Salinity tolerance mechanisms and their breeding implications
Summary
Researchers reviewed cutting-edge plant breeding tools — including CRISPR gene editing, genomic mapping, and hyperspectral imaging — that help scientists develop crop varieties better able to tolerate salty soils, which is increasingly important as climate change threatens agricultural productivity.
Novel emerging approaches of plant breeding and biotechnologies such as genome-wide association studies, mutational breeding, marker-assisted breeding, double haploid production, hyperspectral imaging, and CRISPR/Cas serve as engineering tools for dissecting the in-depth physiological mechanisms. These techniques have well-established implications to understand plants' adaptions to develop more tolerant varieties and lower the energy expenditure in response to stress and, constitutively fulfill the void that would have led to growth resistance and yield penalty.

Review of Crop Response to Soil Salinity Stress: Possible Approaches from Leaching to Nano-Management
This review covers approaches to managing soil salinity, a problem that threatens global food production, using methods ranging from traditional leaching to newer nanotechnology-based solutions. While not directly about microplastics, soil health is connected to microplastic contamination because plastic mulch films used in agriculture are a major source of microplastic pollution in farmland soils.
Climate Change—The Rise of Climate-Resilient Crops
This review discusses efforts to breed climate-resilient crops that can withstand extreme weather events like droughts, floods, and heat waves caused by climate change. While not about microplastics, the research is relevant because microplastic contamination in agricultural soil adds another stress factor that crops must cope with. As both climate change and plastic pollution worsen, understanding how plants respond to combined environmental stresses becomes increasingly important for food security.
Exploring the nano-wonders: unveiling the role of Nanoparticles in enhancing salinity and drought tolerance in plants
This review explores how nanoparticles can help plants survive drought and high-salt conditions by protecting cell membranes, boosting photosynthesis, and strengthening antioxidant defenses. While promising for agriculture, the effects of nanoparticles vary depending on their size, shape, and concentration, and their potential toxicity to plants needs further study.
Current methods and future needs for visible and non-visible detection of plant stress responses
This review examines current and emerging methods for detecting plant stress responses, from molecular-level techniques like genomics and metabolomics to whole-plant remote sensing approaches. Researchers highlight that climate change is creating more complex combinations of stresses that no single detection technology can fully capture. The study calls for integrative multi-omic approaches that connect cellular changes to visible plant-level symptoms for more effective agricultural stress management.
Relationships between soil salinity and economic dynamics: Main highlights from literature
This bibliometric review of soil salinity research found that most studies focus on agricultural strategies for managing salinity, food security, desertification, and climate change impacts, while direct assessments of socioeconomic impacts from soil salinity and broader sustainability dimensions have received comparatively little attention.
