“…This may be due to the adverse conditions that reduced the activity of protein synthetase or increased the activity of the enzyme in the plant, resulting in a decrease in the protein content. This result is similar to that presented by Gilmour et al [8]. During the freezing period, the protein content of the combined stress group and the freeze-thaw group reached a peak at 0°C, and that of each test group showed a downward trend from 0 to -3°C, indicating that low temperature decreased the plant protein content.…”

BackgroundIn the early spring of northern China, the combined stresses of freeze-thaw, deicing salt and acid deposition are the main ecological threats to the urban turf ecosystem. ResultsWe studied changes in the Malondialdehyde (MDA), protein, soluble sugar, proline and chlorophyll contents of DongMu No. 1seedlings of 8 treatment combination groups which are imposed by freeze-thaw (F), acid rain (A) and deicing salt (D). An increasing in MDA content showed that the membrane system of seedlings was damaged under combined stress (F+A+D). The changes indicated that under the adverse conditions, the proline and soluble sugar contents increased obviously with the accumulation of MDA in the plants, while the chlorophyll content decreased significantly.ConclusionPlants can alleviate the damage caused by stress by increasing soluble sugars and by regulating the proline content to maintain osmotic balance.

“…Environmental stress can disrupt the homeostasis of cells and the dynamic balance between production and clearance of ROS, leading to excessive accumulation of ROS in cells, causing the oxidative damage to biomolecules such as lipids [27], proteins [28] and nucleic acids [29], and the disruption of osmotic balance in plants [30], which were discussed in detail in numerous studies. MDA is the end product of lipid peroxidation and can be induced by stress in plants organ, e.g.…”

Background Qinghai-Tibet Plateau is known for characteristics of high altitude, low rainfall and varying temperature, and the crops in this area are susceptible to abiotic stresses such as drought, basic salt and freeze-thaw that caused damages in different perspectives such as the permeability of biological membrane, osmotic adjustment, and antioxidant enzyme system. Hordeum vulgare L. is an indispensable crop in plateau and plays an important role in agricultural ecosystem as well.Result In this experiment, H. vulgare L. was used as experimental material and the physiological characteristics soluble protein (SP) content, malondialdehyde (MDA) content, antioxidant enzyme activity and relative water content (RWC) of seedlings were examined under freeze-thaw condition combined with drought and alkali stress.Conclusion Research results indicated that under the combined stresses of basic salt and drought, H. vulgare L. seedlings were damaged by lipid peroxidation, weakened superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) activities, while enhanced osmotic adjustment ability in plants cell. It was suggested that, in agricultural management, the simultaneous occurrence of two stresses, basic salt and drought, should be avoided in the early stage of H. vulgare L. planting to reduce the physiological stress on plants.

“…Samples (1 g) were then extracted with 8 ml of distilled water and incubated for 1 h, after which the extracts were centrifuged at 500 g for 20 min at 4 °C. The amount of soluble protein was subsequently determined by the Bradford method using bovine serum albumin [ 27 , 28 ]. The soluble protein concentrations were expressed as milligrams per gram of fw.…”

Nitrogen dioxide (NO2) at a high concentration is among the most common and harmful air pollutants. The present study aimed to explore the physiological responses of plants exposed to NO2. A total of 41 plants were classified into 13 functional groups according to the Angiosperm Phylogeny Group classification system. The plants were exposed to 6 μL/L NO2 in an open-top glass chamber. The physiological parameters (chlorophyll (Chl) content, peroxidase (POD) activity, and soluble protein and malondialdehyde (MDA) concentrations) and leaf mineral ion contents (nitrogen (N+), phosphorus (P+), potassium (K+), calcium (Ca2+), magnesium (Mg2+), manganese (Mn2+), and zinc (Zn2+)) of 41 garden plants were measured. After NO2 exposure, the plants were subsequently transferred to a natural environment for a 30-d recovery to determine whether they could recover naturally and resume normal growth. The results showed that NO2 polluted the plants and that NO2 exposure affected leaf Chl contents in most functional groups. Increases in both POD activity and soluble protein and MDA concentrations as well as changes in mineral ion concentrations could act as signals for inducing defense responses. Furthermore, antioxidant status played an important role in plant protection against NO2-induced oxidative damage. NO2 poses a pollution risk to plant systems, and antioxidant status plays an important role in plant protection against NO2-induced oxidative damage. In conditions of strong air pollution, more evergreen plants may be considered in landscape design, particularly in seasonal regions. The results of this study may provide useful data for the selection of landscaping plants in NO2 polluted areas.
