What is Ecological significance of Candidatus ARS69 and Gemmatimonadota in the Arctic glacier foreland ecosystems about?

## Abstract The __Gemmatimonadota__ phylum has been widely detected in diverse natural environments, yet their specific ecological roles in many habitats remain poorly investigated. Similarly, the __Candidatus ARS69__ phylum has been identified only in a few habitats, and literature on their metabolic functions is relatively scarce. In the present study, we investigated the ecological significance of phyla __Ca. ARS69__ and __Gemmatimonadota__ in the Arctic glacier foreland (GF) ecosystems through genome-resolved metagenomics. We have reconstructed the first high-quality metagenome-assembled genome (MAG) belonging to __Ca. ARS69__ and 12 other MAGs belonging to phylum __Gemmatimonadota__ from the three different Arctic GF samples. We further elucidated these two groups phylogenetic lineage and their metabolic function through phylogenomic and pangenomic analysis. The analysis showed that all the reconstructed MAGs potentially belonged to novel species. The MAGs belonged to __Ca. ARS69__ consist about 8296 gene clusters, of which only about 8% of single-copy core genes (__n__ = 980) were shared among them. The study also revealed the potential ecological role of __Ca. ARS69__ is ass
