Nitric Oxide and Reactive Oxygen Species Do Not Elicit Hypersensitive Cell Death but Induce Apoptosis in the Adjacent Cells During the Defense Response of Oat

Molecular Plant-Microbe Interactions, 2004
Nitric oxide (NO) acts as a signaling molecule in many cellular responses in plants and animals. Oat plants (Avena sativa L.) evoke the hypersensitive response (HR), which shares morphological and biochemical features with mammalian apoptosis, such as ...

Crown Rust Development and Selection for Virulence in Puccinia coronata f. sp. avenae in an Oat Multiline Cultivar [PDF]

Plant Disease, 2009
Crown rust, caused by Puccinia coronata f. sp. avenae is the most important disease of cultivated oat in North America. Numerous race-specific (Pc) genes for crown rust have been found in Avena spp. but this type of resistance has not been durable when used in oat cultivars.

Yellow rust infection of wheat: How the quantity of light received by wheat seedlings before inoculation affects infection efficiency

Plant Pathology, Volume 73, Issue 9, Page 2359-2371, December 2024.
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 ...

Optimizing an integrated biovigilance toolbox to study the spatial distribution and dynamic changes of airborne mycobiota, with a focus on cereal rust fungi in western Canada

Molecular Ecology Resources, Volume 24, Issue 6, August 2024.
Abstract In the face of evolving agricultural practices and climate change, tools towards an integrated biovigilance platform to combat crop diseases, spore sampling, DNA diagnostics and predictive trajectory modelling were optimized. These tools revealed microbial dynamics and were validated by monitoring cereal rust fungal pathogens affecting wheat ...

Two types of biplots to integrate multi‐trial and multi‐trait information for genotype selection

Crop Science, Volume 64, Issue 3, Page 1608-1618, May/June 2024.
Abstract Genotype × environment interaction (GE) and unfavorable associations among breeding objectives are the two key challenges in genotype evaluation and selection. Dealing with GE includes utilizing repeatable GE and accommodating nonrepeatable GE, and analytical tools for both steps have been developed in recent years.
