Fig. 6.

Expression levels of WUS and CLV3 with/without cytokinin treatment. Aerial parts of 10-day-old seedlings grown on normal or cytokinin-containing media were analyzed by qRT-PCR. The expression levels were normalized with respect to that of β-TUBULIN and the normalized values without cytokinin treatment were set at 1. Data shown are means of four independent samples (10 individuals were collected as a pool for each sample) with error bars representing the SD. Asterisks indicate significant differences by Student’s t-test (P < 0.05).
