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

Co-occurring species of Teratosphaeria on Eucalyptus [PDF]
A common leaf spot disease occurring on Eucalyptus cladocalyx and E. lehmannii in the Western Cape Province of South Africa is known from literature to be caused by the fungus Coniothyrium ovatum, which is a pathogen native to several eucalypts in ...

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

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
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
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.

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.
