(Submitter supplied) Arabidopsis thaliana and Eutrema salsugineum show the ability to cold acclimate. However, the degree of freezing tolerance depends in both cases on the accession. To elucidate the transcriptional basis of this differencial freezing tolerance, we performed where we grew plants under control conditions (20°C/18°C day/night) or under cold conditions (additional 4°C for 2 weeks). Rosettes were harvested from non-acclimated and cold acclimated plants for RNA isolation. more...

(Submitter supplied) Arabidopsis thaliana is a glycophyte with a low salt tolerance, while Eutrema is a halophyte with a very high salt tolerance. To elucidate the transcriptional basis of this difference, we performed hydroponis culture experiments where we grew plants under control conditions (25 mM NaCl) or under salt stress (200 mM NaCl for both species, 500 mM for Eutrema). Salt concentration was increased for the stress treatments by increments of 50 mM per day (25 mM on the first day). more...

(Submitter supplied) Arabidopsis thaliana is not particularly stress tolerant and may lack protective mechanisms required to survive extreme environmental conditions. Thellungiella salsuginea has therefore attracted increasing interest as an alternative plant model species that possesses high tolerance of various abiotic stresses. While the T. salsuginea genome has recently been sequenced, its annotation is still far from complete and, due to the low number of ESTs available, evidence for actual transcriptional activity is lacking for most genes. more...
