Abstract
Circadian clocks are endogenous timing mechanisms that allow an organism to adapt cellular processes in anticipation of predictable changes in the environment. Luciferase reporters are well utilized as an effective, nondestructive method to measure circadian rhythms of promoter activity in Arabidopsis. Obtaining stable transgenic reporter lines can be laborious. Here, we report a protocol for Agrobacterium-mediated seedling transformation tailored for plant circadian studies. We show that period estimates generated from wild-type and clock-mutant seedlings transformed with circadian luciferase reporters are similar to rhythms obtained from equivalent stable transgenic seedlings. These experiments demonstrate the versatility and robustness of the protocol for testing new constructs or quickly assessing circadian effects in any genotype of interest.
