-eastern Spain) in 1999. The biological and epidemiological consequences of the presence of this new interspecific recombinant have yet to be determined.
