The Continuity of Plastids and the Differentiation of Plastid Populations

1980
The development of a proplastid into a chloroplast is only one aspect of the development of the photosynthetic system. We have to ask further questions about (1) the continuity of plastids from cell to cell, and (2) how the number of plastids in a cell is regulated.

Crystalloids in apparent autophagic plastids: Remnants of plastids or peroxisomes?

Journal of Plant Physiology, 2015
Plant macroautophagy is carried out by autophagosome-type organelles. Recent evidence suggests that plastids also can carry out macroautophagy. The double membrane at the surface of plastids apparently invaginates, forming an intraplastidial space. This space contains a portion of cytoplasm that apparently becomes degraded.

Bilateral Communication between Plastid and the Nucleus: Plastid Protein Import and Plastid-to-Nucleus Retrograde Signaling

Bioscience, Biotechnology and Biochemistry, 2010
Plastids are a diverse group of organelles found in plants and some parasites. Chloroplasts are the archetypical plastids and are present in photosynthetic plant cells. Because most plastid proteins are encoded by the nuclear genome, plastid biogenesis relies on importing these proteins into the plastid.

Plastids in parasites of humans

BioEssays, 1997
AbstractIt has recently emerged that malarial, toxoplasmodial and related parasites contain a vestigial plastid (the organelle in which photosynthesis occurs in plants and algae). The function of the plastid in these obligate intracellular parasites has not been established.

Synthetic biology in plastids

The Plant Journal, 2013
SummaryPlastids (chloroplasts) harbor a small gene‐dense genome that is amenable to genetic manipulation by transformation. During 1 billion years of evolution from the cyanobacterial endosymbiont to present‐day chloroplasts, the plastid genome has undergone a dramatic size reduction, mainly as a result of gene losses and the large‐scale transfer of ...

Plastid Transformation in Eggplant

2014
Eggplant (Solanum melongena L.) is an important vegetable crop of tropical and temperate regions of the world. Here we describe a procedure for eggplant plastid transformation, which involves preparation of explants, biolistic delivery of plastid transformation vector into green stem segments, selection procedure, and identification of the ...

Protein expression in plastids

Current Opinion in Plant Biology, 2001
The genome of the plastid has generated much interest as a target for plant transformation. The characteristics of plastid transgenes both reflect the prokaryotic origin of plastid organelles and provide a unique set of features that are currently lacking in genes introduced into the plant nucleus. Recent progress has been made in understanding plastid

Plastid Transformation in Soybean

2014
The biotechnological potential of plastid genetic engineering has been illustrated in a limited number of higher plant species. We have developed a reproducible method to generate plastid transformants in soybean (Glycine max), a crop of major agronomic importance.

Evolutionary History of Plastids

The Biological Bulletin, 1999
A major biological event contributing to the biodiversity of present-day organisms was the enslavement of a photosynthetic eubacterium by a primitive eukaryote and its entrapment as an integral part of the cell: the plastid. Since the first acquisition by eukaryotes of photosynthetic capability by primary endosymbiosis, two major lineages (red and ...
