Phytophthora root and stem rot – new disease of Ilex aquifolium "Myrtifolia” in Poland

Acta Mycologica, 2014
Phytophthora cinnamomi was often isolated from rotted roots and stems of English holly "Myrtifolia" together with Alternaria alternata, Cylindrocarpon destructanss, Fusarium avenaceum and other fungal species. Inoculation of leaf blades and stem parts of

Growth, infection and aggressiveness of Phytophthora pathogens on Rhododendron leaves

CABI Agriculture and Bioscience, 2021
Background Phytophthora species are well known as important or emerging pathogens. The genus Rhododendron is of considerable importance to plant regulatory agencies because it is host to many Phytophthora species, most notably, P.

Phytophthora cinnamon causing stem canker and root rot of nursery-grown Platanus × acerifolia: first report in the Northern emisphere

Phytopathologia Mediterranea, 2014
Lethal stem and root cankers were observed in nursery-grown Platanus × acerifolia trees in Rome. Externally, canker lesions appeared as bluish or blackish areas starting from the stem base and extending upward. Inner bark was necrotised. In some cases an

Stand Age, Standard Retention Density and Site Conditions as Drivers of Shoot Biomass Accumulation in Mediterranean Oak Coppices

Land Degradation &Development, EarlyView.
ABSTRACT Mediterranean oak coppices represent an important fuelwood resource in Central Italy, but management decisions are often constrained by limited quantitative evidence on the relative importance of stand development, standard retention, site conditions, and climate in driving shoot biomass accumulation.

Ethnobotanical and genetic assessments of Central American avocado landraces reveal novel sources of biodiversity and ancient migration patterns

PLANTS, PEOPLE, PLANET, EarlyView.
Avocados are a multibillion‐dollar global commodity, but their growing export market pressures local farmers to abandon local fruit tree diversity in favor of commercial cultivar production. Interviews with rural avocado farmers and households from the Southern Mexican Highlands, Pacific Coastal Honduras, and Western Nicaragua, as well as the genetic ...

Occurrence of Phytophthora cinnamomi in the Rhizosphere of Declining Leucadendron elimense subsp. salteri in South Africa

Forest Pathology, Volume 56, Issue 4, August 2026.
ABSTRACT Phytophthora cinnamomi is a destructive invasive plant pathogen reported from more than 5000 hosts and across all continents except Antarctica. In South Africa, P. cinnamomi poses a substantial threat to native flora, particularly members of the Proteaceae.

Expression of defence-related genes against Phytophthora cinnamomi in five avocado rootstocks

South African Journal of Science, 2013
Avocado (Persea americana) – a major fruit crop worldwide – is threatened by root rot caused by Phytophthora cinnamomi. This pathogen is known to infect the plant via the feeder roots leading to branch dieback, and eventually tree mortality.

Tracking Vegetation Response to Planned Burning in a Heathy Woodland

Austral Ecology, Volume 51, Issue 7, July 2026.
ABSTRACT Wildfires are predicted to become more frequent and intense with climate change. In conjunction, the use of fuel reduction burning is increasing to manage and mitigate wildfire risk. For vegetation communities with strong fire‐cued recruitment and regeneration responses, changes to historical fire regimes are anticipated to alter patterns of ...

Host Range and Disease Potential of Colletotrichum aotearoa in Australian Native Plants

Plant Pathology, Volume 75, Issue 4, July‐August 2026.
The broad host range of Colletotrichum aotearoa (including several Banksia species), together with its ability to cause asymptomatic infection, suggests that it may be an important pathogen of Australian native plants. ABSTRACT Colletotrichum aotearoa, originally described from various native species in New Zealand, has since been reported in Australia

Identification of an Elicitin Gene Cluster inPhytophthora Cinnamomi

DNA Sequence, 1998
Elicitins are a group of highly conserved proteins secreted by species of Phytophthora and a species of the related genus Pythium, Pythium vexans. Some of these proteins act as inducers of the necrotic hypersensitive-like response and the associated systemic acquired resistance phenomenon, in some species.
