Chloroplasts are key organelles in the management of oxygen in algae and plants and are therefore crucial for all living beings that consume oxygen.
Chloroplasts typically contain a circular DNA molecule with nucleus-independent replication and heredity.
Using “palindrome analyser” we performed complete analyses of short inverted repeats (S-IRs) in all chloroplast DNAs (cpDNAs) available from the NCBI genome database.
Our results provide basic parameters of cpDNAs including comparative information on localization, frequency, and differences in S-IR presence.
In a total of 2,565 cpDNA sequences available, the average frequency of S-IRs in cpDNA genomes is 45 S-IRs/per kbp, significantly higher than that found in mitochondrial DNA sequences.
The frequency of S-IRs in cpDNAs generally decreased with S-IR length, but not for S-IRs 15, 22, 24, or 27 bp long, which are significantly more abundant than S-IRs with other lengths.
These results point to the importance of specific S-IRs in cpDNA genomes.
Moreover, comparison by Levenshtein distance of S-IR similarities showed that a limited number of S-IR sequences are shared in the majority of cpDNAs.
S-IRs are not located randomly in cpDNAs, but are length-dependently enriched in specific locations, including the repeat region, stem, introns, and tRNA regions.
The highest enrichment was found for 12 bp and longer S-IRs in the stem-loop region followed by 12 bp and longer S-IRs located before the repeat region.
On the other hand, S-IRs are relatively rare in rRNA sequences and around introns.
These data show nonrandom and conserved arrangements of S-IRs in chloroplast genomes.
