Plants have evolved a range of sophisticated mechanisms to adapt and respond to their
natural habitat. For example, plants rely heavily upon the surrounding light environment to
direct their growth and development. Several different photoreceptor families are known to
mediate the effects of light on plant development (1–3). These include the phytochrome
(phy) family of photoreceptors, which monitor the red (600–700 nm) and far-red (700–750
nm) regions of the solar spectrum (4). In addition to the phytochromes, many important …
