Differential expression level of the PTB1 gene between the transgenic line M-fs4B and ptb1 mutant. The relative expression level of the PTB1 gene was determined using q-PCR analysis with RNA isolated from the pistil of the transgenic line M-fs4B and ptb1 mutant. Relative expression levels were measured as the mean ± s.e.m. (n = 3). All P values are based on two-tailed t-tests
