Abstract:

Potassium resources is lack in china and the potassium deficiency is common in cotton areas.Potassium is one of the most needed elements in cotton.Premature,yield reduction and red leaf blight can be caused by potassium deficiency.The research of low potassium resistant cotton is a matter as great urgency.Low potassium tolerant variety can be selected by conventional breeding.The potassium uptake genes have laid a basis for genetic engineering breeding,so the transgenic technology has been attractive.The im...

Key words: potassium, gene clone, genetic improvement;
