GmFLD, a soybean homolog of the autonomous pathway gene FLOWERING LOCUS D, promotes flowering in Arabidopsis thaliana

Table 1 Flowering time of T1 transgenic A. thaliana plants of GmFLD and GmLDL2

Genotype	Days to visible buds	Days to flower opening	Rosette leaf number	Cauline leaf number	N
Col	28.7 ± 1.8	34.3 ± 1.8	12.3 ± 1.3	3.2 ± 0.7	15
GmFLD/Col	24.8 ± 2.1	31.6 ± 2.0	9.4 ± 1.4	2.3 ± 0.5	16
GmLDL2/Col	28.1 ± 1.7	34.1 ± 2.0	12.8 ± 0.9	2.8 ± 0.7	16
fld	86.5 ± 3.4	95 ± 3.4	59.7 ± 2.5	7.9 ± 1.4	13
GmFLD/fld	34.4 ± 8.2	42.8 ± 8.8	10.6 ± 2.5	3.4 ± 1.0	19*

The values are the mean ± SD. N, number of plants scored for phenotype.
*Totally 27 T1 plants were obtained and the flowering time of 19 early-flowering plants was examined. The other eight plants flowered almost as late as the fld mutants were not included in this table because no GmFLD expression could be detected in these transgenic plants.
