Embryo rescue in plants -- a review
TL;DR: Embryo rescue holds great promise not only for effecting wide crosses, but also for obtaining plants from inherently weak embryos, obtaining haploid plants as well as for shortening the breeding cycle.

Auxin and gibberellin-like substances in coconut milk and malt extract
L. Dix,J. Van Staden +1 more
TL;DR: The results obtained correlate well with the responses reported by researchers using coconut milk and malt extract as additives to basal nutrient media in tissue culture experiments.

TL;DR: A major cytokinin found in coconut milk was isolted by using the tobacco callus growth-promoting assay as a guide during purification and found to be G3A2-ZR, which is one order of magnitude more potent than 1,3-diphenylurea and one order less potent than zeatin riboside.

Isolation of cytokinins from tRNA.
TL;DR: The method appears to be quantitative and resolves individual cytokinins such as the ribosides 6-(3-methyl-2-butenylamino)-9-β d -ribofuranosylpurine (2iPA) and 6-methylthio-9- β- d - ribofuranusylpurines (ms2 iPA).

TL;DR: The distribution of six cytokinins between aqueous buffers and several organic solvents was assessed and partition coefficients calculated and purified by solvent partition methods are discussed.

Evidence for the Presence of Cytokinins in Malt and Yeast Extracts
TL;DR: Partition chromatography on Sephadex LH-20 revealed the presence of an extremely active unidentified substance in both malt extract and coconut milk, but this compound is not diphenylurea as discussed by the authors.

Support of cellulose digestion by clostridium thermocellum in a kinetin-supplemented basal medium.
TL;DR: The results of this study show that intoxication due to endotoxin rapidly leads to alteration of liver NPSH levels, and this response is quite similar to that seen after tourniquet trauma and scalding in which marked differences are detectable within 4 hr of treatment.
