Current Biology: Ancient functional divergence of secreted proteases in tomato

Thu August 20th, 2015

Renier van der Hoorn and his team members show that two secreted proteases of tomato, Rcr3 and Pip1, are paralogous proteases that differ in their expression levels and exposed surface and diverged >36 mya. Pip1 is an important immune protease acting against unrelated apoplastic pathogens, while Rcr3 is a co-receptor for pathogen-derived inhibitors, playing a minor role in the absence of immune receptor Cf-2.
