germ plasm
Wiktionary英語版での「Germplasm」の意味 |
germ plasm
別の表記
名詞
- (biology, dated or historical) The cytoplasm of germ cells.
- 1893, August Weismann, translated by W. Newton Parker and Harriet Rönnfeldt, The Germ-plasm: A Theory of Heredity, Charles Scribner's Sons, page 183:
- If heredity depends on the presence of a substance, the germ-plasm, which causes the production of the new individual by directing the process of division in ontogeny, in the course of which it becomes changed in a regular manner, the question arises as to how unaltered germ-plasm can nevertheless reappear in the germ-cells of the new individual.
- 1951, Bradley M. Patten, Early Embryology of the Chick, 4th edition, The Blakiston Company, page 10:
- The germ plasm is of paramount interest, not only to the biologist but to all thinking persons, because while the somatic cells cease to exist with the death of the individual whose body they constitute, the germ plasm may live on indefinitely in succeeding generations.
- 2014, Eva Jablonka, Marion J. Lamb, Evolution in Four Dimensions, The MIT Press (Bradford Books), page 19,
- Germplasm; seeds or tissues maintained for the purpose of animal or plant breeding, preservation or other research uses.
- 1976, Te-Tzu Chang, Manual on Genetic Conservation of Rice Germ Plasm for Evaluation and Utilization, International Rice Research Institute, page 56:
- Although the IRRI has taken on the global responsibility of conserving rice germ plasm, we find it necessary to enlist the collaboration of other international and national organizations in achieving the goals.
使用する際の注意点
- The biology term relates to the obsolete germ plasm theory (Keimplasmatheorie), described in 1892 by German biologist August Weismann. Through his theory he rejected Lamarckism and proposed what came to be called the Weismann barrier: the principle that germ cells can influence somatic cells, but not vice versa. Weismann's theory was made obsolete by genetics, but the idea that changes acquired during an organism's life cannot affect its offspring is still broadly accepted, albeit within a framework of epigenetic variable expression contrasting with mendelian heredity.

名詞

- Seeds or tissues maintained for the purpose of animal or plant breeding, preservation or other research uses.
- 1987, Aart van Schoonhove, Standard System for the Evaluation of Bean Germplasm, CIAT, page 5,
- Since the number of problems that affect the bean crop is large, researchers in national and international programs have formed a network on genetic improvement in which germplasm evaluation and research results are exchanged.
- 1989, Zhang Yihua, Dong Yushen, Development of Research on Crop Germplasm Resources in China, Lloyd Knutson, Allan K. Stoner (editors), Biotic Diversity and Germplasm Preservation, Global Imperatives, Kluwer Academic Publishers, Beltsville Symposia in Agricultural Research 13, page 125,
- 2000, R. K. Singh, et al., 9: Small and Medium Grained Aromatic Rices of India, R. K. Singh, U. S. Singh, G. S. Khush (editors), Aromatic Rices, Oxford & IBH Publishing Company, page 170,
