Abstract:

Phosphite has been used to effectively control the soil borne plant pathogen Phytophthora cinnamomi in many horticultural crops, forest trees and natural ecosystems. However, the molecular mechanisms behind phosphite action on this pathogen are poorly understood. Several studies have shown that phosphite inhibits growth and zoospore production of P. cinnamomi and in addition induces significant physiological and metabolic changes in the mycelium. As an approach to understanding the mechanisms and relevance of these changes in the pathogen, the effect of phosphite on gene expression was inve

Phytophthora cinnamomi Rands is a common and devastating pathogen of cultivated proteas worldwide. Webb (1997) described a Sudden Death plant disease of proteas in Western Australia (WA) protea plantations. Proteas that suffer the syndrome display symptoms such as stunted growth, wilting, chlorosis and often death. In the current study, a number of protea plantations in the southwest of WA were visited to quantify the extent that P. cinnamomi was attributing to deaths of cultivated proteas. The survey indicated that P. cinnamomi is the major cause of Sudden Death in proteas. A range of ot

The avocado (Persea americana Mill.) is an economically important crop worldwide. The most important disease of avocado is Phytophthora root rot, which is caused by Phytophthora cinnamomi Rands. Currently, phosphonate trunk injections provide satisfactory disease control; however, the possibility of reduced sensitivity and eventually resistance to this fungicide is lurking on the horizon. Furthermore, consumer demands for “organic” fruit has been increasing over the past decade, emphasising the need to use root rot-resistant rootstocks.

However, P. cinnamomi was isolated from a sub-alpine area ‘Barrington Tops National Park’ in the 1990s. Subsequent Australia wide surveys detected 68 Phytophthora species in Australia. Of these, 33 Phytophthora species, including P. cinnamomi, were detected in the alpine and sub-alpine areas on Kosciuszko National Park (KNP) alone. This suggested that Phytophthora species had adapted to cold environments. This project inve

Phytophthora cinnamomi (Rands) is one of the world’s most invasive plant pathogens and accurate diagnosis of its presence in plants and soil using molecular tools is very important. Few of the existing primers were found to discriminate between P. cinnamomi and a number of newly described species, and for those that could do so, the sensitivity was inadequate. Further, for my research, primers to detect both DNA and RNA were required, and the existing primers based on non-protein coding gene regions were inappropriate. New primers were developed based on the cytochrome oxidase subunit 2 (cox2)

Phytophthora cinnamomi is a plant pathogen that causes dieback disease in southern Australia. It threatens the biodiversity of many natural ecosystems due to the susceptibility of the native vegetation. If methods of control are to be successful then we must appreciate the genetic variation in the pathogen and the ways in which this variation is generated. Previously, the only genetic markers available to study P. cinnamomi were isozymes, which showed that isolates in Australia were one of three isozyme types.

Abstract:

Um total de 49 isolados de Phytophthora spp. associados com a doença da tinta do castanheiro foram obtidos, pelos métodos clássicos de isolamento, em diferentes situações de crescimento do castanheiro na região Norte de Portugal: viveiros, plantações jovens, soutos adultos e do solo. Os isolados de Phytophthora foram identificados por PCR-RFLP da região ITS-rDNA amplificada pelos “primers” universais ITS6 (Cooke & Duncan, 1997) e ITS4 (White et al., 1990). A restrição enzimática do fragmento amplificado foi realizada com as enzimas Alu I, Msp I e Taq I cujo perfil de restrição permite a

Abstract:

One of the major aims of the research presented in this thesis was to assist managers of native vegetation communities in southeastern Australia in understanding the dynamics of P. cinnamomi with an important ecological species, Xanthorrhoea australis. It trialed the use of phosphite in large-scale field applications to establish the usefulness of this management option for the first time on Victorian flora. This thesis describes the process of disease development within mature X. Australia plants. For the first time it was shown that within X. australis plants, secondary disease symptoms ar

Abstract:

Diseases in natural ecosystems are often assumed to be less severe than those observed in domestic cropping systems due to the extensive biodiversity exhibited in wild vegetation communities. In Australia, it is this natural biodiversity that is now under threat from Phytophthora cinnamomi. The soilborne Oomycete causes severe decline of native vegetation communities in south-western Victoria, Australia, disrupting the ecological balance of native forest and heathland communities. While the effect of disease caused by P. cinnamomi on native vegetation communities in Victoria has been extensive

Abstract:

Avocado (Persea americana Mill.) is an important crop whose cultivation is severely threatened by Phytophthora cinnamomi Rands. The South African avocado industry makes an important contribution to the world’s avocado supply, and is one of the world’s largest exporters. If the current Phytophthora root rot problem is not addressed soon, the losses encountered by the avocado industry may become so extensive that it results in job losses. The scant information that is available for P. cinnamomi interaction studies indicate that there is no gene-for-gene interaction yet described between th

Abstract:

Phosphite (Phi), an analogue of phosphate (Pi) is highly effective for the control of Phytophthora cinnamomi, a devastating necrotrophic pathogen worldwide. This study describes the effect of phosphite (Phi) on the induction of defence responses in Phytophthora cinnamomi-infected Arabidopsis thaliana accessions Ler and Col-0, and mutants defective in salicylic acid (SA), jasmonic acid (JA), ethylene (ET), abscisic acid (ABA), phosphate starvation response (PSR) and auxin response signalling pathways. The inoculation of the resistant Col-0 with P. cinnamomi induced a rapid increase in callose d

Abstract:

The overall aim of this project was to screen actinomycetes for the ability to produce antibiotics inhibitory to P. cinnamomi in vitro. Some of the more promising isolates were then screened in vivo in a glasshouse pot-trial. The actinomycete isolates used had been previously isolated from jarrah forest soils suppressive to P. cinnamomi, ie. areas where P. cinnamomi was present in the soil but there was little evidence of disease. They had been isolated using dry heat pretreatments ( 120°C for one hour) designed to select for less frequently isolated actinomycetes especially the genus Microbis

Abstract:

Phytophthora cinnamomi has been recognised as a key threatening process to Australias biodiversity by the Commonwealths Environment Protection and Biodiversity Conservation Act 1999. Despite over 80 years of extensive research, its exact mode of survival is still poorly understood. It is widely accepted that thin- and thick-walled chlamydospores are the main survival propagules while oospores are assumed to play no role in the survival of the pathogen in the Australian environment, yet evidence is limited. The saprophytic ability of the pathogen is still unresolved despite the important r

A Doença da Tinta do Castanheiro, é considerada como uma das principais causas do desaparecimento dos soutos. Phytophthora cinnamomi e P. cambivora são as duas espécies associadas à Doença da Tinta do Castanheiro, sendo P. cinnamomi a espécie preponderante na doença da tinta em Portugal. Os agentes patogénicos que causam a Doença da Tinta no Castanheiro provocam uma situação de difícil solução, pois estes possuem formas de sobrevivência e de disseminação que lhes permite manterem-se no solo quase indefinidamente.
