MPSS data were obtained from the following samples: young leaves, young roots, young leaves - cold stressed, young roots - cold stressed, young leaves - drought stressed, young roots - drought stressed, young leaves - salt stressed, young roots - salt stressed, mature leaves, mature roots, 10 day old seedlings (dark grown), 3 day old seedlings, immature panicle, meristematic tissue, ovary & mature stigma, pollen, callus.
Data processing
For each of these samples, we determined the normalized abundance value for each signature in the library in "transcripts per million" or TPM. More details on this process are available in Meyers et al. (2004, Genome Research 14:1641). The numbers in the VALUE column represent the average expression level of the corresponding signatures for the libraries described above. More details about the samples, library replicates and individual signatures are available at http://mpss.udel.edu/rice.
