Temporal dynamics of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine interspecific competition and disease development on oilseed rape

open access: yesPest Management Science, EarlyView.
This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...

Cinnamom verum Plantations in the Lowland Tropical Forest of Mexico Are Affected by Phytophthora cinnamomi, Phylogenetically Classified into Phytophthora Subclade 7c

open access: yesHorticulturae, 2023
Cinnamon is a tree introduced to the lowlands of Mexico in the mid-16th century, but it spread to other places at the beginning of the 20th century due to its important commercial value as an aromatic spice.

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

open access: yesPest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

Decreased DMI sensitivity of Plenodomus biglobosus (phoma of oilseed rape) associated with CYP51 substitution G476S

open access: yesPest Management Science, EarlyView.
Here, we report for the first time a target site mutation in the CYP51 gene of the oilseed rape phoma stem canker fungus Plenodomus biglobosus (Leptosphaeria biglobosa) that is associated with decreased sensitivity to sterol demethylation inhibitor fungicides.

Phytophthora ilicis as a leaf and stem pathogen of Ilex aquifolium in Mediterranean islands

open access: yesPhytopathologia Mediterranea, 2014
Between 2010 and 2013 several English holly trees showing defoliation, leaf and twig blight were found in natural ecosystems in Sardinia and Corsica. A Phytophthora species was consistently isolated from necrotic tissues of leaves and twigs, and bleeding

A suitable approach to resource allocation in biosecurity when considering dependent benefits and costs

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Optimal allocation of resources to the management of biosecurity risk, threatened species conservation or natural hazards such as bushfires is imperative—because program budgets are usually finite and, therefore, constrained. However, effectively dividing resources among management activities to achieve the greatest benefit remains a ...

Antibacterial efficacy of metals in preventative and therapeutic equine podiatry applications

open access: yesEquine Veterinary Education, EarlyView.
Summary Background Thrush, abscesses, white line disease and cankers are life‐threatening infections common in equine hooves. Copper has a history of medicinal use on equine hooves. There is a paucity of scientific evidence supporting the use of metals as antimicrobial agents in equine podiatry.

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

open access: yesThe FEBS Journal, EarlyView.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Poplar miR1447 Is a Negative Regulator of Disease Resistance Through the SA‐Dependent Pathway

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Although microRNA1447 (miR1447) regulates poplar responses to abiotic stress and pest infestation, how miR1447 regulates poplar immunity against pathogens and its underlying molecular mechanisms remain to be elucidated. Here, we revealed that miR1447 functioned as a negative regulator of poplar disease resistance against fungal and bacterial ...
