The Transcription Stress Response

Monitoring Response of a Few bZip Transcription Factors in Response to Osmotic Stress in Sunflower

Background: Sunflower (Helianthus annuus L.) is one of the important vegetable oil supplies in the world and in Iran, as well. It is classified as a drought semi-tolerant crop; however, its yield is adversely affected by drought stress. Understanding the initial events in sensing stress and the related physiologic and biochemical events thereafter, is crucial in designing droug...

Mediator phosphorylation prevents stress response transcription during non-stress conditions.

The multiprotein complex Mediator is a coactivator of RNA polymerase (Pol) II transcription that is required for the regulated expression of protein-coding genes. Mediator serves as an end point of signaling pathways and regulates Pol II transcription, but the mechanisms it uses are not well understood. Here, we used mass spectrometry and dynamic transcriptome analysis to investigate a function...

Conditions Response Transcription During Non - stress Mediator Phosphorylation Prevents Stress

Expression pattern analysis of transcription factors from Aeluropus littoralis in response to salt stress and recovery condition.

Salinity is one of the most important abiotic stresses that decrease crop production. Transcription factors (TFs) are prominent regulators in plant responses to abiotic stress. In the present study, the expression pattern of four salt-induced genes encoding transcription factors, namely, MYB, RF2, GTF, and ARID was studied in response to salt stress (sodium chloride) and recovery conditions. Th...

Luman/CREB3 induces transcription of the endoplasmic reticulum (ER) stress response protein Herp through an ER stress response element.

Luman/CREB3 (also called LZIP) is an endoplasmic reticulum (ER) membrane-bound transcription factor which is believed to undergo regulated intramembrane proteolysis in response to cellular cues. We previously found that Luman activates transcription from the unfolded protein response element. Here we report the identification of Herp, a gene involved in ER stress-associated protein degradation ...
