e0“slight increases in expression of two antioxidant genes, a glutathione S transferase and an ascorbate peroxidase occurred in association with enhanced cell/tissue death and H2O2 accumulation.”
t0“mlo5, a resistance gene effective against a biotrophic pathogen (Blumeria graminis fsp. hordei) confers enhanced susceptibility of barley to the necrotrophic fungus Bipolaris sorokiniana (teleomorph: Cochliobolus sativus)”

Other claims from this paper (9)
- Observation Barley mlo5 confers race non-specific resistance to Blumeria graminis f.sp. hordei.
- Observation Barley lines containing mlo5 show enhanced susceptibility to Bipolaris sorokiniana.
- Observation Barley lines containing mlo5 show enhanced susceptibility to the fungal toxic culture filtrate.
- Association Enhanced necrotic symptoms were linked to greater hydrogen peroxide accumulation.
- Association PR1- b transcript accumulation increased alongside cell death and hydrogen peroxide accumulation.
- Association Expression of ascorbate peroxidase increased slightly in association with cell death and hydrogen peroxide accumulation.
- Mechanism The authors hypothesize that the barley Mlo product negatively regulates cell death.
- Mechanism The authors conclude that compromised Mlo control is effective against the biotrophic powdery mildew pathogen.
- Mechanism The authors conclude that compromised Mlo does not control B. sorokiniana.
