A comparative analysis of nine Araceae species revealed significant variation in mitochondrial genome architecture. Key findings include:

In the context of mitochondrial genomics, represents the maximum cumulative length of dispersed repeats identified in a comparative study of Araceae (Aroid) mitochondrial genomes. Specifically, this total was found in the species Pinellia ternata , which possesses the largest genome in the group.

Below is a draft write-up summarizing these findings for a technical report or study summary: 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.

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.

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).

Sizes across the nine species vary approximately five-fold, ranging from 177,872 bp ( W. australiana ) to 876,608 bp ( P. ternata ). Below is a draft write-up summarizing these findings
