Mitochondrial mRNA oligocitydylation occurs in Chlorophyceae and Ulvales but not Bryopsidales or Trebouxiophyceae [PDF]

Journal of Phycology, Volume 61, Issue 5, Page 1195-1205, October 2025.
Abstract Mitochondrial mRNAs in the green algal class Chlorophyceae have non‐template 3' oligo‐cytosine‐rich additions, also known as oligo(C), polycitydylation, or poly(C) “tails.” These oligonucleotide additions are believed to be unique to green algal mitochondria, as none have been observed in any other organism.

Mass development of a filamentous and likely nitrophilous aerophytic green alga on tree bark: Apatococcus ammoniophilus sp. nov. (Chlorophyta, Trebouxiophyceae) [PDF]

Frontiers in Microbiology
IntroductionA filamentous green alga forming significant biomass on twigs and needles was observed to have increased invasively in Denmark in recent decades.

Complete mitochondrial genome of Micractinium pusillum CCAP 231/1 (Chlorellaceae, Trebouxiophyceae) [PDF]

Mitochondrial DNA. Part B. Resources, 2020
The mitochondrial genome of Micractinium pusillum CCAP 231/1 was completely sequenced. This mitogenome has 70,061 bp in length and consists of 62 genes including 32 protein-coding, 3 rRNA, and 27 tRNA genes. The overall GC content of the genome is 31.3%.

Micractinium tetrahymenae (Trebouxiophyceae, Chlorophyta), a New Endosymbiont Isolated from Ciliates [PDF]

Diversity, 2020
Endosymbiosis between coccoid green algae and ciliates are widely distributed and occur in various phylogenetic lineages among the Ciliophora. Most mixotrophic ciliates live in symbiosis with different species and genera of the so-called Chlorella clade (

Molecular phylogeny and comparative chloroplast genome analysis of the type species Crucigenia quadrata [PDF]

BMC Plant Biology
Background The confused taxonomic classification of Crucigenia is mainly inferred through morphological evidence and few nuclear genes and chloroplast genomic fragments. The phylogenetic status of C.

Zoospore diversity and sexual reproduction in the lichen‐forming genus Trebouxia: From neglected evidence to new facts [PDF]

Plant Biology, Volume 27, Issue 6, Page 1137-1149, October 2025.
This study clarifies the role of flagellate cells in four Trebouxia species. Using innovative techniques, we could distinguish between zoospores and gametes, providing the first detailed evidence of sex. Abstract Trebouxia is one of the most frequent genera of green microalgae that occur as photobionts in lichens.

Phylogenomics reveals the evolutionary origins of lichenization in chlorophyte algae [PDF]

Nature Communications
Mutualistic symbioses have contributed to major transitions in the evolution of life. Here, we investigate the evolutionary history and the molecular innovations at the origin of lichens, which are a symbiosis established between fungi and green algae or

A Minority of Desert Cyanobacteria and Algae Is Responsible for the Bulk of CO2 Fixation [PDF]

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Cyanobacteria and algae are the major photosynthetic organisms in deserts because they survive desiccation, high solar radiation and extreme temperature fluctuations better than other plants. Under favourable conditions, desert cyanobacteria and algae evidently photosynthesise.

Chromosome‐level genome assembly of the photobiont microalga Trebouxia sp. ‘A48’ from the lichen Xanthoria parietina [PDF]

New Phytologist, Volume 249, Issue 2, Page 1036-1052, January 2026.
Summary Lichens are symbiotic assemblies consisting of multiple organisms, chiefly a fungus and a photosynthetic microorganism, or photobiont. Among diverse photobionts, the most prevalent is the chlorophyte alga Trebouxia. We produced a chromosome‐level assembly of Trebouxia sp. ‘A48’, a photobiont of Xanthoria parietina. The genome was assembled into
