Red to Green: A Lipid Biomarker Record of Tonian‐Ediacaran Algae in Siberia
Geobiology, Volume 24, Issue 5, September/October 2026.ABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...

The Manganese-stabilizing Protein Is Required for Photosystem II Assembly/Stability and Photoautotrophy in Higher Plants [PDF]
Journal of Biological Chemistry, 2005 Interfering RNA was used to suppress the expression of two genes that encode the manganese-stabilizing protein of photosystem II in Arabidopsis thaliana, MSP-1 (encoded by psbO-1, At5g66570), and MSP-2 (encoded by psbO-2, At3g50820). A phenotypic series of transgenic plants was recovered that expressed high, intermediate, and low amounts of these two ...

MicrobiologyOpen, Volume 15, Issue 4, August 2026.An integrated bioinformatic pipeline combining taxonomic, functional, and network analyses revealed host‐driven structuring of macroalgal microbiomes. Phaeophyceae hosted distinct epiphytic communities enriched in chemoheterotrophy and polysaccharide degradation, highlighting metabolic coupling, keystone taxa, and a standardized framework for ...

Photosynthetica, 2001 We studied the relationships between the degree of photoautotrophy, photosynthetic capacity, and extent of photoinhibition of Gardenia jasminoides Ellis plantlets in vitro. Two successive micropropagation stages (shoot multiplication and root induction), and three culture conditions [tube cap closure, photosynthetic photon flux density (PPFD), and ...

Acetate mutants and obligate photoautotrophy in Chlamydomonas eugametos
, 2023 Incorporation of C-14 labelled sodium acetate by three species of Chlamydomonas: C. eugametos, C. reinhardii and C. moewusii indicates that all three species assimilate and metabolize exogenous acetate. All three species have higher growth rate in the light with acetate than without. C. eugametos and C. moewusii, being obligate photoautotrophs, are not
