Trends in Ecology & Evolution, 1992
There has long been controversy over whether the plastids of green plants and algae, rhodophytes and chromophytes arose from a single primary endosymbiotic event or independently from several. DNA sequences from plastid genes are rapidly becoming available, but limitations of current phylogenetic inference techniques make it difficult to draw firm ...

Annual Review of Plant Biology, 2008
The ancestors of modern cyanobacteria invented O2-generating photosynthesis some 3.6 billion years ago. The conversion of water and CO2 into energy-rich sugars and O2 slowly transformed the planet, eventually creating the biosphere as we know it today.

Plant Physiology and Biochemistry, 2004
Plastids are essential organelles present in virtually all cells in plants and in green algae. The proteomes of plastids, and in particular of chloroplasts, have received significant amounts of attention in recent years. Various fractionation and mass spectrometry (MS) techniques have been applied to catalogue the chloroplast proteome and its membrane ...

Nature, 1948
IN a previous paper1, a method has been described for the detection of the enzyme phosphorylase in plant tissues. Briefly, it consists of incubating freehand sections of the tissue, previously freed of starch by starvation, in a buffered solution of glucose-1-phosphate, and subsequent staining in iodine–potassium iodide for the resultant starch.

Plastid Transformation in Tomato
2014Tomato (Solanum lycopersicum) is one of the most important vegetable crops and has long been an important model species in plant biology. Plastid biology in tomato is especially interesting due to the chloroplast-to-chromoplast conversion occurring during fruit ripening.

The Continuity of Plastids and the Differentiation of Plastid Populations
1980The 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, 2015Plant 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.

Plastids with or without galactoglycerolipids
Trends in Plant Science, 2014In structural, functional, and evolutionary terms, galactoglycerolipids are signature lipids of chloroplasts. Their presence in nongreen plastids has been demonstrated in angiosperms and diatoms. Thus, galactoglycerolipids are considered as a landmark of green and nongreen plastids, deriving from either a primary or secondary endosymbiosis.

Plastid Transformation in Eggplant
2014Eggplant (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 ...

Plastids in parasites of humans
BioEssays, 1997AbstractIt 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.
