Table 4 KEGG pathway enrichment in initiating storage roots and fibrous roots, relative to the rest of the root transcriptome database

From: Transcriptional profiling of sweetpotato (Ipomoea batatas) roots indicates down-regulation of lignin biosynthesis and up-regulation of starch biosynthesis at an early stage of storage root formation
