Wheat powdery mildew, caused by Blumeria graminis f. sp. tritici (Bgt), is a widespread airborne fungal disease which seriously threatens wheat production worldwide. Resistance to the can be lost quickly due limited number of resistance genes in varieties and high variation mildew pathogen. Therefore, it critical explore new breed durable resistant varieties. The objectives this study were eval...

Barley powdery mildew (BPM) is caused by the pathogen Blumeria hordei (Bh) and can lead to severe yield loss. Plant pathologists are looking for new sources of resistance BPM. accessions, including wild subspecies Hordeum vulgare subsp. spontaneum (Hvs), stored in many gene banks often a valuable source economically important characteristics. The barley Hvs could be aim presented investigation ...

Cell death regulation is linked to pathogen defense in plants and animals. Execution of apoptosis as one type of programmed cell death in animals is irreversibly triggered by cytochrome c release from mitochondria via pores formed by BAX proteins. This type of programmed cell death can be prevented by expression of BAX inhibitor 1 (BI-1), a membrane protein that protects cells from the effects ...

Honey bees face new challenges, ranging from climate crisis to emerging pathogens such as Vairimorpha (Nosema) ceranae that synergistically cause a syndrome designated colony collapse disorder (CCD). This study employed metataxonomic approach in order investigate if V. affects gut microbiota (bacteria and fungi) of adult A. mellifera honey well bee bread (BB) stored colonies demonstrating sever...

Pattern recognition receptors (PRRs) belonging to the multigene family of receptor-like kinases (RLKs) are the sensing devices of plants for microbe- or pathogen-associated molecular patterns released from microbial organisms. Here we describe Rnr8 (for Required for non-host resistance 8) encoding HvLEMK1, a LRR-malectin domain-containing transmembrane RLK that mediates non-host resistance of b...

We analyzed the pathogenesis-related generation of H2O2 using the microscopic detection of 3,3-diaminobenzidine polymerization in near-isogenic barley (Hordeum vulgare L.) lines carrying different powdery mildew (Blumeria graminis f.sp. hordei) resistance genes, and in a line expressing chemically activated resistance after treatment with 2,6-dichloroisonicotinic acid (DCINA). Hypersensitive ce...
