Transcription profiling of Arabidopsis seedlings supplemented with sucrose, mannitol or atrazine to assess temporal effects of sucrose on atrazine tolerance

ABSTRACT: Seeds of Arabidopsis thaliana (ecotype Columbia) were surface-sterilized inbayrochlore/ethanol (1:1, v/v), rinsed in absolute ethanol and dried overnight. Germination and growth were carried out under axenic conditions in square Petri dishes. After seeds were sowed, Petri dishes were placed at 4°C for 48 h in order to break dormancy and homogenize germination, and then transferred to a control growth chamber at 22°C under a 16-h light period regime at 4500 lux for 4 weeks. Growth medium consisted of 0.8% (w/v) agar in 1x Murashige and Skoog (MS) basal salt mix (Sigma, St. Louis, MO, USA) adjusted to pH 5.7. After 4 weeks of cultivation on vertical plates plantlets were transferred on fresh medium complemented with atrazine 10 µM and with sucrose 80mM or mannitol 80 mM which were directly added during preparation of agar-MS media prior to sterilisation. Atrazine was sterilized by microfiltration through 0.2 µm cellulose acetate filters (Polylabo, Strasbourg, France) and then axenically added to melted agar-MS medium prior to pouring into Petri dishes. Then plantlets were harvested after 12, 24 and 48 hours of transfer and extracted for RNA. Plantlets grown on MS medium were harvested and extracted for RNA as control.
