AKIN10 overexpression delays flowering. Plants were grown in soil under LDs for 6 weeks before taking photographs (A). Flowering times were measured by counting the days to bolting and rosette leaf numbers at bolting (B, left and right panels, respectively). Transgenic plants overexpressing IDD8 (8-ox1 and 8-ox2), AKIN10 (10-ox), and AKIN11 (11-ox) and their gene knockout mutants were analyzed. The countings of approximately 20 plants were averaged and statistically analyzed using Student t-test (*P < 0.01, difference from col-0). Bars indicate standard error of the mean.
