摘要

Abstract

The order Watanabeales (Trebouxiophyceae

Chlorophyta) was established in 2021 to include unicellular coccoid green algae but its species diversity must be further explored. The genus

Jaagichlorella

(Watanabeales) currently encompasses nine species and two varieties. In this study

strain FACHB-3637 was isolated from tree bark in Yunnan Province

China. A polyphasic approach combining molecular phylogenetic analyses and morphology was used to investigate the strain. The results reveal that strain FACHB-3637 represents a new lineage within the genus

Jaagichlorella

and we propose it as a new species

Jaagichlorella

menglunensis

sp. nov. Additionally

we report the complete mitochondrial genome of this new species and present a comparative analysis of the mitochondrial genomes in the genus

Jaagichlorella

. The analysis reveals substantial differences in mitochondrial genome size

structure

and gene composition among

menglunensis

hainangensis

and

roystonensis
