RNA sequencing from micro-dissected meristems of the main shoot of the following mutant lines: the triple mutant puchi-1 x bop1-4 x bop2-11 (PB); the single mutant lfy-12 (L-12), and the single mutant jagged-5D (J5D) at early floral stage (floral transition occured but meristems were sampled before the plants had bolted). These three mutants are in a Col-0 genetic background. Three independant replicates (1, 2, 3) per genotype are provided, each replicate is a pool of ~10 apices. Plants were cultured in classical Arabidopsis growth conditions in culture chambers, starting with 21 days in short days before switching to long-day conditions untill dissection and sampling (See Dieudonné S. et al. for details). cDNA was sequenced using NextSeq500 from Illumina. After classical read quality filtering, each sample yielded on average 43 million sequences.
