In the process of growth and development of sugar crops,drought and water scarcity have a certain impact on their normal growth.Under drought conditions,sugar crops present corresponding changes in morphological,physiological and biochemical characteristics.In addition,drought stress induces the expression of certain genes,which alleviate the damage on sugar crops.This paper provides an overview of the responses of sugar crops to drought stress in terms of morphological,physiological and biochemical properties,as well as the related research progress on drought tolerant regulatory genes.According to the literature review,the main gene types that regulate drought stress in sugar crops are as follows:Calcium-dependent protein kinase(CDPK)gene,mitogen-activated protein kinase(MAPK)gene,AVP1 gene,and transcription factors such as DREB,NAC and WRKY genes.It can serve as a reference for improving the drought tolerance of sugar crops.
