NORG length varies, but number and distribution are relatively constant across Oryza genomes. (A) NORG number per chromosome in each accession. (B) Correlation of NORG number with the chromosome size. (C) Total length of NORGs per chromosome in each accession. The total length of all NORGs from each chromosome was summed. (D) Sum of NORG lengths per chromosome in each accession correlated to chromosome size. (E) ONG length distribution. The x-axis indicates the length range of ONGs, with 200 indicating a length range of 100–200 bp, 300 indicating a length range of 200–300 bp, and so on. (F) Chromosomal distribution of ONGs in 16 O. sativa accessions. Chromosome heatmaps in the left and right represent the length and frequency of ONGs, respectively. A total of 1456 ONGs in 16 O. sativa assemblies were mapped to the O. sativa ssp. japonica cv. Nipponbare genome IRGSP-1.0.
