…To grow this callus continuously and successively, it is necessary to add nutrients, auxins, coconut milk, herring sperm, yeast hydrolysate, etc. to the medium. In 1955, Folke Skoog and his group in the United States purified a large amount of yeast DNA hydrolysate and isolated a substance that had the activity of promoting callus growth. They named it kinetin and proved that it was 6-furfurylaminopurine. After that, many researchers showed the existence of substances with kinetin-like activity in higher plants, and in 1964, DS Letham and CO Miller independently isolated a new kinetin-like substance, zeatin, from corn, and many kinetin-like substances were subsequently isolated from plants. … *Some of the terminology that mentions "kinetin" is listed below.

…このカルスを継続的かつ継代的に増殖させるためには,培地に栄養素,オーキシンのほかに,ココナッツミルク,ニシンの精子,酵母の加水分解物などを添加することが必要である。1955年アメリカのスクーグFolke Skoogらのグループは,大量の酵母DNA加水分解物を精製して,カルスの増殖を促進する活性を有する物質を単離し,これをカイネチンkinetinと命名,それが6‐フルフリルアミノプリンであることを証明した。その後,高等植物にもカイネチン様活性を有する物質の存在が多数の研究者によって示され,1964年にリーサムD.S.LethamとミラーC.O.Millerが独立に新しいカイネチン様物質ゼアチンzeatinをトウモロコシから単離し,その後も多数のカイネチン様物質が植物から単離された。… ※「kinetin」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
