Cytokinin dehydrogenase precursor
WebCytokinin dehydrogenase was confirmed to be present in the apoplast of cells. Co-staining of enzyme activity for laccase, an enzyme poised to function on the cell wall in the apoplast, in those tissues suggests a possible cooperation of the enzymes in cytokinin degradation. WebApr 13, 2024 · In vitro experiments to induce Rafflesia seed germination using various plant growth regulators such as gibberellins, ethylene, brassinolide, and cytokinin have also been unsuccessful (Molina et al., 2024). Even the synthetic strigol, GR24, known to stimulate seed germination in plant parasites of Orobanchaceae, did not induce germination.
