Abstract

A strain of soybean cells capable of growing on a tissue culture medium lacking a cytokinin produced at least 3 compounds active in the soybean cytokinin assay. The characteristics of these compounds were consistent with their being zeatin in the free form, zeatin ribonucleoside and zeatin ribonucleotide. Although the conversion from a cytokinin dependent to independent condition in this strain parallels the change of normal cells to crown gall tumor state in terms of the capacity to synthesize cell division substances, the soybean factors are distinct from the nicotinamide derivatives reported for tumor cells of Vinca.

摘要

一株能够在缺乏细胞分裂素的组织培养基上生长的大豆细胞系至少产生了 3 种在大豆细胞分裂素测定中具有活性的化合物。这些化合物的特性与其为游离的玉米素、玉米素核苷和玉米素核苷酸一致。尽管该菌株从细胞分裂素依赖状态到独立状态的转变与正常细胞向冠瘿瘤状态的转变在合成细胞分裂物质的能力方面相似,但大豆因子与长春花肿瘤细胞中报道的烟酰胺衍生物不同。
