A 51-kD MAPK is activated during incompatible and compatible P. infestans-potato interactions in potato leaves. A 51-kD MAPK activity, which was identified as StMPK1 (AB062138), was indicated by in-gel kinase assay using MBP as a substrate. The same samples were stained with Coomassie Brilliant Blue, and the bands corresponding to ribulose-1,5-bisphosphate carboxylase large subunit (RBCL) are shown.
