Genomic and Functional Analysis of Carbohydrate Esterases in the Maize Pathogen <i>Exserohilum rostratum</i>.

ABSTRACT: Exserohilum rostratum is a causal agent of severe maize leaf spot, posing a threat to maize production. Carbohydrate esterase (CE) can catalyze the removal of acyl modifications from plant cell wall polysaccharides, thereby promoting polysaccharide hydrolysis. A total of 87 CE genes were identified in the E. rostratum ER1 genome. In this study, we conducted a comprehensive analysis of the E. rostratum CE (ErCE) genes, including physicochemical properties, structural features, promoter cis-acting regulatory elements, and functional analysis. Subcellular localization analysis revealed that more than half of ErCEs were located extracellular. ErCEs contain abundant conserved domains, indicating functional diversity of these proteins. The promoter region of
