CO-Independent miR172 Function in Photoperiodic Flowering.

(A) Measurements of flowering times in 35S∷172 co plants. Plants grown for 30 d were measured and averaged. Values in the table are means ± se.

(B) FT expression in 35S∷172 co plants grown under either LDs or SDs. Transcript levels were examined by RT-PCR, and miR172 abundance was examined by RNA gel blot hybridization.

(C) A schematic working model for miR172 function in photoperiodic flowering. miR172 mediates light signals from GI and promotes flowering by inducing FT independent of CO.
