Commodity risk assessment of Alnus cordata, Alnus glutinosa and Alnus incana plants from the UK
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘high‐risk plants, plant products and other objects’. Taking into account the available scientific information, including the technical information provided by ...

Characteristics of Resistance to Puccinia coronata f. sp. avenae in Avena fatua.
Crown rust, caused by Puccinia coronata f. sp. avenae, is the most widespread and harmful fungal disease of oat. The best defense against the pathogen is use of cultivars with genetic resistance, which is effective, economic, and an environmentally ...

High quantities of light received by wheat seedlings alters the profile of volatile organic compounds, which in turn enhances germination and infection efficiency of Puccinia striiformis. Abstract Many factors are known to influence infection by cereal rusts, including environmental variables such at light, humidity and temperature, the topography of ...

Abstract The barley powdery mildew disease caused by the biotrophic fungus Blumeria hordei (Bh) poses enormous risks to crop production due to yield and quality losses. Plants and fungi can produce and release volatile organic compounds (VOCs) that serve as signals in plant communication and defense response to protect themselves.

Abstract Understanding the trade‐offs between improving turfgrass performance and seed production capacity would improve acceptance and accelerate the release of new perennial ryegrass (Lolium perenne L.) cultivars. An experiment was designed to measure the turfgrass quality, seed yield, and component traits among 20 perennial ryegrass entries grown in

Apoptotic Cell Death is a Common Response to Pathogen Attack in Oats
We have examined the characteristics of cell death induced by pathogen infection in oats with respect to following hallmark apoptotic features: DNA laddering, chromatin condensation, and electron microscopic-bterminal deoxynucleotidyl transferase ...

The complex relationship between disease resistance and yield in crops
Summary In plants, growth and defence are controlled by many molecular pathways that are antagonistic to one another. This results in a ‘growth‐defence trade‐off’, where plants temporarily reduce growth in response to pests or diseases. Due to this antagonism, genetic variants that improve resistance often reduce growth and vice versa.

Species of macrocyclic, heteroecious grass rusts often have been defined with wide host ranges and variation in spore morphology. Consequently, some are species complexes and contain genetically distinct forms. Molecular analyses, together with morphological and biological methods, provide powerful means to dissect these complexes. Puccinia coronata is
