Plants are exposed under natural conditions multiple environmental stresses. Abiotic stress includes salinity, drought, floods (submergence stress), temperature extremes, heavy metals, etc. The plants have no choice to escape from these environmental hazards due to they are sessile in nature. These abiotic stresses negatively impact on the growth and productivity. It is also known that plant responses depend largely on the affected tissues or organs. Lately, plants have developed the numerous approaches and mechanisms have been used to overcome these stresses.

There are different methods in which various materials, including mineral, biological, and organic, are used, can overcome the negative effects of abiotic stresses, or at least mitigate those effects. These are affordable and can be used practically. On the other hand, Therefore, it is important to evaluate and explore how various molecular techniques can be applied to biological studies to improve plant tolerance to abiotic stress. From this standpoint, there is an urgent need to shed light on plant stress research, especially with the use of modern methods and materials to overcome the negative effects of these stresses, in order to understand the nature of the multiple responses to stress and to find ways to develop plants that resist multiple stresses while encouraging the highest productivity. This special issue is concerned with the influences of abiotic stress on plants, focusing on work on physiological and molecular mechanisms or any anatomical or morphological adaptations.

The guest-editor encourages scientists to contribute original papers or reviews relevant to the effects of any abiotic environmental stresses on plants and this would be most welcomed.

    Research Progress on Plant Anti-Freeze Proteins

    Abstract Plant antifreeze proteins (AFPs) are special proteins that can protect plant cells from ice crystal damage in low-temperature environments, and they play a crucial role in the process of plants adapting to cold environments. Proteins with these characteristics have been found in fish living in cold regions, as well as many plants and insects. Although research on plant AFPs started relatively late, their application prospects are broad, leading to the attention of many researchers to the isolation, cloning, and genetic improvement of plant AFP genes. Studies have found that the distribution of AFPs in different species… More >

    Physiological Mechanism of Exogenous Selenium in Alleviating Mercury Stress on Pakchoi (Brassica campestris L.)

    Abstract The objective of this study was to explain the physiological mechanisms through which NaSeO mitigates the growth and developmental inhibition of pakchoi under HgCl stress. The results showed that treatment with HgCl (40 mg L) led to reduced biomass, dwarfing, root shortening, and root tip necrosis in pakchoi. Compared to control (CK), the activities of superoxide dismutase (SOD) and peroxidase (POD) in Hg treatment increased, and the content of malondialdehyde (MDA) also dramatically increased, which negatively impacted the growth of pakchoi. Low concentrations of NaSeO (0.2 mg L) significantly increased the content of soluble sugars… More >

    Effects of Different Light Qualities on the Growth Characteristics of Populus trinervis

    Jiaqi Li, Zhensheng Qiao, Dan Zong, Chengzhong He
    Phyton-International Journal of Experimental Botany, Vol.93, No.5, pp. 1043-1056, 2024, DOI:10.32604/phyton.2024.050637

    Abstract Populus trinervis is native to China and plays an irreplaceable role in maintaining the ecological balance of boreal and temperate forests. P. trinervis mainly grows in high-altitude areas. At present, there are limited studies on the response of P. trinervis to different light qualities, so it is necessary to investigate the photosynthetic physiological changes of P. trinervis in different light environments. In our study, P. trinervis was grown for 8 months under light filtered by three different colored films. The three treatments were blue film, green film, and white plastic film. The effects of blue (B), green (G), and white… More >
