Plagiogravitropic growth in rooted stem cuttings of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) related to indole-3-acetic acid and cytokinins

Creator:

Chien, Ching-te

Abstract:

Endogenous concentrations of indole-3-acetic acid (IAA) and cytokinins were compared to the tendency for plagiogravitropjc growth in rooted stein cuttings of Douglas-fir. A chromatographic method was developed for the purification and quantitation of trace levels of IAA. Two elutions with reverse-phase high performance liquid chromatography (HPLC) using a fluorescence detector...

Functions and regulation of cytokinin glucosyltransferases

Creator:

Pineda Rodó, Albert

Abstract:

Cytokinins can be conjugated to N- and O-glucosides. While N-glucosylation generally leads to irretrievable loss of activity, O-glucosides are thought to play an important role in cytokinin storage and homeostasis since they can be hydrolyzed to the corresponding aglycones. The first zeatin O-glycosyltransferase genes isolated were ZOG1 and ZOX1 from...
