Carbohydrates and polyphenolics of extracts from genetically altered plant acts as catalysts for in vitro synthesis of silver nanoparticle.

Eco-friendly biosynthetic approach for silver nanoparticles production using plant extracts is an exciting advancement in bio-nanotechnology and has been successfully attempted in nearly 41 plant species. However, an established model plant system for systematically unraveling the biochemical components required for silver nanoparticles production is lacking. Here we used as the model plant for silver nanoparticles biosynthesis .

Innate CD8αα lymphocytes enhance anti-CD40 antibody-mediated colitis in mice.

Introduction: Immune responses in the intestines require tight regulation to avoid uncontrolled inflammation. We previously described an innate lymphocyte population in the intestinal epithelium (referred to as innate CD8αα , or iCD8α cells) that can protect against gastrointestinal infections such as those mediated by Citrobacter rodentium.

Methods: Here, we have evaluated the potential contribution of these cells to intestinal inflammation by analyzing inflammation development in mice with decreased numbers of iCD8α cells.

Environmental stress influencing plant development and flowering.

Plants are sessile organisms and unlike animals, cannot run away from adverse environmental conditions. Therefore, they have evolved sophisticated signaling and protective systems to overcome sub-lethal stress situations. Although, effect of stress on physiology and morphology were studied earlier, the research on molecular mechanisms of stress response is albeit new.
