Assembly and comparative analysis of the complete mitochondrial genome of Suaeda glauca

Abstract Background Suaeda glauca ( S. ) is a halophyte widely distributed in saline and sandy beaches, with strong saline-alkali tolerance. It also admired as landscape plant high development prospects scientific research value. The chloroplast (cp) genome has recently been reported; however, the mitochondria (mt) still unexplored. Results mt of were assembled based on reads from Pacbio Illumina sequencing platforms. circular length 474,330 bp. base composition showed A (28.00%), T (27.93%), C (21.62%), G (22.45%). contains 61 genes, including 27 protein-coding 29 tRNA 5 rRNA genes. sequence repeats, RNA editing, gene migration cp to observed genome. Phylogenetic analysis genomes other 28 taxa reflects an exact evolutionary taxonomic status . Furthermore, investigation characteristics, size, GC contents, organization, repeats gulaca genome, was investigated compared land plants, indicating variation plants. However, subsequently Ka/Ks revealed that most genes had undergone negative selections, reflecting importance those genomes. Conclusions In this study, we reported assembly annotation halophytic model glauca. subsequent provided us comprehensive understanding which might facilitate salt-tolerant species.
