Several reports indicate that TDZ may act through modulation of the endogenous plant growth regulators, either directly or as a result of induced stress, and several possibilities include the modification in cell membranes, energy levels, nutrient uptake, or nutrient assimilation.
Thidiazuron induces shoot organogenesis at low concentrations and somatic embryogenesis at high concentrations on leaf and petiole explants of African violet (Saintpaulia ionantha Wendl.)

These findings provide the first report of simultaneous shoot organogenesis and somatic embryogenesis of African violet explants in response to TDZ.

The results suggest that scented geranium plants were able to overcome metal stress through maintaining an efficient photosystem II activity, which is required for plant metabolism and physiological functions, as well as to overcomeMetal ion mediated stress, and restricting damage to the photosynthetic apparatus (reaction centers) by metal ions.
Role of melatonin in alleviating cold stress in Arabidopsis thaliana
The up‐regulation of cold signaling genes by melatonin may stimulate the biosynthesis of cold‐protecting compounds and contribute to the increased growth of plants treated with exogenous melatonin under cold stress.
Regeneration in Phaseolus vulgaris L.: High-frequency induction of direct shoot formation in intact seedlings by N6-benzylaminopurine and thidiazuron
Induction of prolific shoot formation in Phaseolus vulgaris L. cv. Kinghorn Wax was achieved by germinating mature seeds and growing seedlings on a medium supplemented with 10 μM thidiazuron (TDZ), a…

Thidiazuron induces high-frequency shoot regeneration in intact seedlings of pea (Pisum sativum), chickpea (Cicer arietinum) and lentil (Lens culinaris)
Of various cytokinins or compounds with cytokinin-like activity tested for inducing shoot formation in pea seeds cultures,TDZ was found to be most effective and inductive capability of TDZ was then tested in several other genotypes of Pisum sativum and two other large-seeded grain legumes.
Morphoregulatory role of thidiazuron : substitution of auxin and cytokinin requirement for the induction of somatic embryogenesis in geranium hypocotyl cultures.

Somatic embryogenesis was induced in hypocotyl explants of geranium (Pelargonium x hortorum) cultured on media supplemented with various concentrations of N-phenyl-N'-1,2,3-thiadiazol-5-ylurea…
Tryptophan is a precursor for melatonin and serotonin biosynthesis in in vitro regenerated St. John's wort (Hypericum perforatum L. cv. Anthos) plants

Significantly more radiolabel was recovered in serotonin relative to melatonin under low light conditions with this ratio being reversed under increased lighting, indicating that the rate of flow through this biosynthetic pathway is regulated, at least in part, by light.
Thidiazuron‐induced somatic embryogenesis in intact seedlings of peanut (Arachis hypogaea): Endogenous growth regulator levels and significance of cotyledons
It appeared that TDZ induced somatic embryogenesis in peanut by influencing endogenous levels of both auxin and cytokinins, while TDZ itself was detected only in the cotyledons.
