Figure 2. Symptoms in native plant species inoculated with infective leaf sap containing introduced or indigenous viruses.

A, Large necrotic spot lesions caused by localised infection with an indigenous virus (Clitoria chlorosis virus) in an inoculated leaf of Kennedia coccinea; B, Large necrotic spot local lesions caused by localised infection with an introduced specialist virus (Potato virus X, PVX) in an inoculated leaf of K. coccinea; C, Large necrotic spot local lesions caused by localised infection with an introduced generalist virus (Tomato spotted wilt virus) in an inoculated leaf of Alyogyne huegelii; D, Mild bunching symptoms in young leaves in a plant of Trachymene coerulea caused by systemic infection with an introduced generalist virus (Alfalfa mosaic virus); E, Mild symptoms of necrotic streaking and necrotic leaf markings caused by systemic infection with an introduced specialist virus (PVX) in a plant of Anigozanthos manglesii; F, Mild-moderate stunting caused by systemic infection with an introduced specialist virus (Wheat streak mosaic virus) in plants of Austrostipa compressa (right) compared with more vigorous growth in a mock-inoculated plants (left).
