Cryptochromes and phytochromes are the major photosensory receptors in plants and often regulate similar photomorphogenic responses. The molecular mechanisms underlying functional interactions of cryptochromes and phytochromes remain largely unclear. We h

The shift in plants from vegetative growth to floral development is regulated by red-far-red light receptors (phytochromes) and blue–ultraviolet A light receptors (cryptochromes). A mutation in the Arabidopsis thaliana CRY2 gene encoding a blue-light rece

During the past decade, molecular genetic studies on the reference plant Arabidopsis have established a largely linear signal transduction pathway for the response to ethylene gas. The biochemical modes of action of many of the signaling components are st

Plants use ethylene gas as a signal to regulate myriad transdevelopmental processes and stress responses. The Arabidopsis EIN3 protein is a key transcription factor remediating ethylene-regulated gene expression and hismorphological responses. Here, we re
