|April 3, 2015
Summary
This study computationally analyzes hypothetical GH10 endo-beta-xylanases in Planctomycetes bacteria. Findings suggest these enzymes are vertically transferred and functionally important in heterotrophic Planctomycetes.
Area of Science:
- Microbiology
- Enzymology
- Bioinformatics
Context:
- Planctomycetes are a bacterial phylum with limited functional characterization.
- GH10 endo-beta-xylanases are enzymes involved in xylan degradation.
- These enzymes are present across various heterotrophic Planctomycetes genomes.
Purpose:
- To computationally analyze hypothetical GH10 endo-beta-xylanases in Planctomycetes.
- To determine the phylogenetic relationship and gene transfer patterns of these enzymes.
- To infer the functional importance of endo-beta-xylanases in Planctomycetes.
Summary:
- Computational analysis revealed a distinct phylogenetic cluster of GH10 endo-beta-xylanases in Planctomycetes.
- Nucleotide sequences for endo-beta-xylanase genes were determined for five strains of the Isosphaera-Singulisphaera group.
- Congruence between 16S rRNA gene trees and endo-beta-xylanase amino acid sequences suggests vertical gene transfer.
Impact:
- Suggests vertical transfer and functional importance of endo-beta-xylanase genes in Planctomycetes.
- Provides insights into the poorly characterized functional capabilities of this bacterial phylum.
- Highlights the role of specific enzymes in bacterial evolution and adaptation.

Planctomycetes are a group of morphologically distinct bacteria predominantly classified into two orders: Planctomycetales and Brocadiales. These gram-negative bacteria exhibit unique features, including division by budding and the presence of stalks or appendages. Their cells are often found in rosette arrangements, and they are notable for possessing an S-layer in their cell envelope, which is relatively uncommon among bacteria. Additionally, Planctomycetes frequently exhibit intracellular...

2.1K
Zygomycota, previously classified as a distinct fungal group, are primarily terrestrial, saprophytic molds that play a crucial role as decomposers. Recent phylogenetic studies have revealed that these fungi are now divided into two major clades — Mucoromycota, which includes many symbiotic species, and Zoopagomycota, which primarily consists of parasitic and pathogenic fungi. These groups exhibit distinct ecological roles and reproductive strategies while sharing key structural and...

Understanding the evolutionary relationships among microorganisms is fundamental to microbial ecology and taxonomy. Phylogenetic trees are essential tools for inferring these relationships, relying primarily on comparative analyses of molecular sequences such as DNA, RNA, or proteins. In microbial studies, these trees typically depict the evolutionary paths of diverse bacterial and archaeal species by mapping genetic differences accumulated over time.Phylogenetic trees are composed of tips,...

01:23Phylogeny
64.8K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

7.3K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.
