A great of loss in agriculture and forestry was caused by plant diseases all over the world every year,and there is no satisfactory traditional method to protect the diseases.Considerable progress in molecular biology of plant disease resistant genes has been made in recent years especially in the study on cloning of desease resistant genes by means of functional cloning,positional cloning,sequence cloning and phenotype cloning.Moreover,there are lots of achievements made in the researches of gene engineering for plant disease resistance in the past few years.In this paper,the characteristics,mechanism and prospects of the strategies on the cloning of disease resistant genes were reviewed,and rapid progress has been made in the study of disease resistance in the forest trees.Meanwhile the problems existed were discussed and the strategies for the possible solution were also pointed out in this paper.
