Early-flowering phenotype of aln and aah mutants. WT, aln-1, aln-2, and aah seeds were sown on soil and grown under long-day conditions. a Growth of representative plants for each genotype at 4 WAG. b Number of rosette leaves when the primary inflorescence stems were about 1 cm long (n ≥ 32). c Fresh weight (FW) of rosette leaves, petioles, stems, cauline leaves, and siliques from plants at 5 WAG (n ≥ 9). d Growth of representative plants for each genotype at 5 WAG. Bar = 5 cm. A linear model with the genotype as a factor was fitted to the data. Asterisks denote significant differences from WT (*P < 0.05, **P < 0.01, ***P < 0.001, two-tailed t-tests based on the model)
