Proteome and Ubiquitinome Analyses Reveal the Involvement of Ubiquitination in Resistance to Maize Lethal Necrosis.

ABSTRACT: The co-infection of maize chlorotic mottle virus (MCMV) and sugarcane mosaic virus (SCMV) causes maize lethal necrosis (MLN), which seriously affects the yield and quality of maize. Ubiquitination is one of the most important protein post-translational modifications. However, the role of ubiquitination modification in regulating maize resistance to viral infection remains largely unknown. In this study, we found that the ubiquitination levels in SCMV- and/or MCMV-infected maize plants were higher than that in the non-infected maize plants. Ubiquitinome and proteome analyses of the above maize plants revealed that most down-regulated differentially accumulated proteins that possessed up-regulated lysine ubiquitination sites were mainly involved in photosynthesis, fructose and mannose metabo
