An evolutionary perspective on the kinome of malaria parasites [PDF]

open access: yes, 2012
Malaria parasites belong to an ancient lineage that diverged very early from the main branch of eukaryotes. The approximately 90-member plasmodial kinome includes a majority of eukaryotic protein kinases that clearly cluster within the AGC, CMGC, TKL ...

Detecting the Diversity of Mycoplasma and Ureaplasma Endosymbionts Hosted by Trichomonas vaginalis Isolates

open access: yesFrontiers in Microbiology, 2017
Objectives: The symbiosis of Trichomonas vaginalis and Mycoplasma hominis is the first described association between two obligate human parasites. Trichomonas is the niche and the vector for the transmission of M. hominis infection.

Mitochondria‐Targeting Abasic Site‐Reactive Probe (mTAP) Enables the Manipulation of Mitochondrial DNA Levels

open access: yesAngewandte Chemie, Volume 137, Issue 36, September 1, 2025.
Mitochondria‐targeting water‐soluble probe mTAP exclusively reacts with mitochondrial abasic sites, enabling the manipulation of mitochondrial DNA levels under genotoxic stress. Abstract Mitochondrial DNA (mtDNA) encodes essential genes for mitochondrial and cellular functions and acts as a cell signaling molecule in innate immune and inflammatory ...

Plastid origin: who, when and why?

open access: yesActa Societatis Botanicorum Poloniae, 2014
The origin of plastids is best explained by endosymbiotic theory, which dates back to the early 1900s. Three lines of evidence based on protein import machineries and molecular phylogenies of eukaryote (host) and cyanobacterial (endosymbiont) genes point

Segregation of a microsporidian parasite during host cell mitosis [PDF]

open access: yes, 1999
We investigated the segregation of an intracellular microsporidian parasite during host cell division. A time-course experiment was carried out to examine the distribution of parasites relative to host chromosomal DNA via light and electron microscopy.

Diversity in biosynthetic pathways of galactolipids in the light of endosymbiotic origin of chloroplasts

open access: yesFrontiers in Plant Science, 2016
Cyanobacteria and chloroplasts perform oxygenic photosynthesis, and share a common origin. Galactolipids are present in the photosynthetic membranes of both cyanobacteria and chloroplasts, but the biosynthetic pathways of the galactolipids are ...

Understanding the Wolbachia-mediated inhibition of arboviruses in mosquitoes: progress and challenges [PDF]

open access: yes, 2014
Arthropod-borne viruses (arboviruses) pose a considerable threat to human and animal health, yet effective control measures have proven difficult to implement, and novel means of controlling their replication in arthropod vectors, such as mosquitoes, are

Nuclear protein phosphatases with Kelch-repeat domains modulate the response to brassinosteroids in Arabidopsis [PDF]

open access: yes, 2004
Perception of the plant steroid hormone brassinolide (BL) by the membrane-associated receptor kinase BRI1 triggers the dephosphorylation and accumulation in the nucleus of the transcriptional modulators BES1 and BZR1.

Metabolic pathway redundancy within the apicomplexan-dinoflagellate radiation argues against an ancient chromalveolate plastid

open access: yesCommunicative & Integrative Biology, 2016
The chromalveolate hypothesis presents an attractively simple explanation for the presence of red algal-derived secondary plastids in 5 major eukaryotic lineages: “chromista” phyla, cryptophytes, haptophytes and ochrophytes; and alveolate phyla ...

Molecular evidence for ongoing complementarity and horizontal gene transfer in endosymbiotic systems of mealybugs

open access: yesFrontiers in Microbiology, 2014
Intracellular bacterial supply of essential amino acids is common among sap-feeding insects, thus complementing the scarcity of nitrogenous compounds in plant phloem. This is also the role of the two mealybug endosymbiotic systems whose genomes have been
