TLDR
Cytokinin-like substances were produced in higher amounts by soil isolates than by those isolated from the rhizosphere and mycorrhizosphere, and it is suggested that zeatin andZeatin riboside are likely to be among the cytokinin -like substances detected.Abstract:
Cytokinin-like substances were produced in higher amounts by soil isolates than by those isolated from the rhizosphere and mycorrhizosphere. However more bacterial strains isolated from the rhizosphere and mycorrhizosphere were capable of synthesizing cytokinin-like compounds. A distinct effect of pH on the production of these substances was found. It is suggested that zeatin and zeatin riboside are likely to be among the cytokinin-like substances detected.read more

Effect of the culture filtrates of Streptomyces on growth and productivity of wheat plants
TL;DR: Streptomyces olivaceoviridis, S. rimosus and S. rochei proved to possess a high capacity for the production of auxins, gibberellins and cytokinin-like substances, together with substantial levels of α-amylase and proteinase, and their effects on growth and yield of wheat.

Diazotrophic bacteria in root-free soil and in the root zone of pine (Pinus sylvestris L.) and oak (Quercus robur L.)
TL;DR: Biotin, p-aminobenzoic acid and yeast extract, applied both separately and in combination, significantly stimulated the activity of N2 fixation in three selected (nitrogenase highly active) bacterial strains, as compared to a control without growth factors.
