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

The grapevine microbiota: A review on the possible impacts of plant protection programs on phyllosphere microorganisms

open access: yesAnnals of Applied Biology, EarlyView.
This review highlights recent advances in understanding how plant protection programs and alternative fungicides affect the taxonomic composition of the grapevine phyllosphere microbiota. Bacterial and fungal communities are primarily shaped by the plant compartment, vineyard location, and sampling time. Plant protection programs generally have a minor

Bark-inhabiting fungal communities of European chestnut undergo substantial alteration by canker formation following chestnut blight infection

open access: yesFrontiers in Microbiology, 2023
BackgroundChestnut forests are severely threatened by chestnut blight caused by the fungal pathogen Cryphonectria parasitica and the infected trees exhibit bark canker in the later stage of the disease.

The tree‐parasitic fungus Cryphonectria carpinicola discovered on European chestnut and European hornbeam in Azerbaijan

open access: yesEPPO Bulletin, EarlyView.
Abstract The ascomycetous fungus Cryphonectria carpinicola is typically found in its asexual form on the European hornbeam, and its sexual state has only recently been discovered in deadwood of different Carpinus species in Japan. Recently, this fungus has been added to the EPPO Alert List due to its increasing incidence in the EPPO region and a ...

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 ...

MdRLKT1–MdRAX2–MdMKS1 Module Positively Regulating Resistance to Cytospora mali in Apple

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Valsa canker (caused by Cytospora mali = Valsa mali. C. mali) is one of the most destructive diseases affecting apple cultivation. The scarcity of natural germplasm resources with high resistance and immunity underscores the importance of exploring plant immune regulation factors of disease‐resistant breeding.

ZmWRKY29 Transcriptionally Represses ZmRBOHC to Attenuate ROS Production and Facilitates Gibberella Stalk Rot Susceptibility in Maize

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Gibberella stalk rot (GSR), caused by the fungal pathogen Fusarium graminearum, severely threatens maize production. However, the molecular mechanisms underlying maize resistance to GSR remain poorly understood. Here, we have identified ZmWRKY29 as a transcriptional repressor induced by F.
