(ˈplæstəʊm)
Also plastom.
[a. G. plastom (O. Renner 1929, in Handb. d. Vererbungswissenschaft IIa. 32), f. plastid plastid n. 2, after genom genome.]
The sum-total of the genetic factors or information in the plastids of a cell.
| 1954 P. Michaelis in Adv. Genetics VI. 290, I propose..with Renner (1929) to include all extranuclear hereditary elements of the cell in the term plasmon, and to subdivide this into (1) the cytoplasmon, that is, the elements of the cytoplasm, and (2) the plastom, that is, the hereditary elements of the plastids, etc. 1965 Wettstein & Eriksson in S. J. Geerts Genetics Today xvi. 594 In higher plants two non-chromosomal genetic systems controlling chloroplast structure and function—the plastome and the plasmone—have long ago been recognized from the different modes of inheritance of certain chloroplast defects. 1967 Kirk & Tilney-Bassett Plastids ix. 277 There are as many as five genetically different plastoms within the subgenus Euoenothera. 1976 [see plasmon 2]. |
