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