Rethinking the evolution of eukaryotic metabolism: novel cellular partitioning of enzymes in stramenopiles links serine biosynthesis to glycolysis in mitochondria [PDF]

BMC Evolutionary Biology, 2017
Background An important feature of eukaryotic evolution is metabolic compartmentalization, in which certain pathways are restricted to the cytosol or specific organelles. Glycolysis in eukaryotes is described as a cytosolic process.

Identification and Evolution of Transcription Factors in Stramenopiles [PDF]

Nature Precedings, 2011
Background. Many transcriptional regulatory proteins have been identified and classified into several families on the basis of sequence similarity (Fukami, 2003), these families usually regulate important biological processes, such as ...

Single-cell genomics of multiple uncultured stramenopiles reveals underestimated functional diversity across oceans [PDF]

Nature Communications, 2018
The biology of many marine protists, such as stramenopiles, remains obscure. Here, the authors exploit single-cell genomics and metagenomics to analyze the genome content and apparent oceanic distribution of seven prevalent lineages of uncultured ...

Phylogenomic analyses of ochrophytes (stramenopiles) with an emphasis on neglected lineages

Molecular Phylogenetics and Evolution
Ochrophyta is a photosynthetic lineage that crowns the phylogenetic tree of stramenopiles, one of the major eukaryotic supergroups. Due to their ecological impact as a major primary producer, ochrophytes are relatively well-studied compared to the rest ...

A Multilocus Nanopore eDNA Workflow for Red Algal Diversity Assessment in an Algal Reef System. [PDF]

Ecol Evol
This study evaluates an Oxford Nanopore Technologies long‐read sequencing workflow using a multilocus eDNA approach to assess red algal (Rhodophyta) biodiversity in coastal waters. Results demonstrate that while a combination of rbcL, rpoC1, and psbA markers (but not COI‐5P) provides the most comprehensive taxonomic coverage, eDNA signals are heavily ...

Diatom communities in marine protected areas in the coral reefs in Lombok, Indonesia, using aqueous and sedimentary environmental DNA (eDNA) [PDF]

E3S Web of Conferences, 2023
Diatom has a specific response to particular ecological conditions. They live both planktonic and benthic, which is usually the diversity that has only been documented by microscopic.

Divergent functions of two clades of flavodoxin in diatoms mitigate oxidative stress and iron limitation

eLife, 2023
Phytoplankton rely on diverse mechanisms to adapt to the decreased iron bioavailability and oxidative stress-inducing conditions of today’s oxygenated oceans, including replacement of the iron-requiring ferredoxin electron shuttle protein with a less ...

Phospholipid signaling during stramenopile development [PDF]

Plant Signaling & Behavior, 2008
Development of sessile organisms requires adaptation to an ever-changing environment. In order to respond quickly to these challenges, complex signaling mechanisms have evolved to facilitate cellular modifications. The importance of phospholipid-based signaling pathways in plants, as well as animals, has recently been gaining attention.
