Acid rain can directly or indirectly affect plant physiological functions, especially photosynthesis. The enzyme ATP synthase is the key in photosynthetic energy conversion, and thus, it affects plant photosynthesis. To clarify the mechanism by which acid rain affects photosynthesis, we studied the effects of acid rain on plant growth, photosynthesis, chloroplast ATP synthase activity and gene expression, chloroplast ultrastructure, intracellular H+ level, and water content of rice seedlings… 
Photosynthetic rate and chlorophyll fluorescence of barley exposed to simulated acid rain
A glasshouse experiment was conducted, and the photosynthetic rate, chlorophyll (Chl) fluorescence, and pigment content of barley were measured in simulated acid rain (SAR), suggesting that photosynthesis in barley plants was inhibited by SAR stress.
Dual Role of Acid Rain and Pyricularia oryzae on Growth, Photosynthesis and Chloroplast Ultrastructure in Rice Seedlings
Rice is widely planted and serves as staple food in the world, but it is often exposed to acid rain and rice blast (Pyricularia oryzae). In this work, we analyzed the effects of co-exposure to
Effects of Silicon on the Growth, Photosynthesis and Chloroplast Ultrastructure of Oryza sativa L. Seedlings under Acid Rain Stress
Silicon (Si) is a beneficial element for plants and can increase plant resistance. In the present work, a hydroponic experiment was carried out to study the effects of Si on the growth and
Acidic and Alkaline Conditions Affect the Growth of Tree Peony Plants via Altering Photosynthetic Characteristics, Limiting Nutrient Assimilation, and Impairing ROS Balance
Exposure to acidic and alkaline conditions were found to cause the excess accumulation of reactive oxygen species in tree peony, thereby causing damage and inhibiting plant growth and development.
Alleviative effects of nitric oxide on Vigna radiata seedlings under acidic rain stress.
Overall, the application of exogenous sodium nitroprusside at 0.25 mM SNP eliminated reactive oxygen species (ROS) by stimulating antioxidant enzyme activities, reducing oxidative stress and mitigating the toxic effects of SAR on mung bean seedlings.
Effects of cadmium and simulated acid rain on growth and physiological characteristics of bermudagrass seedling
The effects of cadmium (Cd) and acid rain on the growth of bermudagrass were studied by hydroponic experiment. This study was divided into two separate experimental groups. In the first one, we


Combined Effects of Lead and Acid Rain on Photosynthesis in Soybean Seedlings
The inhibition of the photosynthetic process is an important physiological basis for the simultaneous actions of Pb and acid rain in soybean seedlings.
Response of plasma membrane H+-ATPase in rice (Oryza sativa) seedlings to simulated acid rain
It is suggested that plasma membrane H+-ATPase can play a role in adaptation to acid rain for rice seedlings and alleviated damage in leaves treated with pH 2.5 acid rain is suggested.
Water stress inhibits plant photosynthesis by decreasing coupling factor and ATP
It is shown that ATP-synthase (coupling factor) decreases with stress and concluded that photosynthetic assimilation of CO2 by stressed leaves is not limited by CO2 diffusion but by inhibition of ribulose biphosphate synthesis, related to lower ATP content resulting from loss of ATP synthase.
Interactive effects of cadmium and acid rain on photosynthetic light reaction in soybean seedlings.
Thiol modulation of the chloroplast ATP synthase is dependent on the energization of thylakoid membranes.
T thorough analysis of the redox state of regulatory cysteines of the chloroplast ATP synthase γ subunit in intact chloroplasts and leaves shows that thiol modulation of this enzyme is pivotal in prohibiting futile ATP hydrolysis activity in the dark, but the physiological importance of efficient ATP synthesis driven by the reduced enzyme in the light could not be demonstrated.
ATPG is required for the accumulation and function of chloroplast ATP synthase in Arabidopsis
It is suggested that ATPG was essential for the accumulation and function of chloroplast ATP synthase.
[Effects of simulated acid rain on oilseed rape (Brassica napus) physiological characteristics at flowering stage and yield].
With the increasing acidity of simulated acid rain, the pod number per plant and the seed number per pod decreased significantly, while the seed weight was less affected, and different yield components showed different sensitivity to simulated acidRain.
Photosynthesis and ultrastructure of photosynthetic apparatus in tomato leaves under elevated temperature
Generally, the photosynthetic apparatus of tomato changed significantly and the changed chloroplast ultrastructure might be one of the important reasons that caused the decrease of PN under 35°C.
