Abstract: Cold resistance or freezing tolerance is used to represent the ability of plants to adapt to and withstand freezing temperatures. It is a complex, multigenetic trait, and its research has a wealth of history. Recent studies provide an important clue for plants responding to low temperature and acquiring cold resistance. In this paper, advances in ice nuclation and its transmission, deep supercooling and vitrification, physiology and genetic regulation of cold acclimation, molecular biology of cold acclimation and genetic engineering approaches were summarized in woody plants, which provide references for improving cold hardiness in economically important crops while still maintaining high yield.

Key words: woody plant, cold resistance, low temperature response gene

摘要: 抗寒性是植物适应和忍耐低温胁迫的能力,是复杂的多基因特征,其研究历史悠久。近些年的研究为理解植物如何响应外界低温并获得抗寒性提供了重要线索。本文概述了低温下木本植物冰核及其传播、深度过冷却与玻璃化形成、低温锻炼的生理学与遗传调控、低温锻炼的分子生物学与遗传工程等方面的进展,以期为人们在维持重要作物高产的同时提高其抗寒性提供参考。
