Fiegen, M.; Knogge, W.;Amino acid alterations in isoforms of the effector protein NIP1 from Rhynchosporium secalis have similar effects on its avirulence- and virulence-associated activities on barleyPhysiol. Mol. Plant Pathol.61299-302(2002)DOI: 10.1006/pmpp.2002.0442
The secreted effector protein NIP1 from the barley pathogen Rhynchosporium secalis is a specific elicitor of defense reactions in host plants carrying the resistance gene Rrs1. In addition, it has activities associated with fungal virulence; independent of the plant genotype it stimulates the plant plasma membrane H+-ATPase and induces leaf necrosis. Four NIP1 isoforms differing in single amino acid residues were isolated from various naturally occurring fungal strains. All three activities of the protein (race specificity, H+-ATPase stimulation, necrosis induction) were affected by the amino acid alterations in a similar way suggesting that they are mediated through a single plant receptor.
