Non-Skeletal Biomineralization by Eukaryotes: Matters of Moment and Gravity [PDF]

open access: yes, 2010
Skeletal biomineralisation by microbial eukaryotes significantly affects the global biogeochemical cycles of carbon, silicon and calcium. Non-skeletal biomineralisation by eukaryotic cells, with precipitates retained within the cell interior, can ...

A single-cell genomics pipeline for environmental microbial eukaryotes

open access: yesiScience, 2021
Summary: Single-cell sequencing of environmental microorganisms is an essential component of the microbial ecology toolkit. However, large-scale targeted single-cell sequencing for the whole-genome recovery of uncultivated eukaryotes is lagging.

The evolutionary history of histone H3 suggests a deep eukaryotic root of chromatin modifying mechanisms [PDF]

open access: yes, 2010
Background The phenotype of an organism is an outcome of both its genotype, encoding the primary sequence of proteins, and the developmental orchestration of gene expression.

Chromista

open access: yes, 2022
Gomphonema firmum Skvortzow 1937, Philippine J. Sci. 62: 353, fig. 10: 12. LM (Figs. 1–13). The valves are heteropolar, clavate-lanceolate with broadly rounded poles almost equal in width; the broadest portion of the valve is near the central area, length 54–125 µm, width 16.5–21 µm.

Are genetic databases sufficiently populated to detect non-indigenous species? [PDF]

open access: yes, 2016
Correct species identifications are of tremendous importance for invasion ecology, as mistakes could lead to misdirecting limited resources against harmless species or inaction against problematic ones.

The Type III Secretion System of Biocontrol Pseudomonas fluorescens KD Targets the Phytopathogenic Chromista Pythium ultimum and Promotes Cucumber Protection

open access: yesMolecular Plant-Microbe Interactions, 2005
The type III secretion system (TTSS) is used by Proteobacteria for pathogenic or symbiotic interaction with plant and animal hosts. Recently, TTSSgenes thought to originate from the phytopathogen Pseudomonas syringae were evidenced in Pseudomonas ...

Kingdoms Protozoa and Chromista and the eozoan root of the eukaryotic tree [PDF]

open access: yesBiology Letters, 2009
I discuss eukaryotic deep phylogeny and reclassify the basal eukaryotic kingdom Protozoa and derived kingdom Chromista in the light of multigene trees. I transfer the formerly protozoan Heliozoa and infrakingdoms Alveolata and Rhizaria into Chromista, which is sister to kingdom Plantae and arguably originated by synergistic double internal
