Exploring drought-associated genes of Thellungiella grown at the field site and in the growth cabinet. A) Relationships between genes differentially expressed in Thellungiella at the Yukon field site and plants drought-stressed in cabinets compared to cabinet controls are presented in Venn diagram form. The numbers of genes indicated in blue text are down-regulated relative to cabinet controls and the numbers of genes presented in red text are up-regulated relative to cabinet controls. Black text represents the number of genes regulated in opposite directions in 2003 compared to 2005. B) Summary list of candidate drought-responsive genes in Thellungiella. 20 genes (shaded region in panel A) showed differential expression in 2003 and in cabinet-grown plants subjected to simulated drought stress compared to cabinet controls. A subset of 13 genes whose expression was not influenced by either salt or cold exposure is presented [28–39].
