About The Cover

Cover image expansion

COVER The Chinese character for "light" on an Arabidopsis leaf. This image was created by exploiting the plant chloroplasts' protective response to strong light. Upon selective irradiation of the area within the character, chloroplasts in this region move from the cell surface to the side walls when light is detected by the blue light receptor NPL1. The leaf surface then appears paler in color in the irradiated area. See page 2138 [Image: M. Wada]
