Phylogeny of Prokaryotes and Chloroplasts Revealed by a Simple Composition Approach on All Protein Sequences from Complete Genomes Without Sequence Alignment [PDF]

open access: yes, 2005
The complete genomes of living organisms have provided much information on their phylogenetic relationships. Similarly, the complete genomes of chloroplasts have helped to resolve the evolution of this organelle in photosynthetic eukaryotes.

SigTree: A Microbial Community Analysis Tool to Identify and Visualize Significantly Responsive Branches in a Phylogenetic Tree. [PDF]

open access: yes, 2017
Microbial community analysis experiments to assess the effect of a treatment intervention (or environmental change) on the relative abundance levels of multiple related microbial species (or operational taxonomic units) simultaneously using high ...

On the Ancestral Compatibility of Two Phylogenetic Trees with Nested Taxa [PDF]

open access: yes, 2005
Compatibility of phylogenetic trees is the most important concept underlying widely-used methods for assessing the agreement of different phylogenetic trees with overlapping taxa and combining them into common supertrees to reveal the tree of life.

Functional traits mediate individualistic species‐environment distributions at broad spatial scales while fine‐scale species associations remain unpredictable

open access: yesAmerican Journal of Botany, Volume 109, Issue 12, Page 1991-2005, December 2022., 2022
Abstract Premise Numerous processes influence plant distributions and co‐occurrence patterns, including ecological sorting, limiting similarity, and stochastic effects. To discriminate among these processes and determine the spatial scales at which they operate, we investigated how functional traits and phylogenetic relatedness influence the ...

The complete mitochondrial genome of Mactra quadrangularis (Mactridae)

open access: yesMitochondrial DNA. Part B. Resources, 2021
The whole mitochondrial genome sequence of Mactra quadrangularis (Reeve, 1854) was determined. It had a total length of 16,848 bp and it contained 12 protein coding genes, 2 ribosome RNA genes, and 22 transfer RNA genes. The base composition was 25.75% A,

Genome-scale phylogenetic analysis finds extensive gene transfer among Fungi [PDF]

open access: yes, 2015
Although the role of lateral gene transfer is well recognized in the evolution of bacteria, it is generally assumed that it has had less influence among eukaryotes.

The relationship between chlorophyllous spores and mycorrhizal associations in ferns: evidence from an evolutionary approach

open access: yesAmerican Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022
Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.

Genome Mining Enabled by Biosynthetic Characterization Uncovers a Class of Benzoxazolinate‐Containing Natural Products in Diverse Bacteria

open access: yesAngewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
Benzoxazolinate is a rare bis‐heterocyclic moiety that interacts with proteins and DNA. It was found that a putative acyl AMP‐ligase mediates the last cyclization step to afford benzoxazolinate. The enzyme was then used as a probe for genome mining, which led to the discovery of a new class of benzoxazolinate‐containing compounds in diverse bacteria ...

The complete mitochondrial genome of Batocera rubus Linnaeus, 1785 (Coleoptera: Cerambycidae)

open access: yesMitochondrial DNA. Part B. Resources, 2023
Batocera rubus severely impacts on the health of banyan trees. In this study, the whole mitochondrial genome for B. rubus was found to be 16,158 bp with a GC content of 23.9%, including 39.1% A, 37.0% T, 14.8% C, and 9.1% G.
