Abstract:

Abstract: The potassium ion channel is the important channel protein to absorb potassium from soil for tobacco, can significantly improve the quality and the resistance of tobacco, so transferred potassium ion channel gene is widely used in tobacco, such as making use of vector-mediated transformation and direct DNA uptake transformation for the transferred high absorption and accumulation type potassium ion channel gene. Transferred potassium ion channel gene tobacco markedly increases potassium uptake and stress resistance, and improves the drought resistance of tobacco, cold resistance, disease resistance, salt tolerance, etc. Transferred potassium ion channel and resistance-related genes have become new ways for improving stress resistance of tobacco.
