(Submitter supplied) Cell-type specific transcriptional profiles were generated by FACS (Fluorescence Activated Cell Sorting) sorting of roots that express cell-type specific GFP-reporters. Four different GFP-reporter lines were utilized allowing us to obtain transcriptional profiles for cells in major radial zones of the root. FACS cell populations were isolated from roots grown under standard conditions or roots that had been transfered to media supplemented with 140 mM NaCl for 1 hour, 3 hours, 8 hours, 20 hours, 32 hours and 48 hours. more...

(Submitter supplied) A genome-scale test of dynamic gene expression changes and homeostasis in salt stress response was genereated using whole roots sample of wild type columbia. Seedlings of columbia were grown under standard conditions for 5 days, and then they were transfered to media supplemented with 140mM NaCl for a series of time: 1 hour, 3 hours, 20 hours, 2 days, 4 days and and 8 days, as well as to standard condition for the same series of time. more...

(Submitter supplied) In order to study the improtance of HSFA6b in salt and heat stresses of arabidopsis, we generated the HSFA6b-overexpression (HSFA6b-OE) and dominant-negative (HSFA6b-RD) mutant lines. We used microarray to investigate how genes regulated by HSFA6b after NaCl or heat shock treatment.

(Submitter supplied) ChIP-chip analysis was used to identify direct targets of the transcription factor SCR SCARECROW (SCR) is a key regulatory of radial patterning and stem cell renewal in the primary root. We have shown in previous studies that SCR is a direct transcriptional regulator in Arabidopsis thaliana. With the aim of understanding the molecular pathway acting downstream of SCR in primary root development, we identified SCR direct targets at the genome-wide level in primary roots.To do this we designed a promoter microarray (chip) for Arabidopsis containing probes tiling the intergenic regions, first intron, and 3’UTR of all annotated genes. more...

(Submitter supplied) To understand the effect of sulfur deficiency on developmental stages in the root, we dissected the root into four developmental zones after exposure to sulfur deficiency and expression profiled each zone. Stress responses in plants are tightly coordinated with developmental processes, but the interaction between these pathways is poorly understood. Here we use genome-wide assays at high spatial and temporal resolution to understand the processes that lnk development and stress in the Arabidopsis root. more...

We combined these data with 13 other datasests and performed a meta-analysis to ask whether a universal stress response exists in Arabidopsis roots.

(Submitter supplied) Soil salinity increasingly causes crop losses worldwide. Although roots are the primary targets of salt stress, the signaling networks that facilitate metabolic reprogramming to induce stress tolerance are less understood than those in leaves. Here, a combination of transcriptomic and metabolic approaches was performed in salt-treated Arabidopsis thaliana roots, which revealed that the group S1 basic leucine zipper transcription factors bZIP1 and bZIP53 reprogram primary C- and N-metabolism. more...

(Submitter supplied) In view of the continuous salinization of arable lands world-wide, there is an urgent need to better understand the mechanisms underlying plant responses to salt stress at different stages of their development. We investigated the role of calmodulin (CaM)-binding transcription activator 6 (CAMTA6) under salinity stress during early germination in Arabidopsis. These analyses suggest that ABA signaling is involved in CAMTA6-dependent salt-responsive gene expression, consistent with the ABA hyper-tolerance phenotype and the lack of HKT1 response to ABA and NaCl in the camta6 mutants.
