a
Gene families from 1 to 8 were all identified from “starch and sucrose metabolism” category according to the KEGG protein database;
b
The numbers under “Unigene no.” column represent the total number of unigenes in each enzyme family identified in the radish taproot transcriptome;
c
The numbers under the “NAU-YH_raw fragments (no.)” column represent the raw fragments in each enzyme family identified in the radish taproot transcriptome;
d
The numbers under “RPKM” columns represent the total values of unigene RPKM in each enzyme families identified in the radish taproot transcriptome.
