a
Number of juvenile leaves determined by identifying the last leaf that had trichomes only on the adaxial side. (ND) not determined.
b
The cauline leaves produced in plants marked with an asterisk subtend ectopic flowers instead of secondary shoots.
c
In experiment 1, plants were grown under long days (16 h light/8 h dark).
d
The genotype of Columbia is fri FLC.
e
Homozygous agl20-101D FRI FLC.
f
Heterozygous agl20-101D/+ FRI FLC.
g
In experiment 2, plants were grown under long days (LD) and short days (SD; 10 h light/14 h dark cycle).
