A contemplation on the secondary origin of green algal and plant plastids

Acta Societatis Botanicorum Poloniae, 2014
A single origin of plastids and the monophyly of three “primary” plastid-containing groups – the Chloroplastida (or Viridiplantae; green algae+land plants), Rhodophyta, and Glaucophyta – are widely accepted, mainstream hypotheses that form the basis for ...

Evidence for the Retention of Two Evolutionary Distinct Plastids in Dinoflagellates with Diatom Endosymbionts

Genome Biology and Evolution, 2014
Dinoflagellates harboring diatom endosymbionts (termed “dinotoms”) have undergone a process often referred to as “tertiary endosymbiosis”—the uptake of algae containing secondary plastids and integration of those plastids into the new host.

Plastid Envelope-Localized Proteins Exhibit a Stochastic Spatiotemporal Relationship to Stromules

Frontiers in Plant Science, 2018
Plastids in the viridiplantae sporadically form thin tubules called stromules that increase the interactive surface between the plastid and the surrounding cytoplasm.

A non-photosynthetic green alga illuminates the reductive evolution of plastid electron transport systems

BMC Biology, 2020
Background Plastid electron transport systems are essential not only for photosynthesis but also for dissipating excess reducing power and sinking excess electrons generated by various redox reactions.

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.

The Arabidopsis minE mutation causes new plastid and FtsZ1 localization phenotypes in the leaf epidermis

Frontiers in Plant Science, 2015
Plastids in the leaf epidermal cells of plants are regarded as immature chloroplasts that, like mesophyll chloroplasts, undergo binary fission. While mesophyll chloroplasts have generally been used to study plastid division, recent studies have suggested

Formation and excretion of autophagic plastids (plastolysomes) in Brassica napus embryogenic microspores

Frontiers in Plant Science, 2015
The change in developmental fate of microspores reprogrammed towards embryogenesis is a complex but fascinating experimental system where microspores undergo dramatic changes derived from the developmental switch.

The physical and functional borders of transit peptide-like sequences in secondary endosymbionts

BMC Plant Biology, 2010
Background Plastids rely on protein supply by their host cells. In plastids surrounded by two membranes (primary plastids) targeting of these proteins is facilitated by an N-terminal targeting signal, the transit peptide.

The induction of stromule formation by a plant DNA-virus in epidermal leaf tissues suggests a novel intra- and intercellular macromolecular trafficking route

Frontiers in Plant Science, 2012
Stromules are dynamic thin protrusions of membrane envelope from plant cell plastids. Despite considerable progress in understanding the importance of certain cytoskeleton elements and motor proteins for stromule maintenance, their function within the ...

Genetic and ultrastructural studies on an orange coloured chlorophyll mutant of winter rye (Secale cereale L.)

Acta Societatis Botanicorum Poloniae, 2014
The feature of the orange colour of young seedlings, which appeared in inbred generation S2 of a short straw form of winter rye cultivated in Jeleniec is described.
