Temporal gene expression patterns of rice panicle development-related genes in SAM regions during early stages of panicle development. Levels of mRNA accumulation were examined by quantitative RT–PCR. Timing of transition was determined by the microscopic observation of SAM parts of test samples for all sampling dates. Day 2 indicates the timing of the start of primary rachis differentiation. The results are the mean ± SE (n = 3 individual plants). Three RT–PCRs were done for each cDNA sample from one plant. mRNAs were prepared from the corresponding SAM samples grown under SD conditions. Similar data were obtained when normalized by number of SAMs for mRNA preparation.
