Summary

In the era of climate change, abiotic stresses (e.g., salinity, drought, extreme temperature, flooding, heavy metal, UV radiation, ozone, etc.) are considered as one of the most complex environmental constraints that restricts crop production worldwide. With the present global climatic change, these abiotic stress factors are taking place more frequently than earlier times leading to the vulnerability of crop productivity, and creating challenges for the farming community to feed the ever-growing population of this universe. Facing this fact, plant biologists are trying to develop new technologies towards sustaining crop productivity. Introduction of stress-tolerant crop cultivars is the most auspicious way of surviving this constraint, and to produce these types of tolerant crops. To address this issue researchers are working in understanding the physiological and molecular mechanisms of abiotic stress responses and tolerance. A remarkable progress has also been made in developing crop varieties tolerant to environmental stress. This special issue is indented to bring together a galaxy of eminent experienced scientists to present latest developments in this field.

Potential topics may include, but are not limited to:
1) Overview of abiotic stress;
2) Crop plants responses and tolerant to salinity;
3) Crop plants responses and tolerant to drought;
4) Crop plants responses and tolerant to excess water;
5) Crop plants responses and tolerant to toxic metals/metalloids;
6) Crop plants responses and tolerant to high temperature;
7) Crop plants responses and tolerant to low temperature;
8) Crop plants responses and tolerant to atmospheric pollutants;
9) Crop plants responses and tolerant to high light;
10) Biotechnological tools in developing abiotic stress tolerance;
11) Agronomic approaches in mitigating abiotic stress;
12) Use of exogenous protectants in mitigating abiotic stress.

Published Papers
  • Assessment of Castor Plant (Ricinus communis L.) Tolerance to Heavy Metal Stress-A Review
  • Abstract Increased urbanization and industrialization have greatly contributed to the emission of higher amount of heavy metals such as cadmium, nickel, and lead into the environment. These metals are non-biodegradable and toxic, causing much effects on plants and by extension to animals and humans, which have become a major global concern. The inherent ability of plants to resist heavy metal toxicity seems to be the most sustainable and cost-effective strategy. Castor plant is widely studied due to its tolerance to the effects of heavy metal contaminated soils, owing to its large biomass content and high accumulating capacity. Castor plants to some… More

  • Oxidative Stress Tolerance Mechanism in Rice under Salinity
  • Abstract The research was conducted to investigate comparative oxidative damage including probable protective roles of antioxidant and glyoxalase systems in rice (Oryza sativa L.) seedlings under salinity stress. Seedlings of two rice genotypes: Pokkali (tolerant) and BRRI dhan28 (sensitive) were subjected to 8 dSm−1 salinity stress for seven days in a hydroponic system. We observed significant variation between Pokkali and BRRI dhan28 in phenotypic, biochemical and molecular level under salinity stress. Carotenoid content, ion homeostasis, antioxidant enzymes, ascorbate and glutathione redox system and proline accumulation may help Pokkali to develop defense system during salinity stress. However, the activity antioxidant enzymes particularly… More

  • Salt-Induced Changes in Physio-Biochemical and Antioxidant Defense System in Mustard Genotypes
  • Abstract Salinity stress is a major factor limiting plant growth and productivity of many crops including oilseed. The present study investigated the identification of salt tolerant mustard genotypes and better understanding the mechanism of salinity tolerance. Salt stresses significantly reduced relative water content (RWC), chlorophyll (Chl) content, K+ and K+ /Na+ ratio, photosynthetic rate (PN), transpiration rate (Tr), stomatal conductance (gs), intercellular CO2 concentration (Ci) and increased the levels of proline (Pro) and lipid peroxidation (MDA) contents, Na+ , superoxide (O2•− ) and hydrogen peroxide (H2O2) in both tolerant and sensitive mustard genotypes. The tolerant genotypes maintained higher Pro and lower… More

  • Physiological Responses of Dendrobium officinale under Exposure to Cold Stress with Two Cultivars
  • Abstract This study aimed to explore the cold tolerance of two cultivars of Dendrobium officinale (MG1, MG2) grown in different regions of China. Under -2°C incubation, cultivar MG1 remained active after 3 d, and continued to grow after returning to room temperature. However, MG2 could only maintain its activity after 2 d treatment at −2°C, and the seedlings died with the low temperature treatment time. Investigation of the characteristics of the plants grown in the south (Hangzhou) or north (Zhengzhou) of China indicated that the leaves of MG1 also had reduced stomatal density, the highest thickness, and a compact microstructure. The… More
