Study Of Host-Fungus Interactions Between Soybean And Phakopsora Pachyrhizi Using Proteomics, Sunjung Park

LSU Doctoral Dissertations

Asian soybean rust, caused by Phakopsora pachyrhizi, is an emerging disease in the continental U. S. and resistant commercial varieties have not been reported. In an effort to understand the interactions during rust infection of soybean, protein profile changes were examined over a 14-day period in soybean leaves of one susceptible commercial line (Pioneer 93M60) with or without soybean rust inoculation using proteomics in this study. Forty protein spots differentially expressed after rust inoculation were identified and fourteen of them were recovered and sequenced. These included proteins involved in plant defense, stress, metabolism, and other biological processes. During the time-course …
