Abstract

Abstract: Fungal pathogens are the largest group of plant pathogens in agriculture,which continuously lead to serious yield loss of crops,fruit and vegetables worldwide.At present the control of pathogenic fungi mainly rely on the extensive use of chemical fungicides,which also brings us several concerns such as resistance to fungicides,food safety and ecological environment pollution.Thus,it is urgent to develop a green management strategy for pathogenic fungi in agriculture.Spraying induced gene silencing (SIGS) technology is a new potential bio-control technology in field application by using specific double-stranded RNA or small interfering RNA to control targeted genes of pathogens,which has been successfully applied to control numerous pathogenic fungi.Here,we focused on the advances in the development of SIGS mechanism and its applications on the management of plant pathogenic fungi,which might be helpful to the development of plant pathogenic fungi-targeted bio-pesticides based on SIGS.

Key words: spray induced gene silencing, RNA interference, plant fungal disease, bio-pesticide, crop protection
