“…Acid rain has a very negative effect on plants, leading to characteristic symptoms of leaf damage, biochemical, ultrastructural and functional changes in the photosynthetic apparatus [23], the mechanisms of which have not yet been fully studied. Since ATP hydrolysis in chloroplasts is a process in which energy stored at photosynthesis unproductively dissipates the increase in hydrolytic activity of the catalytic part of the chloroplast H + -ATP synthase (factor CF 1 ) under the action of sulfite from acid rainfall may be one of the mechanisms of the negative impact of such an anthropogenic phenomenon as acid rain.…”

The present study of sulfite participation in the regulation of the chloroplast ATP-synthase complex can help to understand the mechanisms of acid rains toxic effects on the plant photosynthetic apparatus. The aim of the work was to study the effect of sulfite on Ca 2+-and Mg 2+-dependent AtP hydrolysis catalysed by coupling factor CF 1 , exposed to preliminary short-term acid treatment. CF 1 was isolated from spinach chloroplasts (Spinacia oleracea L.). The latent ATPase activity of CF 1 was activated by sodium sulfite addition into incubation media. The rate of ATP hydrolysis was determined by the release of inorganic phosphate. In the presence of 25 mM exogenous sulfite the Mg 2+-dependent hydrolytic activity of CF 1 was increased 7-fold and ca 2+-dependent activity 3-fold compared to the control. carbonic anhydrase inhibitors acetazolamide or ethoxyzolamide eliminated sulfite-induced stimulation of ATP hydrolysis. The sulfite stimulating effect on Ca 2+and Mg 2+-ATPase activity was increased dramatically after incubation (5 min) of isolated CF 1 in a medium with pH 3.5 and its subsequent transition to the alkali medium (pH 8.0). In this case, 1 mM sulfite-induced a 10-fold acceleration of ATP hydrolysis. Carbonic anhydrase specific inhibitors (50 μM) removed the sulfite effect. These data suggest that sulfite was able to replace bicarbonate in the CF 1 structure after the release of bound hcO 3 during acid treatment.

“…It has been observed that acid rain deposition in the plant caused the ultrastructural changes mainly in the mesophyll, chloroplasts, and mitochondria of the leaf, which resulted in the extreme production of ROS [ 8 , 9 ]. Also, plant exposed to acid rain resulted in characteristic foliar injury symptoms, modified leaf anatomy and necrosis, decrease in the chlorophyll concentration, and altered respiration and photosynthesis [ 10 , 11 ]. Moreover, decreasing of photosynthetic rate and chlorophyll content which hamper the normal plant growth by altering the antioxidant activities because of AR [ 12 ].…”

Exogenous Melatonin Mitigates Acid Rain Stress to Tomato Plants through Modulation of Leaf Ultrastructure, Photosynthesis and Antioxidant Potential

et al. 2018

Acid rain (AR) is a serious global environmental issue causing physio-morphological changes in plants. Melatonin, as an indoleamine molecule, has been known to mediate many physiological processes in plants under different kinds of environmental stress. However, the role of melatonin in acid rain stress tolerance remains inexpressible. This study investigated the possible role of melatonin on different physiological responses involving reactive oxygen species (ROS) metabolism in tomato plants under simulated acid rain (SAR) stress. SAR stress caused the inhibition of growth, damaged the grana lamella of the chloroplast, photosynthesis, and increased accumulation of ROS and lipid peroxidation in tomato plants. To cope the detrimental effect of SAR stress, plants under SAR condition had increased both enzymatic and nonenzymatic antioxidant substances compared with control plants. But such an increase in the antioxidant activities were incapable of inhibiting the destructive effect of SAR stress. Meanwhile, melatonin treatment increased SAR-stress tolerance by repairing the grana lamella of the chloroplast, improving photosynthesis and antioxidant activities compared with those in SAR-stressed plants. However, these possible effects of melatonin are dependent on concentration. Moreover, our study suggests that 100-μM melatonin treatment improved the SAR-stress tolerance by increasing photosynthesis and ROS scavenging antioxidant activities in tomato plants.

“…Photosynthesis is the basis of plant survival and is the complex process to change the light energy into chemical energy (Bernacchi et al 2013). At the same time, under the environmental stress, photosynthetic rate is also an important indicator to evaluate the plant resistance (Polishchuk et al 2016;Sun et al 2016;Hu et al 2016a, b). Higher Pn indicates the more organic matter is synthesized in plants, and the more energy for consumption, the stronger is the ability to resist environmental stress.…”

Paclobutrazol (PAC), as a commonly used plant regulator, has the important function of improving the plant’s stress resistance. Sequoia sempervirens Endl. is a large caliber, fast-growing timber species and one of the world’s five major landscaping tree species. This study researched the effects of spraying PAC on the growth and photosynthetic activity of S. sempervirens seedlings. The results showed the plant height and the plant crown diameter were decreased significantly with the increase in PAC concentration (500 – 3,000 mg·dm−3). However, the ground shoot diameter, net photosynthetic rate, stomatal conductance, inter-cellular CO2 concentration, transpiration rate, actual photochemical quantum yield, and photosynthetic electron transport rate all showed the trend of increasing first reaching the maximum at 2,000 mg·dm−3 and then decreased. Water use efficiency showed the opposite trend. Spraying 2 times was better than once. The conclusion suggests that PAC can protect the photosynthetic activity and improve the resistance of S. sempervirens seedlings under natural cooling and draught in autumn and winter.
