Nitric oxide (NO) is a crucial signaling molecule in plants, influencing seed dormancy, germination, and aging. This review highlights NO's beneficial role in seed physiology and quality enhancement.
Area of Science:
- Plant Physiology
- Molecular Biology
- Biochemistry
Background:
- Nitric oxide (NO) is recognized as a vital gasotransmitter in plants.
- NO is endogenously produced and influences plant physiology throughout all life stages.
- Its role as a signaling molecule in conjunction with phytohormones is increasingly studied.
Purpose of the Study:
- To review the current knowledge on nitric oxide's role in seed physiology.
- To summarize NO's impact on seed dormancy, germination, and aging.
- To highlight NO's application in seed pretreatment for enhanced quality.
Main Methods:
- Literature review of existing research on nitric oxide in plants.
- Analysis of NO's signaling pathways and interactions with other molecules.
- Synthesis of findings on NO's effects across different seed developmental stages.
Main Results:
- Nitric oxide significantly influences seed dormancy, germination, and aging processes.
- NO acts as a key regulatory molecule with predominantly beneficial effects on seed physiology.
- Seed pretreatment techniques involving NO can enhance overall seed quality.
Conclusions:
- Nitric oxide is a critical modulator of seed physiology from dormancy to senescence.
- Understanding NO's mechanisms offers potential for improving seed performance and crop yield.
- Further research into NO signaling networks will advance plant science and agricultural applications.
