Horticultural Plant Cold Resistance Mechanism under WRKY Transcription Factor and Sugar Interaction

Abstract

Cold stress seriously affects the growth development of plants and crop yield. In order to ensure survival, plants have formed a complex and efficient regulatory network to resist the cold stress or gradually adapt to it. WRKY transcription factors play an important role in plant abiotic stress response. Although exogenous sugar can also improve the resistance of plants to cold stress, the response mechanism of plants to cold stress under the interaction between transcription factors and sugar is still unclear. In this review, the author introduced the damage of cold stress on plants, briefly summarized the mechanism and regulatory network of WRKY transcription factors in response to stress. Moreover, the author also reviewed the response of horticultural plants to cold stress after exogenous sugar and explained the possible cold resistance mechanism of horticultural plants under the interaction between WRKY and sugar, which aimed to provide some reference for the study of the internal molecular mechanism of horticultural plants coping with cold stress.
