Summary

The frequency of extreme events is on the rise due to climate change, which is negatively impacting the growth, development, and yield of relevant commodities. This has significant implications for global food security. Conversely, potential solutions may enhance plant metabolism and mitigate abiotic and biotic stresses.  Consequently, in the current global environment, it is imperative to conduct research and develop cost-effective, modern solutions based on sustainable technologies to enhance plant tolerance to climate change and ensure food security. This topical collection is open to novel research, meta-analyses, and reviews that address all topics related to potential solutions based on plant growth regulators, including biostimulants, biopesticides, nanoparticles, brassinosteroids, gasotransmitters, microorganisms, phytohormones, neurotransmitters, and chemical elements. The focus is on mitigating abiotic and biotic stresses, including drought, flooding, salinity, toxic metals, low or high temperatures, low or high irradiance, acid rain, nutritional stress, plant diseases, and insect pests.

    Abstract Nickel (Ni) is an essential metallic micronutrient for optimal plant growth and development, regulator of essential metabolic processes, but its interaction with other essential nutrients can result in differences in the absorption of these nutrients, which can disrupt the ionic balance. The objective of this research was to evaluate the physiological performance and growth of soybean plants subjected to Ni levels applied via soil under Fe (iron) excess, determining the behavior of redox metabolism, gas exchange, and photosynthetic pigments. The experiment was conducted in a completely randomized design with a factorial 2 × 3, with… More >
