Effects of ein2 on SA Concentrations in the cpr ein2 and cpr npr1 ein2 Mutants.

Leaves from 4-week-old, soil-grown plants were collected and analyzed by HPLC for free SA. The SA value in c5n1e2 (which is off the scale of the graph) is printed next to the bar to allow a better comparison between samples. The values are an average of two replicates ± range. +avr, plants infected with P. s. maculicola ES4326/avrRpt2 at 3 days before tissue harvest; c5n1, cpr5 npr1; c5e2, cpr5 ein2; c5n1e2, cpr5 npr1 ein2; c6n1, cpr6 npr1; c6e2, cpr6 ein2; c6n1e2, cpr6 npr1 ein2; FW, fresh weight; WT, wild-type BGL2-GUS transgenic line.
