Interchromosomal Transfer of Immune Regulation During Infection of Barley with the Powdery Mildew Pathogen
Powdery mildew pathogens colonize over 9500 plant species, causing critical yield loss. The Ascomycete fungus, Blumeria graminis f. sp. hordei (Bgh), causes powdery mildew disease in barley (Hordeum vulgare L.). Successful infection begins with penetration of host epidermal cells, culminating in haustorial feeding structures, facilitating delivery of fungal effectors to the plant and exchange o...
متن کاملAllelic barley MLA immune receptors recognize sequence-unrelated avirulence effectors of the powdery mildew pathogen.
Disease-resistance genes encoding intracellular nucleotide-binding domain and leucine-rich repeat proteins (NLRs) are key components of the plant innate immune system and typically detect the presence of isolate-specific avirulence (AVR) effectors from pathogens. NLR genes define the fastest-evolving gene family of flowering plants and are often arranged in gene clusters containing multiple par...
متن کاملInduction of Disease Symptoms in Barley by Powdery Mildew.
Powdery millews usually grow superficially on their hosts but produce symptoms of disease throughout the underlying host tissues. The symptoms include marked increase in respiratory rate (1, 3, 15. 24, 26, 30. 35); accumulation of organic and inorganic substances (1,29, 36): increase in dry weight (10. 26) ; increase in wet weight (3) decrease in photosynthesis when the disease is well develope...
متن کاملHost-induced gene silencing in barley powdery mildew reveals a class of ribonuclease-like effectors.
Obligate biotrophic pathogens of plants must circumvent or counteract defenses to guarantee accommodation inside the host. To do so, they secrete a variety of effectors that regulate host immunity and facilitate the establishment of pathogen feeding structures called haustoria. The barley powdery mildew fungus Blumeria graminis f. sp. hordei produces a large number of proteins predicted to be s...
متن کاملAntagonistic control of powdery mildew host cell entry by barley calcium-dependent protein kinases (CDPKs).
Calcium-dependent protein kinases (CDPKs) are known to play pivotal roles in intracellular signaling during abiotic and biotic stress responses. To unravel potential functions of CDPKs in the course of barley (Hordeum vulgare)-powdery mildew (Blumeria graminis) interactions, we systematically analyzed the HvCDPK gene family. We found that, according to the existence of respective expressed sequ...
