A Novel Molecular Solution for Ultraviolet Light Detection in Caenorhabditis elegans

The Relationship of Light Dose to Locomotion Rate at Various Wavelengths
(A) Mean locomotion rate of the unc-31(e928) mutant at various powers and wavelengths of light. The highest power for each color is close to the maximum power of that color that we can project onto the culture plate. The maximum power of green light causes only a weak response. The inset expands the low power region of the graph and shows the strong response to UV light at a power where blue and blue-violet light cause only weak responses. Error bars in (A) and (B) are the standard errors in populations of ten animals.
(B) Response of N2 (wild type) to various powers and wavelengths of light. A dashed line indicates N2′s basal rate in low power white light (70 nW/mm2). Note that low power UV light causes a response greater than a 7-fold higher power of blue or blue-violet light. Note that green light does not cause a significant locomotion response, even at the highest power.
