lite-1(xu7) X. Show Description
Defective phototaxis (light avoidance). To identify lite-1(xu7) homozygotes, place day 1 adults on a freshly seeded NGM plate with a thin lawn of OP50. Deliver 2 second pulses of short wavelength light (UV, purple, blue) from an arc lamp to the head of a worm that is slowly moving forward through a 5-10x objective lens in conjunction with a room lens under a fluorescent dissection scope. Manually move the plate so only the anterior of the worm appears in the field of view. Wild-type worms respond by initiating reversals while homozygous mutants do not. Maintain under normal conditions. Reference: Liu J, et al (2010) Nature Neurosci 13:715-22.
