Independent regulation of flowering by phytochrome B and gibberellins in Arabidopsis.

Plant physiology - 1 Aug 1999

Blázquez M A, Weigel D

Abstract excerpt

Phytochromes and gibberellins (GAs) coordinately regulate multiple aspects of Arabidopsis development. Phytochrome B (PHYB) promotes seed germination by increasing GA biosynthesis, but inhibits hypocotyl elongation by decreasing the responsiveness to GAs. Later in the life cycle of the plant, PHYB and GAs have opposite effects on flowering. PHYB delays flowering, while GAs promote flowering, particularly under...
