The buoyant density in CsCl of ribosomes from chloroplasts of the green alga Chlorella pyrenoidosa and two species of higher plants, Pisum sativum and Chenopodium album, has been studied. From the relative protein content it was calculated that 70S ribosomes from chloroplasts are much smaller than 80S cytoplasmic ribosomes (3.0-3.1 X 10(6) and 4.0 X 10(

Plastids and Carotenoid Accumulation.
Sub-cellular biochemistry, 2016Plastids are ubiquitously present in plants and are the organelles for carotenoid biosynthesis and storage. Based on their morphology and function, plastids are classified into various types, i.e. proplastids, etioplasts, chloroplasts, amyloplasts, and chromoplasts. All plastids, except proplastids, can synthesize carotenoids.

Biochimica et Biophysica Acta (BBA) - General Subjects, 2010
It is now widely accepted that an endosymbiotic cyanobacterium evolved into the plastid of the primary photosynthetic eukaryotes: glaucocystophytes, red algae, and green plants. It has been thought that during the evolution of plants, the peptidoglycan wall (or murein) was lost from the endosymbiont immediately after the branching off of the ...

Plastid Transcriptomics: An Important Tool For Plastid Functional Genomics
Protein & Peptide Letters, 2021Plastids in higher plants carry out specialized roles such as photosynthesis, nitrogen assimilation, biosynthesis of amino acids, fatty acids, isoprenoids, and various metabolites. Plastids arise from undifferentiated precursors known as proplastids, which are found in the root and shoot meristems. They are highly dynamic as they change their number,

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.

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 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.
