Heatmap analysis of DEGs and DAPs based on transcriptomic and proteomic, which are associated with cell wall metabolic processes. Red indicates significantly upregulated proteins, and blue indicates significantly downregulated proteins. White indicates proteins with no significant changes. a, g Heat map of phenylpropanoid biosynthesis-associated gene and protein expression. b, h Heat map of galactose metabolism-associated gene and protein expression. c, i Heat map of amino sugar and nucleotide sugar metabolism-associated gene and protein expression. d, j Heat map of starch and sucrose metabolism-associated protein expression. e, k Pentose and glucuronate interconversions metabolism-associated gene and protein expression. f Cell wall-related transcription factor. l Cell wall metabolism-associated protein expression
