Characterization of a new partitivirus isolate in verticillium dahliae provides further evidence of the spread of the highly virulent defoliating (D) pathotype through new introductions

Abstract

Verticilum dahliae is a cosmopolitan soil fungus which causes important vascular diseases in a variety of crops, including olive trees, cotton and horticultural crops. The widespread of a highly virulent defoliating pathotype has greatly increased the threat posed by V. dahliae in certain crops like olive trees.
