Arabidopsis NF-YC7 Interacts with CRY2 and PIF4/5 to Repress Blue Light-Inhibited Hypocotyl Elongation.

ABSTRACT: Light is an important environmental factor. Plants adapt to their light environment by developing the optimal phenotypes. Light-mediated hypocotyl growth is an ideal phenotype for studying how plants respond to light. Thus far, many signaling components in light-mediated hypocotyl growth have been reported. Here, we focused on identifying the transcription factors (TFs) involved in blue light-mediated hypocotyl growth. We analyzed the blue-light-mediated hypocotyl lengths of Arabidopsis TF-overexpressing lines and identified three NF-YC proteins, NF-YC7, NF-YC5, and NF-YC8 (NF-YCs being the short name), as the negative regulators in blue light-inhibited hypocotyl elongation. NF-YC-overexpressing lines developed longer hypocotyls than those of the wild type under blue light, while the defic
