HAL2 overexpression induces iron acquisition and enhanced salt resistance in bdf1Δ

ABSTRACT: The strain bdf1Δ+HAL2 improved salt resistance of bdf1∆. To gain further insight into the mechanism of bdf1∆ salt sensitivity, DNA microarray analysis was performed to determine the reason for the salt sensitivity of bdf1∆ cells and the process of how HAL2 overexpression and HDA1 deletion improves salt resistance. Transcriptomic analysis under salt treatment (0.5 mol.L-1 NaCl for 45 min) was performed using four different strains: bdf1∆, W303, bdf1Δ+HAL2 and bdf1∆hda1∆. The transcription of 1,393 genes were significantly changed( > 2-fold) in bdf1∆ compared with W303 upon NaCl stress (0.5 mol.L-1 NaCl for 45 min). Only 108 genes were significantly changed ( > 2-fold) in bdf1Δ+HAL2 compared with bdf1∆ upon NaCl stress (0.5 mol.L-1 NaCl for 45 min). Only 88 genes were significantly changed ( > 2-fold) in bdf1Δ+HAL2 compared with bdf1∆ upon NaCl stress (0.5 mol.L-1 NaCl for 45 min).

The transcriptomic changes affected by BDF2 and SIR2 under salt stress

Project description:The strain bdf1∆bdf2∆[BDF2 L][SIR2 H] improved salt resistance of bdf1∆. To gain further insight into the mechanism of BDF1 in suppressing bdf1∆ salt sensitivity, DNA microarray analysis was performed to determine the reason for the salt sensitivity of bdf1∆ cells and the process of how coexpression of SIR2 and BDF2 improves salt resistance. Transcriptomic analysis under salt treatment (0.6 mol.L-1 NaCl for 45 min) was performed using three different strains: bdf1∆bdf2∆[BDF2 L][SIR2 H], bdf1∆bdf2∆[BDF2 L][pYX242] and bdf1∆[pRS316][pYX242]. The transcription of 3244 genes were significantly changed( > 2-fold) in bdf1∆bdf2∆[BDF2 L][SIR2 H] compared with bdf1∆[pRS316][pYX242] upon NaCl stress (0.6 mol.L-1 NaCl for 45 min). Only 281 genes were significantly changed ( > 2-fold) in bdf1∆bdf2∆[BDF2 L][pYX242] compared with bdf1∆[pRS316][pYX242] upon NaCl stress (0.6 mol∙L-1 NaCl for 45 min). BF2:bdf1∆[pRS316][pYX242]. BF2B: bdf1∆bdf2∆[BDF2 L][pYX242]. BF2S:bdf1∆bdf2∆[BDF2 L][SIR2 H].

Rhodobacter sphaeroides salt stress response

Project description:Two excessive NaCl concentrations (0.25% and 1.5%) and two periods of treatment (7 min and 45 min) were used as moderate- and high-salt sress conditions at early and later stages of response, respectively. As a baseline, samples from cells grown on a standard SIS medium in the same growing system and same illumination were used. Keywords: time course and dose response

RNA-seq analysis of gene expression in Helicobacter pylori expressing either WT Fur or a Fur variant (Fur-R88H).

Project description:Purpose: Next-generation sequencing (NGS) was used to analyze gene expression in H. pylori strains expressing either WT Fur or a Fur variant (i.e. Fur-R88H). The goals of this study are to examine the role that WT Fur and Fur-R88H play in affecting salt-responsive gene expression in the 2 different strains. The H. pylori strains were grown in the presence of routine salt (0.5% added NaCl) or high salt (1.0% added NaCl).

della-regulation of salt stress responses-DELLAs contribute to salt stress responses

Project description:rs06-07_della - della-regulation of salt stress responses - Identification of DELLA-dependent dowtream targets in response to salt stress - Aim was to determine downstream target of DELLA proteins involved in salt stress tolerance. Wt, ga1-3, penta seeds were sterilized, sown on MS agar plates then put for stratification for 3 days at 4degreeC. Plates were placed in growth cabinet for 9 days. Seedlings were transferred to 24 well-plates, with 2 seedlings per well (0.5 ml MS liquid per well). Plates were placed in the same condition for 3 days. Finally, NaCl were added (final concentration 200 mM), except for the control. The salt treatment was applied for 30 min and 1h. Treatment was stopped by freezing in liquid nitrogen.
