Summary

Climate change presents multifaceted stressors that profoundly affect plant physiology, biochemistry, and ecology in terrestrial and aquatic environments. Fluctuations in temperature, altered precipitation patterns, increased atmospheric CO2 levels, and changes in water availability and quality pose significant challenges to plant survival and productivity. Understanding these complex interactions is crucial for developing strategies to enhance plant resilience and maintain ecosystem health.


This Special Issue, "Integrative Approaches to Plant Stress Responses under Changing Climate Conditions," aims to advance our understanding of how plants respond to combined stressors in soil and water environments. We seek research that elucidates the mechanisms of stress tolerance at molecular, cellular, and organismal levels and examines the ecological consequences of climate-induced stress on plant communities.


We aim to fill existing knowledge gaps and propose novel approaches to mitigate adverse effects on plants in changing environmental conditions. By integrating plant physiology, molecular biology, environmental science, and conservation perspectives, we aim to foster interdisciplinary dialogue and highlight innovative solutions for enhancing plant resilience. Contributions that explore the interactions between multiple stressors and the role of environmental variables in modulating plant responses are highly encouraged.


We invite original research articles, reviews, and case studies that contribute to a holistic understanding of plant stress responses in terrestrial and aquatic environments. This Special Issue aims to support the development of effective management and remediation strategies that ensure plant and ecosystem resilience in the face of climate change.

    Abstract Nickel (Ni) toxicity significantly impairs plant growth, photosynthesis, and metabolism by inducing oxidative stress. This study evaluates the potential of exogenous Alpha-Ketoglutarate (AKG) in mitigating Ni-induced stress in Peganum harmala L. Seedlings were exposed to 0, 200, 500, and 750 μM NiCl2, with or without AKG supplementation. Under 750 μM Ni stress, dry weight (DW) decreased by 33.7%, tissue water content (TWC) by 39.9%, and chlorophyll a and total chlorophyll levels were reduced by 17% and 15%, respectively. Ni exposure also significantly increased secondary metabolite production, with leaf anthocyanin content rising by 131%, and superoxide dismutase (SOD)… More >

    Abstract Nitrogen (N) is a crucial nutrient vital for the growth and productivity of maize. However, excessive nitrogen application can result in numerous environmental and ecological problems, such as water pollution, biodiversity loss, and greenhouse gas emissions. Therefore, breeding maize hybrids resilient to low nitrogen conditions is crucial for sustainable agriculture, especially under low nitrogen conditions. Consequently, this study aimed to evaluate the combining ability and heterosis of maize lines, recognize promising hybrids, and study gene action controlling key traits under low and recommended N stress conditions. The half-diallel mating design hybridized seven maize inbreds, resulting… More >

    Abstract LONELY GUY (LOG) is a pivotal cytokinin-activating enzyme that plays an important role in plant growth, development, and stress responses. Walnut (Juglans regia), an important woody oilseed species, has not yet undergone systematic identification of its LOG gene family. In this study, we identified 17 JrLOG genes in the walnut genome, which are unevenly distributed across 11 chromosomes. JrLOG gene expansion was primarily driven by gene duplication, along with purifying selection. Members of the JrLOG family were categorized into five groups, each exhibiting analogous gene structures, featured motifs, and conserved domains.

    Abstract Developing high-yield maize hybrids is critical for sustaining maize production, especially in the face of rapid climate changes and the growing global population. Exploring the genetic diversity and combining ability in parental inbreds is needed for developing such high-yielding hybrids. Consequently, this study aimed at evaluating parental genetic diversity employing simple sequence repeats (SSR) markers, estimating effects of general (GCA) and specific (SCA) combining abilities for grain yield and yield contributing characters, identifying high yielding hybrids, and evaluating the association of SCA effects and performance of hybrids with genetic distance. Half-diallel mating scheme was utilized… More >
