Gene ontology (GO) enrichment analyses of differential hub genes. A Root cap and meristem (CM) after 6 h (CM6/MElavenderblush1). B CM after 48 h (CM48/MEdarkolivegreen). C Elongation zone (EZ) after 6 h (EZ6/MElightpink4). D EZ after 24 h (EZ24/MElightpink2). E EZ after 48 h (EZ48/MElightyellow). F Differentiation zone (DZ) after 48 h (DZ48/darkgoldenrod4). Differential hub genes are represented by grey dots and connected to enriched biological processes (dark grey diamond), and /or enriched molecular functions (light grey hexagon). GO terms associated with similar functions are circled and labeled accordingly
