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]
