Special Issue Information

Dear Colleagues,

In recent decades, climate change and environmental degradation have intensified the frequency and severity of the abiotic and biotic stresses affecting crop systems worldwide. Understanding how crops respond and adapt to these environmental challenges is a central question in plant science and agricultural innovation. Historically, research has focused on individual stressors, but current efforts are shifting toward integrated approaches that consider complex and simultaneous stress interactions.

This Special Issue aims to highlight recent advances in our understanding of the physiological, molecular, and genetic responses of crops to various environmental stresses—including drought, salinity, heat, cold, flooding, and pest pressures. Emphasis will be placed on interdisciplinary research that links fundamental mechanisms with applied strategies to improve crop resilience and productivity.

We invite contributions that explore novel insights into plant signaling pathways, stress-responsive gene networks, microbiome interactions, phenotyping technologies, and breeding or biotechnological approaches aimed at enhancing stress tolerance. Studies that include omics tools, systems biology, modeling, or field-based validations are particularly welcome.

Original research articles, reviews, and opinion pieces that provide a forward-looking perspective on the adaptation of crops to a changing environment will form the backbone of this Special Issue. Our goal is to provide a platform for cutting-edge research that bridges knowledge gaps and supports the development of sustainable and resilient agricultural systems.

Abstract
Nano-titanium dioxide (nano-TiO2) can alleviate oxidative damage in plants subjected to abiotic stress, interfere with related gene expression, and change metabolite content. Polylactic acid (PLA) microplastics can inhibit plant growth, induce oxidative stress in plant cells, and alter the biophysical properties [...] Read more.
Nano-titanium dioxide (nano-TiO2) can alleviate oxidative damage in plants subjected to abiotic stress, interfere with related gene expression, and change metabolite content. Polylactic acid (PLA) microplastics can inhibit plant growth, induce oxidative stress in plant cells, and alter the biophysical properties of rhizosphere soil. In this study, untargeted metabolomics (LC-MS) and RNA-seq sequencing were performed on radish root cells exposed to nano-TiO2 and PLA. The results showed that nano-TiO2 alleviated the growth inhibition of radish roots induced by PLA. Nano-TiO2 alleviated PLA-induced oxidative stress, and the activities of SOD and POD were decreased by 28.6% and 36.0%, respectively. A total of 1673 differentially expressed genes (DEGs, 844 upregulated genes, and 829 downregulated genes) were detected by transcriptome analysis. Metabolomics analysis showed that 5041 differential metabolites were involved; they mainly include terpenoids, fatty acids, alkaloids, shikimic acid, and phenylpropionic acid. Among them, phenylpropanoid biosynthesis as well as flavone and flavonol biosynthesis were the key metabolic pathways. This study demonstrates that nano-TiO2 mitigates PLA phytotoxicity in radish via transcriptional and metabolic reprogramming of phenylpropanoid biosynthesis. These findings provide important references for enhancing crop resilience against pollutants and underscore the need for ecological risk assessment of co-existing novel pollutants in agriculture.
