Mediator Phosphorylation Prevents Stress Response Transcription During Non-stress Conditions

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...

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...

Evaluation of Drought Tolerance in Safflower (Carthamus Tinctorius L.)Under non Stress and Drought Stress Conditions

This study was conducted to determine drought tolerance genotypes with superiority in different stressed environments. To screening quantitative indices of drought tolerance, genotypes of safflower (Carthamus tinctorius L.) were tested in a complete randomized block design with three replications under two different water regimes (irrigated and rainfed). Significant positive correlatio...
