Hajouj, T., Michelis, R., and Gepstein, S. Cloning and Characterization of a Receptor-Like Protein Kinase Gene Associated with Senescence.
On page 1311, the Pto gene is not correctly described. The related paragraph is correctly printed below.
One of the known defense-related genes is the Pto, Ser/Thr protein kinase receptor. Because SARK and Pto encode protein kinases, the two genes may be compared. The Pto contains neither the membrane-spanning domain nor the LRR motif and appears to function as an intracellular receptor for the signal molecule (Sessa et al., 1998). It is apparent that the structural differences rule out the possibility of SARK mediating the senescence program through the Pto defense-related genetic pathway.
