The invention provides a plant low-temperature induced expression promoter Poscold10 and application thereof. The invention further provides an expression cassette, a plant expression vector, host bacteria and a transformant containing the promoter. Specifically, the plant low-temperature induced expression promoter Poscold10 is applied in plant genetic engineering. The promoter can specifically drive the high-intensity expression of foreign genes in plants under low temperature conditions. By connecting the promoter to a gene to be expressed and transferred into a plant using a vector, the expression of the foreign gene in various parts of the plant under low temperature conditions can be driven. 本发明提供一种植物低温诱导表达启动子Poscold10及其应用。本发明还提供了含有该启动子的表达盒、植物表达载体、宿主菌和转化子。具体而言，本发明将上述启动子应用在植物基因工程中。本发明提供的启动子能够特异地驱动外源基因在低温条件下在植物中高强度表达。通过将本发明的启动子连接到待表达的基因并利用载体转入到植物植株中，能够在低温条件下驱动外源基因在植物的各个部位中表达。
