Studying tree response to biotic stress using a multi-disciplinary approach: The pine pitch canker case study [PDF]

Frontiers in Plant Science, 2022
In an era of climate change and global trade, forests sustainability is endangered by several biotic threats. Pine pitch canker (PPC), caused by Fusarium circinatum, is one of the most important disease affecting conifers worldwide. To date, no effective

Susceptibility of germinating seedlings of European and Eurasian populations of Pinus sylvestris to damping-off caused by Fusarium circinatum. [PDF]

For Pathol, 2022
Abstract The effect of inoculation with Fusarium circinatum on survival of seed and seedlings of 19 populations of Pinus sylvestris was examined under environmentally controlled conditions, with four treatments (0, 50, 103, 106 spores ml−1). A single seed source of P. radiata was included as a positive control.

Sex Pheromone Receptor Ste2 Orchestrates Chemotropic Growth towards Pine Root Extracts in the Pitch Canker Pathogen Fusarium circinatum [PDF]

Pathogens
In ascomycetous fungi, sexual mate recognition requires interaction of the Ste2 receptor protein produced by one partner with the α-factor peptide pheromone produced by the other partner.

Chromosome-Level Assemblies for the Pine Pitch Canker Pathogen Fusarium circinatum [PDF]

Pathogens
The pine pitch canker pathogen, Fusarium circinatum, is globally regarded as one of the most important threats to commercial pine-based forestry. Although genome sequences of this fungus are available, these remain highly fragmented or structurally ill ...

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda. [PDF]

New Phytol
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

Pest categorisation of <i>Pestalotiopsis disseminata</i>. [PDF]

EFSA J, 2023
Abstract Following the commodity risk assessments of bonsai plants from China consisting of Pinus parviflora grafted on P. thunbergii performed by EFSA, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis disseminata, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae. The pathogen has been reported on

Silent invaders: the hidden threat of asymptomatic phytobiomes to forest biosecurity. [PDF]

New Phytol
Summary Populations of diverse, unknown, and potentially pathogenic fungi and fungus‐like organisms are continuously introduced into new locations via asymptomatic infections (e.g. as endophytes or latent pathogens) within internationally traded live plants.

Co-Infections by Fusarium circinatum and Phytophthora spp. on Pinus radiata: Complex Phenotypic and Molecular Interactions [PDF]

Plants, 2021
This study investigated the complex phenotypic and genetic response of Monterey pine (Pinus radiata) seedlings to co-infections by F. circinatum, the causal agent of pine pitch canker disease, and the oomycetes Phytophthora xcambivora and P.
