Figure 2From: Use of a highly sensitive two-dimensional luminescence imaging system to monitor endogenous bioluminescence in plant leavesDelayed chlorophyll fluorescence images. Luminescence from leaves of Arabidopsis (A) and Tradescantia (B). Images are 5-minute exposures taken as soon as possible after transfer of leaves to the equipment. A conventional photograph of the Tradescantia leaf imaged in (B) is shown to illustrate the pattern of variegation (C).Back to article page
