Induction 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 کاملInterchromosomal 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 کاملVirus-induced gene silencing-based functional characterization of genes associated with powdery mildew resistance in barley.
We successfully implemented virus-induced gene silencing (VIGS) in barley (Hordeum vulgare) for the functional characterization of genes required for Mla13-mediated resistance toward the biotrophic barley pathogen Blumeria graminis f. sp. hordei. Initially, barley cultivars were screened for their ability to host the barley stripe mosaic virus (BSMV)-VIGS vector by allowing its replication and ...
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 کاملMethyl jasmonate alters polyamine metabolism and induces systemic protection against powdery mildew infection in barley seedlings.
Treatment of the first leaves of barley (Hordeum vulgare L. cv. Golden Promise) seedlings with methyl jasmonate (MJ) led to small, but significant increases in levels of free putrescine and spermine 1 d later and to significant increases in levels of free putrescine, spermidine and spermine by 4 d following treatment. MJ-treated first leaves also exhibited significant increases in the amounts o...
