In Vitro Synthesis of Chlorophyll A in the Dark Triggers Accumulation of Chlorophyll A Apoproteins in Barley Etioplasts” [PDF]
, 1990 An in vitro translation system using lysed etioplasts was developed to test if the accumulation of plastid-encoded chlorophyll a apoproteins is dependent on the de novo synthesis of chlorophyll a.

Photoprotection and genetic autonomy of plastids in photosynthetic sea slugs [PDF]
, 2022 Certain sea slugs “steal” the photosynthetic cellular organelles, the plastids, from their prey algae and incorporate them, still functional, inside their own cells. These animals can then remain photosynthetic for months.

Integrative Zoology, EarlyView.The microbiome of polychaetes Syllis prolifera and Platynereis massiliensis complex changes in naturally acidified CO2 vents. A slight degree of acidification is associated with relevant changes in the microbial community, stressing the importance of investigations about the possible effects of ocean acidification on key biological and ecological ...

Frontiers in Plant Science, 2020 Organisms that have lost their photosynthetic capabilities are present in a variety of eukaryotic lineages, such as plants and disparate algal groups. Most of such non-photosynthetic eukaryotes still carry plastids, as these organelles retain essential ...

A potential cyanobacterial ancestor of Viridiplantae chloroplasts [PDF]
, 2011 The theory envisaging the origin of plastids from endosymbiotic cyanobacteria is well-established but it is difficult to explain the evolution (spread) of plastids in phylogenetically diverse plant groups.

Markov-modulated continuous-time Markov chains to identify site- and branch-specific evolutionary variation [PDF]
arXiv, 2019 Markov models of character substitution on phylogenies form the foundation of phylogenetic inference frameworks. Early models made the simplifying assumption that the substitution process is homogeneous over time and across sites in the molecular sequence alignment.

Diatom triacylglycerol metabolism: from carbon fixation to lipid droplet degradation
Biological Reviews, EarlyView.ABSTRACT Diatoms are a prominent microalgae family that has attracted interest for its production of molecules of biotechnological interest. Their fatty acid profile is rich in health‐beneficial omega‐3 eicosapentaenoic acid (EPA). Furthermore, under nutrient‐deprived conditions, many diatom species, notably Phaeodactylum tricornutum, Thalassiosira ...

Expression of the chloroplast genome: modern concepts and experimental approaches
Вавиловский журнал генетики и селекции, 2015 A unique feature of plants is the presence of two extranuclear genomes, chloroplasts and mitochondria. The chloroplast genome is relatively small, 100–120 genes, which encode less than 5 % of all proteins required for plastids to function.

Reconstruction of the 3D structure and developmental history of plant cells and tissues [PDF]
arXiv, 2012 Modern spatial microscopy has provided developmental biology with powerful research tools. However, the recent significant technological breakthroughs have inevitably led to technical "bottlenecks" for the application of the new procedures to other tasks. We have developed a protocol for the 3D reconstruction of plant organelles and tissues from stacks
