Application of Camellia oleifera CoBBX22 protein in regulation and control of plant drought tolerance

The invention belongs to the technical field of plant molecular biology, and particularly relates to application of oil-tea camellia CoBBX22 protein in regulation and control of plant drought tolerance, and the amino acid sequence of the oil-tea camellia CoBBX22 protein is shown as SEQ ID NO.1. Research finds that overexpression of the CoBBX22 gene in arabidopsis thaliana can enhance the sensitivity of arabidopsis thaliana to drought, the result provides a related basis for further understanding of camellia oleifera BBX gene family functions, and reference and gene resources are provided for cultivation of new camellia oleifera varieties through a molecular breeding means in the later period. 本发明属于植物分子生物学技术领域，具体涉及油茶CoBBX22蛋白在调控植物耐旱性中的应用，所述油茶CoBBX22蛋白的氨基酸序列如SEQ ID NO.1所示。本发明研究发现，在拟南芥中过表达CoBBX22基因可增强其对干旱的敏感性，该结果为进一步了解油茶BBX基因家族功能提供了相关依据，为后期通过分子育种手段培育油茶新品种提供参考及基因资源。
