Figure 3. Severe symptoms in native plant species inoculated with infective sap containing introduced or indigenous viruses.

A, Severe stunting caused by systemic infection with an introduced generalist virus (Cucumber mosaic virus) in two plants of Anigozanthos manglesii (left) compared with healthy vigorous growth in two mock-inoculated plants of A. manglesii (right); B, Severe plant stunting, apical shoot necrosis and leaf necrosis caused by recent infection with an introduced generalist virus (Tomato spotted wilt virus, TSWV) in three plants A. manglesii (left) compared with healthy vigorous growth in three recently mock-inoculated plants of A. manglesii (right); C, Severe plant stunting, leaf necrosis and leaf chlorosis caused by infection with TSWV in five plants of Solanum symonii (right) compared with healthy vigorous growth in five mock-inoculated plants of S. symoniii (left); D, Systemic necrosis and death caused by infection with an introduced generalist virus (Turnip mosaic virus) in two plants of Trachymene coerulea (front) compared with healthy vigorous growth in two mock-inoculated T. coerulea plants (back); E, Severe stunting caused by systemic infection with an indigenous virus (Clitoria chlorosis virus) in two plants of Kennedia coccinea (right) compared with healthy vigorous growth in two mock-inoculated plants of K. coccinea (left). F, Severe stunting caused by recent systemic infection with an indigenous virus (Passion fruit woodiness virus) in a plant of K. coccinea (right) compared with healthy vigorous growth in a recently mock-inoculated plant of K. coccinea (left).
