摘　　要：禾本科植物的抗病基因主要通过出生—死亡的过程进化,进化过程中会受到不等交换、转座等因素的影响。在这一理论基础上,建立了描述抗病基因数量变化趋势的随机数学模型,重构抗病基因家族的演化历史,以总结演化规律。Gramineous plant disease resistance genes through evolution process from birth to death, the evolutionary process will be affected by the unequal exchange, transposition and other factors. Based on this theory, this paper establishes a stochastic mathematical model for describing the variation tendency of resistance genes, and the evolution history of the disease resistance gene family, in order to sum up the evolution law.
