Expression analysis of OsMYB103L. (A) Expression of OsMYB103L in various organs determined by qRT-PCR analysis. Roots were harvested from 2-week-old plants. Culms, leaf blades and mature panicles were harvested from rice plants at heading stage. Young panicles were collected at the 5 cm stage. Rice ACTIN1 gene was used as internal control. Error bars represent the SD of transcript levels determined from three independent replicates. (B) to (I) Examination of GUS activity in the transgenic plants expressing OsMYB103L pro::GUS. The GUS activity is shown in coleoptiles (B), root (C), culm (D), leaf (E), young panicle (F) and mature panicle (G-I). GUS activity was also detected in pedicel, lemma and palea in mature panicle (H), while no GUS activity in sterile lemma, lodicule, pistil and stamen (I).
