Oxidative environment and redox homeostasis in plants: dissecting out significant contribution of major cellular organelles
*Correspondence: Ashwani Pareek, Stress Physiology and Molecular Biology Laboratory, School of Life Sciences, Jawaharlal Nehru University, Room No. 401, New Delhi 110067, India e-mail: [email protected] Plant cells are often exposed to oxidative cellular environments which result in the generation of toxic reactive oxygen species (ROS). In order to detoxify the harmful ROS, plants have ev...
متن کاملpH Homeostasis of cellular organelles.
An optimal pH is maintained in each secretory and endocytic organelle by the balance between active H(+) pumping and passive H(+) efflux. The progressive acidification of secretory organelles does not reflect an increased proton pumping activity but rather the decreased conduction of a "proton leak" pathway resembling the recently cloned voltage-gated proton channels.

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
Hydrogen Sulfide and Cellular Redox Homeostasis
Intracellular redox imbalance is mainly caused by overproduction of reactive oxygen species (ROS) or weakness of the natural antioxidant defense system. It is involved in the pathophysiology of a wide array of human diseases. Hydrogen sulfide (H2S) is now recognized as the third "gasotransmitters" and proved to exert a wide range of physiological and cytoprotective functions in the biological s...
متن کاملContribution of glutathione to the control of cellular redox homeostasis under toxic metal and metalloid stress.
The accumulation of toxic metals and metalloids, such as cadmium (Cd), mercury (Hg), or arsenic (As), as a consequence of various anthropogenic activities, poses a serious threat to the environment and human health. The ability of plants to take up mineral nutrients from the soil can be exploited to develop phytoremediation technologies able to alleviate the negative impact of toxic elements in...
