主　　题：Maize stalk rot Zmprx5 Transgenic Mutant Disease resistance 

摘      要：Maize(Zea mays L.)stalk rot is a devastating disease worldwide,causing severe yield *** previous studies have focused on the genetic dissection of maize resistance to stalk rot,the mechanisms of resistance remain largely *** used a comparative proteomics approach to identify candidate proteins associated with stalk rot *** analyses revealed 763 proteins differentially accumulated between Fusarium graminearum and mock-inoculated *** them,the antioxidant protein ZmPrx5,which was up-accumulated in diseased plants,was selected for further ***5 transcripts were present in root,stalk,leaf,ear,and reproductive *** expression of ZmPrx5 in three inbred lines increased significantly upon *** ***5 was localized in the *** to control plants,maize plants overexpressing ZmPrx5 showed increased resistance to *** infection,and ZmPrx5 mutant plants were more susceptible than wild-type ***-associated pathways including plant–pathogen interactions,phenylalanine metabolism,and benzoxazinoid and flavonoid biosynthesis were suppressed in ZmPrx5 homozygous mutant plants compared with wild-type *** suggest that ZmPrx5 positively regulates resistance against stalk rot in maize,likely through defense-oriented transcriptome *** results lay a foundation for further research on the roles of Prx5 subfamily proteins in resistance to plant fungal diseases,and provide a potential genetic resource for breeding disease-resistance maize lines.
