Fig. 5

The interconversion between amino sugar and nucleotide sugar in P. purpureum. The red plus sign indicates upregulation, the blue minus sign indicates downregulation, and the black sign indicates no significant difference. The front and back positions indicate the differential expression at day 5 and day 15, respectively.
