Pathogenesis and Functional Genomics of Rice False Smut Ustilaginoidea virens and Genetic Mechanism of Immune Response in Rice
Rice false smut(RFS)has become one of the most major rice diseases in China.RFS not only decrease the yield and quality of rice,but also threatens the health and safety of human and livestock.While some progress has been made in the study of RFS and its interaction with rice,there are limitations in the mode of infection,pathogenic mechanism,evaluation criteria of resistance in rice,mining of resistance genes,and prevention and control measures,etc.In order to enhance the understanding of RFS,we reviewed the history and occurrence of RFS,biological characteristics of Ustilaginoidea virens,infection characteristics of Ustilaginoidea virens,genetic rule and gene identification of resistance to RFS,genetic mechanism of resistance,resistance identification techniques and influencing factors of RFS occurrence.Meanwhile,preliminarily discussed the model of host immune response triggered by Ustilaginoidea virens.Finally,we provided some analyses and prospects on how to further carry out the related research,in order to develop rice disease resistance materials for breeding programs.
