本发明涉及基因工程领域，具体地说，涉及棉花基因GthICE2在植物耐干旱和冷胁迫方面的应用。本发明通过转基因技术获得了过表达GthICE2基因的拟南芥纯合系，干旱和冷处理后，发现其对干旱和冷胁迫的耐受性显著提高。本发明在提高棉花抗旱耐冷的育种和研究中具有重要的意义，可应用于抗选育抗逆棉花品种。 The invention relates to the field of gene engineering, in particular to application of a cotton gene GthICE2 in drought resistance and cold stress resistance of plants. According to the invention, an arabidopsis thaliana homozygous line over-expressing the GthICE2 gene is obtained through a transgenic technology, and after drought and cold treatment, the tolerance of the arabidopsis thaliana homozygous line to drought and cold stress is obviously improved. The invention has important significance in breeding and research for improving drought resistance and cold resistance of cotton, and can be applied to breeding of stress-resistant cotton varieties.
