  1. 1: Amino acids displaying differences in abundance patterns between SSPs and non-SSPs are shown in bold face type. Aspartic acid ranked top only in the non-SSPs of Halobacterium sp NRC1 (GC 65.9%).
  2. 2: Arginine ranked top in the non-SSPs of Xanthomonas oryzae pv oryzae KACC10331 (GC 63.7%) only.
