摘要: There is good evidence that bacteria and fungi produce cytokinins. A number of microorganisms excrete cytokinin-active nucleosides free bases into culture media. Cytokinin-active have also been found in the tRNA all examined so far. The production zeatin its derivatives by seems to be limited those which cause diseases higher plants or enter symbioses. symptoms plant-microbe interactions often resemble effects exogenously applied cytokinins, leading speculation microbes cytokinins host tissue. Some associations involving obligate parasites exhibit such symptoms, providing circumstantial these organisms
