Expression level (TGR, red-blue heat map) of genes potentially involved in GAX backbone decoration in maize root and relative levels of the corresponding proteins (averaged and normalized total spectral counts22, red-green heat map. Heat map color coding is applied separately to each gene subgroup. The genes co-expressed with maize primary cell wall CesAs are labelled in blue, and genes co-expressed with secondary cell wall CesAs are labelled in red. Annotations are based on the study by Penning et al.18, and are obtained by matching the RefGen_v3 and RefGen_v4 gene models. Cap—root cap, Mer—meristem, eElong—early elongation zone, Elong—zone of active elongation, lElong—zone of late elongation before root hair initiation, and RH—root hair zone. No data, i.e., no corresponding peptides were detected in any of the studied root samples22.
