Phytophthora ramorum infection of coast live oak leaves in Californian forests and its capacity to sporulate in vitro

Vettraino, A.M., Hüberli, D. and Garbelotto, M. (2008) Phytophthora ramorum infection of coast live oak leaves in Californian forests and its capacity to sporulate in vitro. Australasian Plant Pathology, 37 (1). pp. 72-73.

Abstract

Coast live oak (Quercus agrifolia) is a known host for Phytophthora ramorum, the casual agent of sudden oak death in California, with symptoms expressed as necrotic stem cankers. In the forest, leaves on two saplings in California were found to be infected with P. ramorum and these were associated with infected bay laurel (Umbellularia californica) trees. Coast live oak leaves supported sporulation and produced chlamydospores in vitro. This is the first report to identify foliage of coast live oak as a source of infection of P. ramorum in the forest and its confirmation in in vitro inoculations.
