| Abstract: | Cold stress can inhibit plant growth and development. Although plants can effectively sense the occurrence of cold stress and respond to it, the frost resistance of plants alone is not enough to resist the damage to plants caused by cold stress. Cold stress causes abnormal growth of plant roots and reduces water absorption, changes leaf structure and causes damage to chloroplasts, affects plant flowering and reproduction and inhibits seed germination.The main strategies to enhance the ability of plants to resist cold stress are the use of cold stress regulators （hormones and growth regulators）, inoculation of symbiotic microorganisms （Arbuscular mycorrhizal fungi, Bacillus amyloliquefaciens, Azospirillumbrasilense,etc.） and genetic engineering. How cold stress affects plant cell metabolism is still inconclusive, and the molecular mechanism that symbiotic microorganisms enhance plant resistance to cold stress remains unclear. Therefore, exploring the metabolic pathways of plant cells and the molecular mechanism of plant cells responding to cold stress may become research hotspots in this field in the future.
