Summary: | Isolations from diseased plants and controlled inoculations indicate that the host range of the canker pathogen
Luteocirrhus shearii
is mainly limited to
Banksia.
Branches exhibiting canker symptoms were sampled from the Geraldton Sandplains, Swan Coastal Plain, Jarrah Forest, Warren and Esperance Sandplains bioregions of the South-West Botanical Province of Western Australia (
n
= 1,351).
Luteocirrhus shearii
was isolated from only Proteaceae and did not infect wound inoculated Myrtaceae. The pathogen was isolated from or formed extensive lesions in 15
Banksia
species. Differences in isolation frequency and rates of lesion extension of
L. shearii
between
Banksia
spp. may indicate different modes of infection by the canker pathogen. By exerting top-down control of population dynamics of
Banksia
communities from lower trophic levels,
L. shearii
would substantially alter host species diversity and in turn ecosystem processes. Predicted climate change could influence future biotic reorganisations following
L. shearii
invasion. What determines the limited host range of
L. shearii
compared to the community of organisms on
Banksia
needs to be determined. |
