(15) Pulse-labeling assays revealed a population of short-lived proteins in plastids of dark-grown plants.
(16) The difference in rates of amino acid incorporation between etioplasts and chloroplasts is correlated with the state of development of the plastids.
(17) Distinctive features include a complex cytoskeleton which defines the cell organization and interconnects cell components; trichocysts which resemble those in other cryptoprotists; and two non-photosynthetic plastids.
(18) Somatic hybridization of plants by fusions of protoplasts or by uptake of nuclei and other organelles (plastids, mitochondria) or pure nucleic acids is another useful method.

(20) This clearly indicated a close phylogenetic relationship between the plastids of Rhodophyta and Chromophyta which seem to have evolved independently from the chloroplasts (polyphyletic origin).
Plastin
Definition:
(n.) A substance associated with nuclein in cell nuclei, and by some considered as the fundamental substance of the nucleus.
Example Sentences:
(1) Two methods to preserve gastrointestinal tract (GIT) organs and tissues, plastic coating (PC) and plastination (PN), were investigated and compared.
(2) Twelve cadaver achilles tendons were investigated by means of the plastination method.
(3) These candidate genes can be divided into 5 groups: signal transduction proteins (RB1, inhibin alpha, FLT1, and HOX4B), muscle-specific products [myosin light chain, desmin, and nicotinic cholinergic receptor subunits gamma and delta (CHRNG and CHRND)], extracellular matrix proteins (collagen type VI alpha 3 chain, elastin, and fibronectin), transformation-associated products (intestinal alkaline phosphatase and L-plastin), and other genes (esterase D).
(4) Both schedules used plasma activated partial thrombo-plastin time (P-APTT) for adjustment of heparin infusion and aimed at the same therapeutic interval for P-APTT (1.5-2 times the value in normal pooled plasma).
(5) With the present trend in decreased requests for autopsies to be performed, the method of plastination and videotaping coupled with more traditional teaching methods provides a way to expand the information and knowledge that may be obtained from each autopsy in an academic medical center.
(6) In this model natural recombinant hirudins, rHV2 and rHV2-Lys47 injected 5 min before thrombo-plastin totally inhibited thrombosis in the same micrograms range as heparin or natural hirudin extracted from leeches.
(7) Fimbrin is also homologous in sequence with human L-plastin and T-plastin.
(8) A technique of plastination and its application to the preservation of oral pathology teaching specimens is presented.
(9) A microangiography of all femora occurred and after plastination transparent slices were produced.
(10) By means of macroscopic preparations and plastinated crossections of human bodies in the regions of the mons pubis a flat flat-pad (corpus adiposum), covered by connective tissue, was found, which can be demarcated from the subcutaneous adipose tissue.
(11) The finished plastinated specimen is dry to the touch, odorless, and nontoxic, yet it maintains its original shape and, in many cases, is reasonably close in color and consistency.
(12) Fibroblasts transformed in vitro by chemical carcinogens or SV40 virus and tumor-derived cancer cells of fibroblastoid or epithelioid origin usually express plastin and p220, a minor phosphorylated form of plastin.
