Assembly and comparative analysis of the complete mitochondrial of Spodiopogon sagittifolius, an endemic and protective species from Yunnan, China.

ABSTRACT:

Background

Spodiopogon sagittifolius, a C4 plant closely related to cultivated crops, is an edible resource and a Class II nationally protected species in China. Endemic to Yunnan, its populations are declining due to habitat destruction, highlighting its resource and conservation importance. Despite its significance, the molecular phylogenetic relationships and genetic mechanisms of adaptive evolution in the genus Spodiopogon remain poorly understood.

Results

We successfully assembled and annotated the first mitochondrial genome of S. sagittifolius using HiFi sequencing and the PMAT tool. The genome is 500,699 bp in length with a GC content of 43.15%. Synteny and dN/dS analyses revealed structural and functional conservation of mitochondrial genomes in closely related speci
