Branching in Wild-Type and rax1-2 Plants

	Ws-2 (n)	rax1-2 (n)
Rosette branches with IM (LD)	4.1 ± 0.15 (24)	2.4 ± 0.17* (24)
Cauline branches with IM (LD)	2.8 ± 0.10 (24)	2.9 ± 0.10 (24)
Rosette branches with IM (SD)	6.1 ± 0.20 (43)	3.1 ± 0.27* (63)
Cauline branches with IM (SD)	7.3 ± 0.13 (43)	4.0 ± 0.18* (63)
Rosette branches with IM after decapitation (SD)	6.7 ± 0.33 (15)	3.1 ± 0.27* (18)

Plants were grown in the photoperiodic conditions indicated. Rosette branches originate from axils on the unexpanded stem, while cauline branches originated from the expanded segment of the stem. Only branches topped by inflorescence meristems (IM) were observed. Errors are standard errors of the mean, and the asterisks indicate significant differences (P < 0.01) identified with Student's t test. Numbers in parentheses indicate the number of individuals tested.
