Plant development is profoundly regulated by ambient light cues through the red/far-red photoreceptors, the phytochromes. Early phytochrome signaling events include the translocation of phytochromes from the cytoplasm to subnuclear domains called photobodies and the degradation of antagonistically acting phytochrome-interacting factors (PIFs). We recently identified a key phytochrome signaling component, HEMERA (HMR), that is essential for both phytochrome B (phyB) localization to photobodies… CONTINUE READING
