Analysis of DNA Methyiation Related on the Interaction between Wheat and Wheat Leaf Rust

doi:10.7668/hbnxb.2008.04.007

Abstract

Abstract: DNA methylation is known to play an important role in the regulation of gene expression in eukaryotes. The wheat near-isogenic line TcLr19 and Thatcher is race-specific resistance and compatible in the interaction with Puccinia triticina respectively. Using methylation -sensitive amplified polymorphism( MSAP)analysis,we compared the patterns of cy- tosine methylation in TcLr19 and Thatcher that had been inoculated with Puccinia triticina,subjected to left untreated. In all,3 554 DNA fragments,each representing a recognition site cleaved by either or both of two isoschizomers,were amplified using 60 pairs of selective primers. A total of 998 sites were found to be one of the methylated. The results suggest that no differences in cytosine methylation exist between seedlings inoculated and those unchallenged.

Key words: DNA methylation, Puccinia triticina, MSAP, Resistance
