Title

Dieback and mortality of South African fynbos shrubs is likely driven by a novel pathogen and pathogen‐induced hydraulic failure

ANNA L. JACOBSEN; FRANCOIS ROETS; SHAYNE M. JACOBS; et al. Austral Ecology 2011. doi:10.1111/j.1442-9993.2011.02268.x

Other claims from this paper (7)

Association Plants with over 60% crown dieback had water potentials as low as −12 MPa.
Association Pythium was isolated from root vascular tissue of all stressed plants and absent from healthy plants.
Mechanism Pathogen effects were considered the proximate cause of stress.
Mechanism Extreme water stress was considered the ultimate cause of death.
Association Brunia may be susceptible to Pythium infection.
Association Leucadendron may be susceptible to Pythium infection.
Association Erica may be susceptible to Pythium infection.
