Plant defense multigene families: II Evolution of coding sequence and differential expression of PR10 genes in Pisum
While it is not possible to directly the observe evolution of multigene families, the best alternative is to compare orthologous family members among several closely-related species with varying degrees of reproductive isolation. Using RT-PCR we show that in pea (Pisum sativum) each member of the pathogenesis-related PR10 family has a distinct pattern of expression in response to the fungus Fus...
متن کاملProof for the Production of Cutinase by Fusarium solani f. pisi during Penetration into Its Host, Pisum sativum.
Rabbit antibody to cutinase-I, isolated from Fusarium solani f. pisi, was conjugated to ferritin. With this ferritin-conjugated antibody it was shown that germinating spores of this fungus excreted cutinase during the penetration of the host pisum sativum. This result constitutes the most specific and strongest evidence for an enzymic penetration of a plant cuticle by a pathogen during infection.
متن کاملA comparison of the effects of DNA-damaging agents and biotic elicitors on the induction of plant defense genes, nuclear distortion, and cell death.
Pea (Pisum sativum L. cv Alcan) endocarp tissue challenged with an incompatible fungal pathogen, Fusarium solani f. sp. phaseoli or fungal elicitors results in the induction of pathogenesis-related (PR) genes and the accumulation of pisatin, a phytoalexin. Essentially the same response occurs in pea tissue exposed to DNA-specific agents that crosslink or intercalate DNA. In this study, the effe...
متن کاملInduced Acidic chitinase Expression and Scab-Resistant in Wheat Under Field Condition
Fusarium head blight (FHB) caused by Fusarium graminearum is responsible for billions of dollars in agriculture losses. The goal of the present study was evaluation the expression of acidic chitinase, one of PR proteins, in wheat defense response against different FHB induced treatments in 'Falat' as a highly susceptible and 'Sumai3' as a tolerant cultivar. These treatments contained fungi extr...
متن کاملEthylene: Symptom, Not Signal for the Induction of Chitinase and beta-1,3-Glucanase in Pea Pods by Pathogens and Elicitors.
Infection of immature pea pods with Fusarium solani f.sp. phaseoli (a non-pathogen of peas) or f.sp. pisi (a pea pathogen) resulted in induction of chitinase and beta-1,3-glucanase. Within 30 hours, activities of the two enzymes increased 9-fold and 4-fold, respectively. Chitinase and beta-1,3-glucanase were also induced by autoclaved spores of the two F. solani strains and by the known elicito...
