Abstract excerpt

Arabidopsis phytochrome A (phyA) regulates not only seed germination and seedling de-etiolation but also circadian rhythms and flowering time in adult plants. The SUPPRESSOR OF PHYA-105 (SPA1) acts as a negative regulator of phyA-mediated de-etiolation of young seedlings, but its roles in adult plants have not yet been described. Here, we show that SPA1 is involved in regulating circadian rhythms and flowering...
