The Arabidopsis blue-light photoreceptor CRY2 is active in darkness to inhibit root growth
{{output}}
Cryptochromes (CRYs) are blue-light receptors that regulate diverse aspects of plant growth. However, whether and how non-photoexcited CRYs function in darkness or non-blue-light conditions is unknown. Here, we show that CRY2 affects the Arabidopsis transcript... ...
