Enhanced Outcrossing, Directional Selection and Transgressive Segregation Drive Evolution of Novel Phenotypes in Hybrid Swarms of the Dutch Elm Disease Pathogen Ophiostoma novo-ulmi

Journal of Fungi, 2021
In the 1970s, clones of the two subspecies of Ophiostoma novo-ulmi, subsp. americana (SSAM) and subsp. novo-ulmi (SSNU) began to overlap in Europe, resulting in hybrid swarms.

Functional Expression of the Gene cu, Encoding the Phytotoxic Hydrophobin Cerato-ulmin, Enables Ophiostoma quercus, a Nonpathogen on Elm, to Cause Symptoms of Dutch Elm Disease

Molecular Plant-Microbe Interactions, 2000
We studied the involvement of the phytotoxic hydrophobin cerato-ulmin (CU) in pathogenesis and virulence of Dutch elm disease (DED) by expressing its encoding gene (cu) in Ophiostoma quercus, a nonpathogenic species on elm closely related to the DED ...

Genomics of the Dutch elm disease pathosystem: are we there yet?

iForest - Biogeosciences and Forestry, 2015
During the last decades, the development of ever more powerful genetic, molecular and omic approaches has provided plant pathologists with a wide array of experimental tools for elucidating the intricacies of plant-pathogen interactions and proposing new

Priming of Plant Defenses against Ophiostoma novo-ulmi by Elm (Ulmus minor Mill.) Fungal Endophytes

Journal of Fungi, 2021
Some fungal endophytes of forest trees are recognized as beneficial symbionts against stresses. In previous works, two elm endophytes from the classes Cystobasidiomycetes and Eurotiomycetes promoted host resistance to abiotic stress, and another elm ...

The sleeping giant needs coffee: Overlooked areas for integrating plant ecophysiology and evolutionary biology. [PDF]

Am J Bot
Abstract Interpretations of evolutionary outcomes are limited without incorporation of physiological ecology, and ecophysiological interpretations would benefit from incorporating evolutionary perspectives. Although there has been a rise of studies in the last 20 years between these fields, evolutionary studies that incorporate plant physiology have ...

Structural investigation of human U6 snRNA recognition by spliceosomal recycling factor SART3 RNA recognition motifs. [PDF]

FEBS J
Human SART3 has two RRM domains to engage with U6 snRNA for spliceosome recycling. This study reports solution structures of SART3 RRM domains and investigates the interaction between RRM and U6 snRNA. SART3 binds to the asymmetric bulge of U6 snRNA as a dimer via conserved positively charged surfaces.

Susceptibility of native French elm clones to Ophiostoma novo-ulmi [PDF]

Annals of Forest Science, 2005
Plus de 200 clones d'ormes indigènes en Europe (U. minor, U. glabra et leurs hybrides et U. laevis) ont été inoculés avec Ophiostoma novo-ulmi en comparaison avec quelques cultivars sur deux sites et au cours de six séries d'inoculations. Le pourcentage de flétrissement ou de défeuillaison a été estimé l'année de l'inoculation, et la guérison ou la ...

Machine learning-based spectral and spatial analysis of hyper- and multi-spectral leaf images for Dutch elm disease detection and resistance screening

Artificial Intelligence in Agriculture, 2023
Diseases caused by invasive pathogens are an increasing threat to forest health, and early and accurate disease detection is essential for timely and precision forest management.
