Special Issue Information

Dear Colleagues,

Abiotic stress, more specifically, saline and water, poses a significant threat to plant survival and productivity, causing substantial losses in global crop yields. The adverse effects caused by water stress (drought and flood) and saline stress are maximized with environmental conditions. Consequently, there's a pressing need for comprehensive research delving into the molecular, cellular, tissue, anatomical, morphological, and physiological mechanisms underlying plant resilience to salt and water stress.

This Second Edition of the Special Issue in Plants aims to aggregate extensive insights into plant responses to salt and water stress and propose innovative strategies for enhancing their resilience. By synthesizing a wealth of information, we aspire to advance our understanding of plant adaptation mechanisms and foster the development of effective solutions to mitigate the impact of salt and water stress. We invite research articles that address the following topics: ROS; salinity; drought; flood stress; signaling molecules; antioxidants; and oxidative stress. Finally, we are particularly interested in understanding how these combined stresses impact plant responses and adaptations, rather than studying individual stress factors in isolation.

Drought stress and insecticide exposure are two significant environmental factors that can impact the physiology and behaviour of aphids, a major agricultural pest. An understanding of the mechanisms of green peach aphids’ response to insecticides under drought stress is a critical area of research that needs urgent attention. In view of this, we conducted this study to determine the impact of drought and insecticides on the activity of detoxification enzymes in green peach aphid. A 2 × 2 × 3 factorial experiment involving two levels of water treatments (drought and no drought), two levels of aphids infestation (aphids and no aphids), and three levels of pesticides applications (thiacloprid, flonicamid and no pesticide) was conducted. The treatments were arranged in a randomized complete block design with three replications. The results showed that there was a significant (p < 0.01) interaction effect of drought × insecticides on the green peach aphid performance under drought or no drought conditions. Generally, the highest aphids host acceptance, survival rate, colonization success, and average daily reproduction under drought and well-watered conditions occurred on flonicamid-treated plants, whereas thiacloprid-treated plants had the least. However, the thiacloprid-treated plants had higher photosynthetic rate, water use efficiency, lower stomatal conductance, and decreased transpiration rate. Moreover, flonicamid treatment increased the accumulation of glutathione–S-transferase, acetylcholinesterase, butyrylcholinesterase, 1-napthyle acetate, and 1-napthyle butyrate activities in aphids, compared to the thiacloprid treatments. The thiacloprid pesticide, which demonstrated higher efficacy against green peach aphid, can be used in areas where green peach aphids and drought stress are major concerns. Full article
