Proteomics Analysis of Lily Blight Disease-resistant Clones
To elucidate the key proteins related to disease-resistance of lily induced by Fusarium oxysporum f.sp.lilii,protein two-dimensional gel electrophoresis technology was used to analyze profiles of the disease-resistant and susceptible clones after inoculation of Fusarium oxysporum f.sp.lilii for 0,24,48 and 72 h.Tweenty-five differentially expressed proteins were successfully identified,including 10 differentially expressed proteins identified as unknown function proteins.The rest of the 15 differentially expressed proteins can be categorized into 4 classes according to the function,namely the defense reaction,photosynthesis,carbohydrate and energy metabolism,and heat shock-related proteins.The disease related proteins participated in the defense reaction including presumption of disease-resistant protein RPS2,putative late blight resistant protein homolog R1 C-3,peroxidase Q,ascorbate peroxidase and NBS-LRR-like protein,which may play key roles in the resistance against lily blight.
