摘　　要：Crop diseases cause enormous yield losses and threaten global food security.Deployment of resistant cultivars can effectively control the disease and to minimize crop losses.However,high level of genetic immunity to disease was often accompanied by an undesired reduction in crop growth and yield.Recently,literatures have been rapidly emerged in understanding the mechanism of disease resistance and development genes in crop plants.To determine how and why the costs and the likely benefit of resistance genes caused in crop varieties,we re-summarized the present knowledge about the crosstalk between plant development and disease resistance caused by those genes that function as plasma membrane residents,MAPK cassette,nuclear envelope(NE)channels components and pleiotropic regulators.Considering the growth-defense tradeoffs on the basis of current advances,finally,we try to understand and suggest that a reasonable balancing strategies based on the interplay between immunity with growth should be considered to enhance immunity capacity without yield penalty in future crop breeding.
