Gene Expression and Signal Transduction in Water-Stress Response

Gene Expression and Signal Transduction in Water-Stress Response.

Land plants suffer from dehydration or water stress not only under drought and high-salt-concentration conditions but also under low-temperature conditions. They respond and adapt to water stress to survive these environmental stress conditions. Water stress induces various biochemical and physiological responses in plants. Under water-stress conditions plant cells lose water and decrease turgo...

Isolation of Brassica napus MYC2 gene and analysis of its expression in response to water deficit stress

Manipulation of stress related transcription factors to improve plant stress tolerance is a major goal of current biotechnology researches. MYC2 gene encodes a key stress-related transcription factor involved in Jasmonate (JA) and abscisic acid (ABA) signaling pathways in Arabidopsis. Brassica napus, as a globally important oilseed crop, is a close relative of Arabidopsis.  In the present study...

Chromium stress response effect on signal transduction and expression of signaling genes in rice.

Hexavalent chromium [Cr(VI)] is a non-essential metal for normal plants and is toxic to plants at high concentrations. However, signaling pathways and molecular mechanisms of its action on cell function and gene expression remain elusive. In this study, we found that Cr(VI) induced endogenous reactive oxygen species (ROS) generation and Ca(2+) accumulation and activated NADPH oxidase and calciu...

Changes in gene expression and signal transduction following ibogaine treatment.

The Expression of Signal Regulatory Protein-alpha in Normal and Osteoarthritic Human Articular Cartilage and Its Involvement in Chondrocyte Mechano-transduction Response

Signal regulatory proteins (SIRP) belong to immunoglobulin super family (IgSF) and relate to integrin signaling cascades. It has been shown that SIRPa is expressed in a variety of cells including myeloid cells and neurons. In the present study the expression of this IgSF member in articular chondrocytes was investigated. Methods: Using a panel of anti-SIRPalpha antibodies, immunohistochemistry...
