Plants encounter various abiotic stresses due to their sessile nature which include heavy
metals, salt, drought, nutrient deficiency, light intensity, pesticide contamination, as well as …

Plants as sessile organisms are continuously exposed to abiotic stress conditions that
impose numerous detrimental effects and cause tremendous loss of yield. Abiotic stresses …

Oxygen is a natural acceptor of electrons in the respiratory pathway of aerobic organisms
and in many other biochemical reactions. Aerobic metabolism is always associated with the …

▪ Abstract Photoreduction of dioxygen in photosystem I (PSI) of chloroplasts generates
superoxide radicals as the primary product. In intact chloroplasts, the superoxide and the …

Photosynthesis in warm-climate plants is substantially reduced after chilling. Tropical and
subtropical species offer the opportunity to study the effects of low temperature on …

Abstract Photosystem I (PS I) photoinhibition suppresses plant photosynthesis and growth.
However, the mechanism underlying PS I photoinhibition has not been fully clarified. In this …

Photosynthesis uses sunlight to convert water and carbon dioxide into biomass and oxygen.
When in excess, light can be dangerous for the photosynthetic apparatus because it can …

During the past few years, considerable progress has been made in understanding how
plants protect themselves against oxidative stress. Genes encoding plant antioxidant …

Chloroplasts are the organelles that perform energy transformation in plants. The normal
physiological functions of chloroplasts are essential for plant growth and development …
