Puccinia hordei

Puccinia hordei is a species of rust fungus. A plant pathogen, it can cause leaf rust of barley, also known as brown rust of barley.^[3][4] It was originally found on the dry leaves of Hordeum vulgare in Germany.^[5]

Host resistance

At the time of Johnston et al., 2013's discovery of severe susceptibility in Golden Promise, this was considered to be the most susceptible variety in the world.^[4] Soon thereafter however, Yeo et al., 2014 found SusPtrit was slightly worse.^[4] These results alter the meaning of such a basic term as "fully susceptible" to brown rust.^[4]

In 2007 several resistance genes for this pathogen including receptor-like kinase (RLK), WIR1, WIR1 homologues, peroxidases, superoxide dismutase and thaumatin were found in barley.^[6][7][8]
