OsSPL4 regulates spikelet hull development by affecting cell proliferation A, B Scanning electron microscope images of the outer glume (middle), A Control plants; B spl4-d3 lines, scale bar = 100 μm. C, D Comparisons of cell length and cell number in the longitudinal direction of the spikelet between the control and spl4-d3 plants (n = 10 spikelets). C Cell length. D Cell number. E KEGG pathway of the DEGs identified in young panicles of the control and spl4-d3 transgenic plants. RichFactor is the ratio of DEG number and background gene number. F Heatmap showing the expression levels of genes related to floral organ identify in our RNA-seq between the spl4-d3 lines and control plants. Fold change of the FPKM values (spl4-d3/control) were used. G Comparisons of the expression levels of cell-cycle genes in young panicles of the control and spl4-d3 plants using qRT-PCR. The data are presented as mean ± SD (n = 3). Significant difference was determined by Student’s t test, * P < 0.05, ** P < 0.01
