Concentration and Distribution of Nuclei and Plastids in Xylem Cells in Cunninghamia lanceolata and Aquilaria sinensis

BioResources, 2015
After programmed cell death (PCD), heartwood formation, storage, and processing, wood DNA degradation occurs to varying degrees. The concentration and distribution of nuclei and plastids in xylem cells of Cunninghamia lanceolata and Aquilaria sinensis ...

Searching for α−solenoid proteins involved in organellar gene expression

BMC Genomics
Background In photosynthetic eukaryotes of the green lineage, the expression of the chloroplast genome is mainly regulated post-transcriptionally, by RNA-binding proteins encoded in the nuclear genome termed organelle trans-acting factors.

Organization, function and substrates of the essential Clp protease system in plastids.

Biochimica et Biophysica Acta, 2015
Intra-plastid proteolysis is essential in plastid biogenesis, differentiation and plastid protein homeostasis (proteostasis). We provide a comprehensive review of the Clp protease system present in all plastid types and we draw lessons from structural ...

In Arabidopsis thaliana Substrate Recognition and Tissue- as Well as Plastid Type-Specific Expression Define the Roles of Distinct Small Subunits of Isopropylmalate Isomerase

Frontiers in Plant Science, 2020
In Arabidopsis thaliana, the heterodimeric isopropylmalate isomerase (IPMI) is composed of a single large (IPMI LSU1) and one of three different small subunits (IPMI SSU1 to 3). The function of IPMI is defined by the small subunits. IPMI SSU1 is required

Sucrose Metabolism in Plastids [PDF]

Plant Physiology, 2001
Abstract The question whether sucrose (Suc) is present inside plastids has been long debated. Low Suc levels were reported to be present inside isolated chloroplasts, but these were argued to be artifacts of the isolation procedures used.

Updating algal evolutionary relationships through plastid genome sequencing: did alveolate plastids emerge through endosymbiosis of an ochrophyte?

Scientific Reports, 2015
Algae with secondary plastids of a red algal origin, such as ochrophytes (photosynthetic stramenopiles), are diverse and ecologically important, yet their evolutionary history remains controversial.

Ultrastructural changes during megasporogenesis in Epipactis (Orchidaceae)

Acta Societatis Botanicorum Poloniae, 2014
Plastids were temporarily localized within the micropylar portion of the early first prophase Epipactis meiocyte. Some of these plastids were observed in close proximity to the nuclear envelope.

Complex Plastids and the Evolution of the Marine Phytoplankton

Journal of Marine Science and Engineering, 2023
Photosynthesis allows for the formation of biomass from inorganic carbon and therefore greatly enhances the amount of organic material on planet Earth.

Plastids and mitochondria comportment in dividing meiocytes of Psilotum nudum

Acta Societatis Botanicorum Poloniae, 2014
In prophase I meiocyte plastids and mitochondria were situated at random. By telophase I plastids and mitochondria were aggregated in an equatorial plane.

Isolation of Carrot Chromoplasts and Assessment of Their Carotenoid Content and Bioaccessibility

Molecules
The bioaccessibility (fraction of compounds released from the food matrix and available for absorption) and carotenoid content of carrot chromoplasts obtained through high-speed centrifugation using sucrose gradients were assessed.
