Change in transcriptome associated with the transition to reproductive stage . (A) Expression pattern of 29,119 genes from 20 to 76 DAT based on relative expression values indicate drastic change between 41-48 DAT. Blue, yellow, and red lines indicate high, middle, and low expression values, respectively, at 20 DAT. (B) Expression pattern of rice florigen genes, Hd3a (blue) and RFT1 (red), from 20 to 76 DAT. Error bars indicate s.e.m. (n = 3). (C) Expression pattern of seven miR169 precursors from 20 to 76 DAT. Each miRNA precursor was represented in the microarray as two probes corresponding to the 3' and 5' sequence, respectively. Error bars indicate s.e.m. (n = 3). (D) GO analysis of the 357 genes upregulated from 41 to 48 DAT. The colored circles represent enriched categories based on the p-values corrected for multiple testing (FDR) ranging from 0.05 (yellow) or below (orange). The size of the circle is proportional to the number of genes annotated to that node. (E) Expression pattern of five miR399 precursors from 20 to 76 DAT. Error bars indicate s.e.m. (n = 3).
