Frontiers

Plant-specific upregulated DEGs under low-temperature stress play a more critical role in determining plant cold resistance than downregulated DEGs, and a higher percentage of upregulated genes increases the resistance of plants to cold (Zhang, 2015).

Phosphate fertilizers improve plant cold resistance primarily by enhancing physiological activities and metabolic levels, thereby strengthening their ability to withstand freezing conditions. The mechanisms are detailed below:

1. Enhanced Root System Vitality Phosphorus, an essential nutrient in phosphate fertilizers, promotes root growth and development. A robust root system enables plants to absorb water and nutrients more efficiently from the soil, which is critical for improving cold tolerance.

2. Improved Photosynthetic Efficiency Phosphorus facilitates chlorophyll synthesis in leaves, boosting photosynthesis—the process by which plants convert solar energy into chemical energy. Enhanced energy production helps plants better endure harsh, cold environments.

3. Promoted Protein Synthesis Phosphorus stimulates protein production, which strengthens cellular structures and stabilizes cell membranes. This reinforces cells against damage caused by temperature fluctuations.

4. Increased Antioxidant Capacity Phosphorus activates antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT), enabling plants to neutralize harmful free radicals. This reduces oxidative stress and protects tissues during cold stress.

5. Regulated Hormone Balance Phosphorus influences the synthesis of hormones like gibberellins, auxins, and ethylene, which regulate growth and metabolic processes. A balanced hormonal environment optimizes cold adaptability.

6. Elevated Antifreeze Protein Levels Phosphorus increases the production of antifreeze proteins, which safeguard cell membranes from ice crystal formation and physical damage at low temperatures.

7. Improved Osmoregulation Phosphorus boosts the accumulation of osmoprotectants like proline and betaine. These compounds adjust cellular osmosis, mitigating stress from freezing or salt-alkaline conditions.

8. Strengthened Disease Resistance Phosphorus enhances the synthesis of antimicrobial compounds (e.g., phenolics and flavonoids), reducing pathogen-induced susceptibility. Healthier plants are better equipped to survive cold snaps.

Phosphate fertilizers enhance cold resistance through multiple pathways: strengthening roots, boosting photosynthesis, synthesizing proteins, activating antioxidants, balancing hormones, increasing antifreeze proteins, regulating osmosis, and improving disease resilience. Rational application of phosphate fertilizers is thus vital for improving plant hardiness in cold climates.
