Table S1 The quantitative trait loci (QTLs)/genes to control grain size and grain filling.
Table S2 Predicted transcript factors binding to the promoter of OsYUC11.
Figure S1 Transcriptome comparison between developing grains of the wild type (WYJ8 ) and RGB1 RNA-interfered transgenic line (RGB1Ri-5 ) using RNA-SEQ. (a) Numbers of genes up- and down-regulated in the comparisons between WYJ8 andRGB1Ri-5 at 5 and 10 day after flowering (DAF). (b) The top 5 enriched KEGG pathways in grains.
Figure S2 Heat maps of differentially expressed genes (DGEs) involved in auxin transport (a) , auxin biosynthesis(b) and auxin signaling (c) . The maps were plotted using the value of RPKM for each gene in the different samples: blue indicates low values, red indicates high values. The indicated scale is the log2 value of the normalized level of gene expression.
Figure S3 Expressions of OsTAR1 and OsYUC9 in WYJ8 and RGB1Ri lines during filling stage (a), and its relation to auxin content of grains (b).
