Accumulation of OsAGPL3 mRNA in response to ABA Pre-cultured cells were transfer to the medium supplemented with various concentrations of ABA as indicated. After 24 h of cultured in the dark, suspension cells were collected and total RNAs were isolated. OsAGPL3 (accession no. AK100910) mRNA levels were measured by northern blot analysis.

Primer combinations for restriction endonucleases AvaII and TaqI are shown at the top of the cDNA-AFLP autoradiogram. (B) Classification of TDFs by their induction patterns. Total 11099 TDFs were identified. In total, 9799 TDFs were not different between each samples. 63, 321, 66 and 94 TDFs were increased in the cultured cells grown in the +S+ABA, + ABA, +S and +S+ABA medium, respectively.
