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.

Exchange of Protein Molecules Through Connections Between Higher Plant Plastids

, 1997
Individual plastids of vascular plants have generally been considered to be discrete autonomous entities that do not directly communicate with each other.

A mid‐Cretaceous monocot flower from the Dakota Sandstone of Kansas and its potential implications for the fossil record of palms

American Journal of Botany, EarlyView.
Abstract Premise Although the megafossil flora of the upper Albian–lower Cenomanian Dakota Formation in Kansas is well known for angiosperms, monocots have not been reported previously. Methods A mesofossil flower was discovered by X‐ray analysis of a specimen collected more than a century ago from the Dakota Sandstone of central Kansas.

Plastid translocon recycling in dinoflagellates demonstrates the portability of complex plastids between hosts. [PDF]

The plastids of photosynthetic organisms on land are predominantly "primary plastids," derived from an ancient endosymbiosis of a cyanobacterium.

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.

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

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.

Regulation of Expression and Evolution of Genes in Plastids of Rhodophytic Branch

Life, 2016
A novel algorithm and original software were used to cluster all proteins encoded in plastids of 72 species of the rhodophytic branch. The results are publicly available at http://lab6.iitp.ru/ppc/redline72/ in a database that allows fast identification ...

Antimicrobial Peptides and Peptidomimetics in Foods – A Synthetic Foray

ChemFoodChem, EarlyView.
This Review discusses AMPs in foods and their syntheses. It espouses facile methods to make them accessible and suggests their utility in the mitigation and eradication of the burgeoning maladies of antimicrobial and multidrug resistance (AMR and MDR).

Phylogenomic Insights into the Origin of Primary Plastids

, 2021
The origin of plastids was a major evolutionary event that paved the way for an astonishing diversification of photosynthetic eukaryotes. Plastids originated by endosymbiosis between a heterotrophic eukaryotic host and cyanobacteria, presumably in a ...
