In this study, what had been used inculding CBF1 and CBF3 of CBF family, its downstream COR15a gene , regulating element CRT/DRE in promoter of COR15a gene, Cloning CBF1 and CBF3 from Arabidopsis thaliana, and Cloning ApCOR15a gene from Arabis pumila of xinjiang. On the basis of plasmid pBI121,being used CaMV35S promoter and SAR iductivity promoter synthesized by PCR, six plant expression vectors had been constructed: pCB111, pCB111-1, pCB112,pCB112-1,pCB113, pCB113-1, and then transformed to Agrobacterium GV3101 by electics.

本研究选用了CaMV35S组成型启动子和人工合成的由水杨酸诱导的启动子SAR、拟南芥CBFs家族中的CBF1和CBF3、新疆小拟南芥COR15a基因及其CRT/DRE顺式作用元件构建了不同组合的六个植物表达载体：pCB111、pCB111-1、pCB112、pCB112-1、pCB113和pCB113-1，并采用农杆菌介导的叶盘转化法转化烟草，获得了大量的抗性植株。

Considered the inside and outside contour line was Archimedes spiral in the cold rolling, the forming law of rectangular cross sectional rings has been studied.
