Philosophical Transactions of the Royal Society B: Biological Sciences, 2008 It is generally accepted that plastids first arose by acquisition of photosynthetic prokaryotic endosymbionts by non-photosynthetic eukaryotic hosts. It is also accepted that photosynthetic eukaryotes were acquired on several occasions as endosymbionts by non-photosynthetic eukaryote hosts to form secondary plastids.

Frontiers in Plant Science, 2023 Abiotic stress has a significant impact on plant growth and development. It causes changes in the subcellular organelles, which, due to their stress sensitivity, can be affected.

Structural regulation and dynamic behaviour of organelles during plant meiosis
Frontiers in Cell and Developmental Biology, 2022 Eukaryotes use various mechanisms to maintain cell division stability during sporogenesis, and in particular during meiosis to achieve production of haploid spores.

“Omics” insights into plastid behavior toward improved carotenoid accumulation
Frontiers in Plant Science, 2022 Plastids are a group of diverse organelles with conserved carotenoids synthesizing and sequestering functions in plants. They optimize the carotenoid composition and content in response to developmental transitions and environmental stimuli.

AoB PLANTS, 2010 Plastids undergo a process of binary fission in order to replicate. Plastid replication is required at two distinct stages of plant growth: during cell division to ensure correct plastid segregation, and during cell expansion and development to generate large populations of functional plastids, as in leaf mesophyll cells.

Stromule formation is dependent upon plastid size, plastid differentiation status and the density of plastids within the cell [PDF]
, 2004 Stromules are motile extensions of the plastid envelope membrane, whose roles are not fully understood. They are present on all plastid types but are more common and extensive on non-green plastids that are sparsely distributed within the cell.

Metabolic and molecular events occurring during chromoplast biogenesis [PDF]
, 2011 Chromoplasts are nonphotosynthetic plastids that accumulate carotenoids. They derive from other plastid forms, mostly chloroplasts. The biochemical events responsible for the interconversion of one plastid form into another are poorly documented. However,

Organellar DNA Polymerases in Complex Plastid-Bearing Algae
Biomolecules, 2019 DNA replication in plastids and mitochondria is generally regulated by nucleus-encoded proteins. In plants and red algae, a nucleus-encoded enzyme called POP (plant and protist organellar DNA polymerase) is involved in DNA replication in both organelles ...
