Light Responsiveness and Regulatory Role of miR319 in TCP Levels in Photomorphogenic Arabidopsis.

(A) 5′-RACE analysis of the cleavage site of TCP24 mRNA within the TCP24-miR319c duplex.

(B) The light responsiveness of miR319 members.

(C) qRT-PCR analysis of the mRNA level of TCP genes. The expression of each gene under W light at times indicated was normalized to that of UBQ10 and was relative to that of etiolated seedlings (0 h). Data are mean ± se from two biological replicates (each with two technical replicates).

(D) The hypocotyl lengths of different allelic jaw-D mutant seedlings under Wc of the indicated fluence rates normalized to the length under the dark. Data are mean ± se. * and **, significantly different from wild-type Arabidopsis (Col-0) (P < 0.05 and P < 0.01, Student’s t test; n = 24 to 27).
