Blue light regulates many physiological and developmental processes in higher plants through the action of multiple photosensory systems. The analysis of photomorphogenic mutants is leading to a better understanding of how the different photosensory systems mediate the wide range of responses observed in blue light. A review of the current literature on photomorphogenic mutants makes it apparent that redundancies exist in photoreceptor function. For example, many blue‐light responses that have been shown to be regulated by a blue‐light photosensory system are also under phytochrome control. The study of various light‐response mutants suggests that a complex sensory network regulates light‐mediated responses. This article attempts to piece together information regarding the sensory systems responsible for blue‐light‐regulated responses.
