Expression data in an Arabidopsis cytokinin (CK)-signaling mutant, ahp2,3,5 and arr1,10,12, and its wild type plant (WT, Col-0) under high salinity (200 mM NaCl) and control (0 mM NaCl) conditions.

To understand the role of CK-signaling components, AHPs (His-containing phosphotransfer proteins) and type-B ARRs (response regulators) in salt stress response, we have employed transcriptional profiling of ahp2,3,5 and arr1,10,12, and it's wild type plant (WT), Col-0 under high salinity (200 mM NaCl) and control (0 mM NaCl) conditions. Agilent’s Whole Arabidopsis Gene Expression Microarray (G2519F-021169, V4, 4x44K) was used. 10-day-old ahp2,3,5, arr1,10,12, and Col-0 plants grown on MS media to were transferred to 0.5 x MS supplemented with 200 mM NaCl (salt stress) or 0 mM NaCl (control), collected just after 24 hours. Total RNA was prepared and used for the microarray hybridization. Three replicative hybridization experiments were carried out for each independent biological sample.
