a
: The classification was based on the RiceCyc database at the GRAMENE Web site (http://www.gramene.org/pathway/).
b
: PWY-2881, PWY-2901, and PWY-2902 share the same genes in the respective pathways.
c
: The ratio was calculated as the number of CDS-AE loci/total number of loci.
d
: Significances of difference were examined between the CDS-AE proportion in genes in the respective pathway and that of all genes associated with metabolic pathways by the chi-squared test. High (Low) represents that the cloning efficiency of genes for a metabolic pathway was higher (lower) than the collection efficiency for all genes associated with metabolic pathways.
