Food-based exposure to arsenic is a human carcinogen and can severely impact human health resulting in many cancerous diseases and various neurological and vascular disorders. This project is a part of our attempts to develop new varieties of crops for avoiding arsenic contaminated foods. For this purpose, we have previously identified four key genes, and molecular functions of two of these, AtACR2...
Arabidopsis ICR1 (AtICR1) has been identified as a specific effector of Rho family small GTPases (ROP) in Arabidopsis thaliana. Previous researches have suggested that AtICR1 could function as scaffold linking ROP GTPases with vesicle trafficking and differentiation of cell polarity. To further explore whether AtICR1 is involved in potential regulation of other developmental pathways (such as anthesis),...
Guard cells can integrate and process multiple complex signals from the environment and respond by opening and closing stomata in order to adapt to the environmental conditions changing. Over the past several years, considerable research progress has been made in our understanding of the role of calcium (Ca2+), nitric oxide (NO) and hydrogen peroxide (H2O2) as essential signal molecules that mediate...
Exposure of Arabidopsis leaves to cadmium (Cd) stress led to an increase in the level of extracellular ATP (eATP). And, Cd stress also caused significant increases in lipid peroxidation and the activities of lipoxygenase (LOX) and antioxidant enzymes, including superoxide dismutase (SOD), peroxidase (POX), and catalase (CAT). Treatment of Arabidopsis leaves with β,γ-methyleneadenosine 5’-triphosphate...
