Infiltration of leaves\u00a0with various herbicides, targetting photosynthetic electron transport, were utilized to mimic changes in redox state (otherwise caused by changes in light irradiance)\u00a0of photosynthetic electron transport components and study the response of APX2.\u00a0This was successfully\u00a0 utilized in the following publication:\u00a0Jung, H., Crisp, P.A., Estavillo, G.M., Cole, B., Hong, F., Mockler, T.C., Pogson, B.J., and Chory, J. (2013). Subset of heat-shock transcription factors required for the early response of Arabidopsis to excess light. Proc. Natl. Acad. Sci. 110: 14474\u201314479.
