Analyses of the in vitro effects of phosphite on Phytophthora cinnamomi isolates
Phytophthora Root Rot, caused by the oomycete Phytophthora cinnamomi (Rands), results in devastating decreases in avocado yields every year. Successful management of P. cinnamomi relies on many features, one of which is chemical control by phosphite. Despite its continuous use in South Africa for …

Identification and expression analysis of putative NLR genes in avocado, Persea americana, during infection by the oomycete, Phytophthora cinnamomi
… Africa is significantly affected by the pathogen Phytophthora cinnamomi. This pathogen causes root necrosis in infected rootstocks, which may ultimately lead to plant death and thus economic losses. The complex molecular interactions between avocado and P. cinnamomi are not well understood and …

The effects of different concentrations of phosphite on ectomycorrhiza formation by Pisolithus tinctorius in Castanea dentata
… and other woody plants caused by the Oomycete Phytophthora cinnamomi. However, phosphite treatments may negatively affect the plant’s ability to form ectomycorrhizas, the mutualistic symbioses between tree roots and certain soil fungi, and the phosphites themselves may be phytotoxic at high …

Aislamiento y caracterización de metabolitos secundarios con actividad inhibidora de oomicetos fitopatógenos.
… el crecimiento del oomiceto fitopatógeno Phytophthora cinnamomi a partir de los productos del metabolismo secundario de la planta Phlomis purpurea y del hongo levaduriforme Trichomonascus vanleenenianus, aislado desde la rizosfera de dicha planta. Estos objetivos fueron alcanzados mediante …

Glucan synthase of Phytophthora sojae
… for glucan synthase activity was done using Phytophthora cinnamomi (Wang and Bartnicki-Garcia, 1976, Selitrennikoff 1995). In this work, the glucan synthase of the oomycete Phytophthora sojae was characterised, solubilized, and partially purified, and the cDNA for a protein co-purifying with …

Food resource availability for Carnaby's cockatoo Calyptorhynchus latirostris on the Swan Coast Plain
… (P < 0.05) reduced by the presence of Phytophthora cinnamomi. In general the number of infructescences significantly (P < 0.05) increased as post-fire age increased. Plant allometric relationships between morphological characteristics and number of infructescences were investigated to …
