The Resilience of Young Leaves to Excessive Light Depends on SCL14.

(A) Leaf bleaching (on the left) and lipid peroxidation monitored by autoluminescence imaging (on the right) of wild-type, scl14, and OE:SCL14 detached leaves after high-light stress.

(B) Maximum quantum yield of PSII photochemistry determined by the Fv/Fm chlorophyll fluorescence ratio of wild-type, scl14, and OE:SCL14 mature and young detached leaves after high-light stress.

(C) HPLC-UV quantification of the HOTE normalized to wild-type mature leaves. Black diamonds indicate significant differences (P < 0.05). Error bars = +sd between the three biological replicates of pools of four mature leaves or 10 young leaves. Two full experimental replicates.
