摘要
Loss of resistance to fast-adapted pathogens urgently calls for a sustainable and broad-spectrum strategy to meet the requirement of crop yield and safety for the increasing world population.Pyramidization of resistance genes,such as nucleotide-binding leucine-rich repeat proteins,from diverse cultivars,landraces,and domesticated or wild germplasm accessions offers the most direct practice for this purpose.Nevertheless,the facts of a narrow resistance spectrum and limited number or even shortage of such resistance genes to many specific pathogens leave an immediate question to be resolved in such a situation.In light of the evidence that all compatible pathogens trigger a conserved and wide range of host genes,namely susceptibility genes for their proliferation,management of those genes are of equal importance and promising for improvement in crop disease resistance(Zaidi et al.,2018).
