Cloning analysis of the OsPG1. a Fine mapping of OsPG1. b Gene structure and the mutation of genome and cDNA in OsPG1. The red arrow indicates the mutant site and the red dotted line indicates the incorrected splicing sequences. c Protein sequence alignment of OsPG1 and ospg1. d Expression analysis of OsPG1 in WT and ltn-212 leaves (n = 3). e Expression analysis of OsPG1 in WT leaf bottom, middle and tip (n = 3). Data are means ± SD. ** indicates significance at P ≤ 0.01 and * indicates significance at P ≤ 0.05. a, b, c indicates significance at P ≤ 0.01 (Student’s t test)
