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.
-
Among the plant growth regulators dynamically intervening in this mechanism, indole acetic acid, abscisic acid and cytokinins are cited most often.
-
Herbivorous tephritid flies host an endosymbiotic bacterium until recently classified in the genus Erwinia, a galling plant pathogen capable of synthesizing auxins and cytokinins.

-
Cytokinins, gibberellins, and auxin have been applied to promote cell division during the early stages of fruit growth in many species.
