GO annotation clusters of differentially expressed genes. Gene Ontology functional enrichment analysis of differentially expressed genes in leaf sheaths and roots. Based on sequence homology, 1,650 genes were distributed among 3 main categories: Cellular Component (16 functional groups, dominated by ‘cell part’), Molecular Function (14 groups, dominated by ‘binding’), and Biological Process (24 groups, dominated by ‘cellular process’).
