Diurnal expression patterns of GmLHY1a/1b/2a/2b in WT plants and T2 homozygous quadruple mutants of GmLHY. a–d qRT-PCR analysis of GmLHY2b, GmLHY2a, GmLHY1a, and GmLHY1b expression levels in the leaves at 20 DAE under 16 h light/8 h dark (long day; LD) conditions, respectively. Data shown are relative to the control gene GmTUB and represent means ± standard error of the mean (s.e.m.) for three biological replicates. Bars indicate the s.e.m. Black and white bars represent dark and light periods, respectively
