Read Statistics

RNA was isolated and sequenced from a root tissues. Abiotic stress assays (heat, cold, drought) were conducted on seedlings. Over 7 million reads (1.9Gb) of sequence were acquired. Raw data has been uploaded to the NCBI Short Read Archive. An additional 4 MiSeq libraries (HLC0, HL80, HL125, HL225) were not used in the assembly but were used in expression analysis.
