Summary
This summary is machine-generated.This study explores chloroplast genome diversity in the moss genus *Tortula*, revealing non-monophyletic relationships and identifying key genetic markers for future bryophyte phylogenomics.
Area Of Science
- Plant Biology
- Genomics
- Evolutionary Biology
Background
- The Pottiaceae family, a diverse bryophyte group, has largely unexplored chloroplast genome diversity.
- Understanding this diversity is crucial for resolving evolutionary relationships within the family.
Purpose Of The Study
- To investigate chloroplast genome variation within the *Tortula* moss genus.
- To identify evolutionary informative loci for phylogenetic studies in Pottiaceae.
Main Methods
- Comparative analysis of nine *Tortula* species' chloroplast genomes using next-generation sequencing (NGS) data.
- Assembly and annotation of high-quality chloroplast genomes.
- Phyloplastomic analysis using maximum likelihood.
Main Results
- Conserved quadripartite chloroplast genome structures were observed across species.
- Adenine-thymine (AT)-rich dinucleotide repeats were the most common simple sequence repeats (SSRs).
- Phylogenetic analysis indicated that *Tortula* section *Tortula* is not monophyletic, with two major clades identified.
Conclusions
- The study provides novel insights into chloroplast genome evolution in *Tortula*.
- Candidate loci were identified for future bryophyte phylogenomic studies.
- This research enhances understanding of plastome-based studies in Pottiaceae.

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...
Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
Archaea, one of the three domains of life, exhibit remarkable diversity and adaptability, thriving in both extreme and moderate environments. Historically, most identified archaea have been classified into two major phyla: Euryarchaeota and Crenarchaeota. However, recent molecular studies have expanded this classification to include three additional phyla: Thaumarchaeota, Nanoarchaeota, and Korarchaeota, each exhibiting unique characteristics and ecological roles.Thaumarchaeota: Mesophiles...
From Water to Land
Kingdom Plantae first appeared about 410 million years ago as green algae transitioned from water to land. This land was a relatively uncolonized environment with ample resources. Terrestrial environments also offered more light and carbon dioxide, required by plants to grow and survive.
However, the stark differences between land and sea posed a formidable challenge to early colonizing species prompting many new adaptations that have resulted in the wide variety of plant...
