6-(γ,γ-Dimethylallylamino)purine (2iP) is a bacteria-derived riboside cytokinin used to grow plant tissues such as tobacco and soybean callus. 2iP is a precursor of the cytokinin Zeatin. 2iP has been used in Schenk and Hildebrandt medium to support in vitro propagation of microshoot cultures from shoot tips of Genista plants.
The growth rates of tobacco callus tissues on media containing 10(-6) to 10 mum 6-(gamma,gamma-dimethylallylamino)purine (2iP) were measured. At concentrations of 10(-4) mum and above growth rates were exponential and dependent on cytokinin concentration. At 2iP concentrations of 10(-4) to
A 6-(gamma,gamma-dimethylallylamino) purine-like compound was found in the culture medium of Rhizopogon roseolus, which had been shown earlier to synthesize zeatin. The role of 6-(gamma,gamma-dimethylallylamino) purine as a precursor of zeatin was studied. Rhizopogon was furnished with 6-(gamma,gamma-dimethylallylamino) purine-8-(14)C. Cochromatography
Studies on the effect of post culture liquids of actinomycetes on cytokinin-like substances production by mycorrhizal fungi have revealed that actinomycete metabolites inhibited or stimulated the synthesis of these compounds. The results of chromatographic analyses suggest, that substances stimulating the
Haemoglobin genes have been found in a number of plant species, but the number of genes known has been too small to allow effective evolutionary inferences. We present nine new non-symbiotic haemoglobin sequences from a range of plants, including class

Cytokinins are important purine derivatives that act as redifferentiation-inducing hormones to control many processes in plants. Cytokinins such as isopentenyladenine (IPA) and kinetin are very effective at inducing the granulocytic differentiation of human myeloid leukemia HL-60 cells. We examined the
