Dispersed repeats were categorized by length into four classes (Class I: 50–100 bp; Class II: 100–500 bp; Class III: 500–5000 bp; and Class IV: >5000 bp).
The high frequency and large cumulative length of repeats (reaching up to 122,573 bp) in certain species like P. ternata are primary drivers of mitochondrial genome expansion within the Araceae family. Comparative Analysis of Araceae Mitochondrial Genomes - PMC 122573
The species P. ternata is unique in this group for possessing Class IV repeats (those larger than 5,000 bp), which account for approximately 5.5% of its total mitogenome length. Dispersed repeats were categorized by length into four
