<i>OsbHLH174</i> overexpression transgenic plants showed an increase in the leaf angle.

<p>(A) The morphology of wild type (WT) and <i>OsbHLH174</i>: OX plants, at the seedling, tillering and heading stages. (B) quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) analysis of <i>OsbHLH174</i> transcripts in WT and <i>OsbHLH174</i>: OX at the seedling stage. (C) FLA and TSLA of the wild type and <i>OsbHLH174</i>:OX-1 and -2 at the heading stage (<i>P</i>< 0.001, n≥ 5).
