How To Use cytokinin In A Sentence
- Researchers demonstrated they could make such blobs of tissue grow into either roots or shoots depending on the ratio of two critical plant hormones, auxins and cytokinins.

- Photosynthate supply and phytohormones, particularly cytokinins, interact with nitrogen supply through signal transduction pathways to control the expression of photosynthesis genes and development and senescence of leaves.
- In the xylem, following the application of nitrate, both the exudation rate and the concentration of the cytokinins increased, with ZR being the dominant species in the sap.
- This line appeared to be suitable to study in more detail the local consequences of enhanced cytokinin production in axillary meristems.
- Additional evidence that supports the of microbial derived growth regulators hypothesis is provided by recent reports that demonstrated the synthesis of cytokinins by facultative and obligate methylobacteria strains.
- Almost all leaves were vitrified and the total number of leaves on the longest shoot was also reduced compared with the plants growing on the other three cytokinin media.
- Zeatin is a natural cytokinin that induces morphogenesis. The Scientist
- For example, the cytokinins were discovered through work on tobacco pith tissue culture.
- Many insects synthesize plant cytokinins, which they administer to cause plants to form structures that protect the insect or its offspring.
