There was a mistake in Figure 1 as published. Some chemical formulas were not correct. The corrected Figure 1 appears below.
Figure 1.
Possible biosynthesis routes for SA in plants. Full lines are conversion steps, dotted lines are transport from chloroplast to cytosol, the dashed line is an alternative, unknown biosynthesis route. The question mark indicates an unidentified protein. It is unclear whether the steps leading up to phenylalanine are performed in the chloroplast or cytosol, or in both simultaneously, as there are chloroplastic and cytosolic CMs. Proteins are indicated in blue and are abbreviated as follows: the enzymes ICS, isochorismate synthase; CM, chorismate mutase; PAL, phenylalanine ammonia-lyase; AIM1,abnormal inflorescence meristem1; BA2H, benzoic acid 2-hydroxylase; PBS3, avrPphB SUSCEPTIBLE3; EPS1, ENHANCED PSEUDOMONAS SUSCEPTIBILITY 1 and the transporter EDS5, ENHANCED DISEASE SUSCEPTIBILITY 5. In Arabidopsis, sid1 mutants are loss-of-function eds5 mutants, while sid2 mutants are loss-of-function ics1 mutants.
