Plant Stress Physiology and Heavy Metal Tolerance Mechanisms
This community investigates how crops and model plants physiologically respond to environmental stressors, specifically heavy metal contamination and abiotic challenges like drought and salinity, to understand the biochemical pathways that allow them to survive and grow.
The research focuses heavily on the mechanisms of cadmium uptake, accumulation, and toxicity in rice, wheat, and maize. A central theme is the role of reactive oxygen species (ROS) and antioxidant defense systems in mitigating oxidative damage caused by these stressors. The work frequently examines the physiological and biochemical responses to salt and drought stress, often exploring how exogenous applications of silicon, salicylic acid, or arbuscular mycorrhizal fungi can enhance stress tolerance. The literature also addresses phytoremediation strategies, analyzing how plants can be managed to reduce the transfer of heavy metals like arsenic and lead into the food chain or to remediate contaminated soils.
The largest share of the community's output is found in cadmium research, representing 8.1% of all cadmium research, and 13,659 papers here. Arsenic and lead also feature prominently, with 3.0% and 2.1% shares of their respective element research.
The community comprises 60,327 papers, published most frequently in Frontiers in Plant Science, Ecotoxicology and Environmental Safety, and Environmental Science and Pollution Research.
Recent work continues to focus on the molecular regulation of ROS and antioxidant defenses, with specific studies examining how boron and silicon nanoparticles can inhibit cadmium uptake or boost salinity resilience in rice.
