Space and resource use by American crow Corvus brachyrhynchos in an area endemic for chronic wasting disease

open access: yesWildlife Biology, EarlyView.
American crow Corvus brachyrhynchos is a common species throughout North America. Crows play a role in the ecology of multiple diseases and a single laboratory experiment has shown the potential for crows to pass infectious prions, such as those associated with chronic wasting disease (CWD), in their feces after being force‐fed with infected material ...

The role of Phytophthora multivora in Eucalyptus gomphocephala (tuart) woodland decline [PDF]

open access: yes, 2011
Since the 1990’s Eucalyptus gomphocephala (tuart) has been suffering a significant decline in Yalgorup National Park, approximately 100 km south of Perth Western Australia. Symptoms range from chronic deterioration to sudden mass collapse.

Evaluating a structured expert elicitation approach for adaptive conservation management based on lessons from five years in practice

open access: yesConservation Biology, EarlyView.
Abstract Adaptive management of threatened species relies on having ex ante estimates of species’ responses to different interventions. Structured expert elicitation is often used to generate these estimates, but comparisons of these expert‐predicted outcomes with observed results are rare.

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

open access: yesJournal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

The TaRNS4–TaPP2C10 module regulates wheat resistance to stripe rust through RNA degradation and MAPK cascades

open access: yesJournal of Integrative Plant Biology, EarlyView.
In wheat, phosphorylation of the S‐like RNase TaRNS4 mediated by the kinase TaRLK5 promotes its degradation of Puccinia striiformis f. sp. tritici RNA in the apoplast, enhancing resistance to stripe rust. TaRNS4 can hijack phosphatase TaPP2C10 to relieve its dephosphorylation of TaMAPK6, thereby activating MAPK‐mediated immune responses. ABSTRACT RNase

Management of Phytophthora cinnamomi for biodiversity conservation in Australia: Part 2. National best practice guidelines [PDF]

open access: yes, 2005
Disease in natural ecosystems of Australia, caused by the introduced plant pathogen Phytophthora cinnamomi, is listed as a key threatening process under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act).

Disruption of OsMAPKKK24 activation by the Xanthomonas oryzae effector XopY leads to compromised disease resistance in rice

open access: yesJournal of Integrative Plant Biology, EarlyView.
The kinase OsRLCK55 phosphorylates OsMAPKKK24 to positively regulate rice resistance against Xanthomonas oryzae. To compromise this defense, the effector XopY targets OsMAPKKK24 and suppresses its autophosphorylation and the transphosphorylation mediated by OsRLCK55, ultimately leading to reduced disease resistance.

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

open access: yes, 2008
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.

Phytophthora Disrupts Plant Immunity by Manipulating Nitric Oxide Homeostasis Through GSNOR Inhibition

open access: yesAdvanced Science
Nitric oxide (NO), a pivotal redox signaling molecule, coordinates plant development and immune responses through S‐nitrosylation‐mediated protein modification. While NO‐dependent S‐nitrosylation fine‐tunes immune responses, whether pathogens hijack this

Avirulence genes of Magnaporthe oryzae are a pathogen defense arsenal shaped by cognate rice resistance genes in the field

open access: yesNew Phytologist, EarlyView.
Population structure and AVR gene presence/absence of 383 single‐spore isolates from the US Mo population. Summary We examined the frequency of and variation in eight avirulence (AVR) genes from 840 Magnaporthe oryzae field isolates collected from the Southern United States relative to rice resistance (R) genes deployed from 1959 to 2017. Little coding
