Changes in the Arabidopsis thaliana apex at floral transition
Jacqmard et al. (pp. 571-576) analyse rate of cell division and morphology in the shoot apical meristem (SAM) of 2-month-old arabidopsis plants before and after induction of flowering by 1 long day (LD). Mitotic activity is shown to increase 24 h after the start of the LD and is followed by SAM enlargement and doming after 44 and 48 h, respectively.
