As we all know, global warming has begun to affect yield and quality of crops, so directly enhancing the capacity of heat resistance in plant is an effective solution to this global problem. In this paper, authors summarized some successful approaches to enhance the capacity of heat tolerance in plant based on a large number of research progresses on transgenic pathway, as well as proposed new solution to enhance the capacity of heat tolerance in plant by using genetic engineering methods to reduce the quantities of heat stress proteins that lost their functions.
