Cytokinin activities of thiozeatin and related compounds in Phaseolus callus culture bioassays
TLDR
The higher activity of thiozeatin than zeatin in this system may reside in the resistance of thIOzeatin to enzymatic attack, as P. vulgaris tissues contain an enzyme system capable of cleaving off unsaturated side chains of cytokinins.Citations

TL;DR: In vivo redox biosensing resolves the spatiotemporal dynamics of compartmental responses to local ROS generation and provide a basis for understanding how compartment-specific redox dynamics may operate in retrograde signaling and stress 67 acclimation in plants.

TL;DR: An enzyme activity that catalyzes conversion of N6-(Δ2-isopentenyl)adenosine (i6Ado) to adenosine was detected in cultured tobacco tissue by Paces et al. (1971) and Purification and characteristics of this enzyme in corn kernels have been studied.

Conversion of N6-(Δ2-Isopentenyl)adenosine to Adenosine by Enzyme Activity in Tobacco Tissue
TL;DR: By using [8-(14)C]-N(6)-(Delta(2)-isopentenyl)adenosine as a substrate, the presence of enzyme activity in a crude extract of tobacco tissue that converts this cytokinin into adenosine is detected.

Differential Cytokinin Structure-Activity Relationships in Phaseolus
TL;DR: The results suggest the possibility of employing cytokinin structure-activity relationships in distinguishing genotypic differences in cytokinIn function and metabolism.
