Gain and loss of elongation factor genes in green algae [PDF]

, 2009
BackgroundTwo key genes of the translational apparatus, elongation factor-1 alpha (EF-1a) and elongation factor-like (EFL) have an almost mutually exclusive distribution in eukaryotes.

The complete chloroplast DNA sequence of the green alga Oltmannsiellopsis viridis reveals a distinctive quadripartite architecture in the chloroplast genome of early diverging ulvophytes

BMC Biology, 2006
Background The phylum Chlorophyta contains the majority of the green algae and is divided into four classes. The basal position of the Prasinophyceae has been well documented, but the divergence order of the Ulvophyceae, Trebouxiophyceae and ...

Still uncharted waters: Are we truly advancing in molecular studies of green and brown macroalgae (Ulvophyceae and Phaeophyceae) in Brazil? [PDF]

Acta Botânica Brasílica
Despite the ecological importance of marine macroalgae, molecular studies on green and brown algae in Brazil remain limited in scope and continuity. This review presents a scientometric analysis of DNA sequences deposited in GenBank from 1998 to 2023 ...

Chloroplast DNA sequence of the green alga Oedogonium cardiacum (Chlorophyceae): Unique genome architecture, derived characters shared with the Chaetophorales and novel genes acquired through horizontal transfer [PDF]

, 2008
Background To gain insight into the branching order of the five main lineages currently recognized in the green algal class Chlorophyceae and to expand our understanding of chloroplast genome evolution, we have undertaken the sequencing of chloroplast ...

Organellar inheritance in the green lineage: insights from Ostreococcus tauri [PDF]

, 2013
Along the green lineage (Chlorophyta and Streptophyta), mitochondria and chloroplast are mainly uniparentally transmitted and their evolution is thus clonal. The mode of organellar inheritance in their ancestor is less certain.

Divergent copies of the large inverted repeat in the chloroplast genomes of ulvophycean green algae

Scientific Reports, 2017
The chloroplast genomes of many algae and almost all land plants carry two identical copies of a large inverted repeat (IR) sequence that can pair for flip-flop recombination and undergo expansion/contraction. Although the IR has been lost multiple times

Molecular characterization of eukaryotic algal communities in the tropical phyllosphere based on real-time sequencing of the 18S rDNA gene

BMC Plant Biology, 2018
Backgroud Foliicolous algae are a common occurrence in tropical forests. They are referable to a few simple morphotypes (unicellular, sarcinoid-like or filamentous), which makes their morphology of limited usefulness for taxonomic studies and species ...

Mitochondrial Molecular Adaptations and Life History Strategies Coevolve in Plants [PDF]

, 2008
Messenger RNA secondary structure prevents mutations at functionally important sites. Mutations at exposed sites would cause micro-adaptations, niche-specialization, and therefore, can be thought to promote K-strategists. Exposing, rather than protecting,

Complete chloroplast genome of an invasive marine macroalga Ulva californica (Ulvophyceae, Chlorophyta)

Mitochondrial DNA. Part B. Resources, 2022
Species belonging to Ulva (Ulvophyceae, Chlorophyta) are one of the major members of invasive seaweeds. Ulva californica Wille 1899 was originally believed to be native to the Pacific coast of North America, while in recent years it has been reported as ...
