tgaII Mutant Lines Are Sensitive to Excessive Light and Unresponsive to β-cc.

(A) Leaf bleaching (top panel) and lipid peroxidation, monitored by autoluminescence imaging (bottom panel), of wild-type and oftgaII mutant plants pretreated with β-cc or with water. The color palette shows signal intensity from low (dark blue) to high (white) values.

(B) HPLC-UV quantification of the HOTE normalized on wild-type control (CTRL). The black diamonds indicate significant differences with P < 0.05. Error bars = +sd between the four biological replicates from leaves of three plants per genotype per treatment. Two full experimental replicates.
