| 21. | Cytokinins participate in local and long-distance signalling, with the same transport mechanism as purines and nucleosides.
|
| 22. | In botany, plant hormones cytokinins were first called kinins, but the name was changed to avoid confusion.
|
| 23. | Other players that have a conserved role in defining leaf primordia are the phytohormones auxin, gibberelin and cytokinin.
|
| 24. | For example, the ratio of auxin to cytokinin in certain plant tissues determines initiation of root versus shoot buds.
|
| 25. | When the shoot is cut off, the lateral bud begins to lengthen which is mediated by a release of cytokinin.
|
| 26. | They are converted to chloroplasts via the stimulation of chlorophyll synthesis by the plant hormone cytokinin soon after exposure to light.
|
| 27. | These exudates can include, but are not limited to, flavonoids, diterpenes, cytokinins, hormones and other nutrients.
|
| 28. | When sprayed on flowers, any of the plant hormones gibberellin, auxin and cytokinin could stimulate the development of parthenocarpic fruit.
|
| 29. | When auxin and cytokinin are applied to callus, rooting can be generated if the auxin concentration is higher than cytokinin concentration.
|
| 30. | When auxin and cytokinin are applied to callus, rooting can be generated if the auxin concentration is higher than cytokinin concentration.
