Cytokinins from a variant strain of cultured soybean cells

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 ribonucle...

Description
Summary: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 ribonuclectide. 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.
