Plants experience sudden increase in salinity after transplantation into salt contaminate field.The salt responsive transcriptome of a relatively salt tolerant Brassica napus line,N119,identified in our previous study was dissected for a better understanding of the regulatory network in response to sudden increase of salinity.Both the root and leaf transcriptome at 1 h and 12 h post-stress were sequenced.De novo assembly followed by sequence clustering yielded 161,537 non-redundant sequences.
