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 ...

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.

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 ...

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.

The possession of at least one form of plastid within its cytoplasm has been suggested as the feature which most clearly distinguishes a eukaryotic plant cell from an animal cell. Certainly no living cell of a higher plant has so far been described which completely lacks plastids.

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.

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
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 ...

Plastid Transformation in Soybean
2014The 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.
