Genes that encode the biosynthetic enzymes for either the plant or bacterial pathway of either auxins or cytokinins were still unknown (Morris, 1986, 1995).
Similarly, the production of the plant growth regulators like auxins, particularly indole-3-acetic acid (IAA) and indole-3-pyruvic acid [22], zeatin, zeatin riboside and reacted cytokinins by Methylotrophs [21] has been reported as the factors that enhances plant growth of crops, the increase in the vegetative growth of the plant attributed to the increase in the yield of a crop.
The best regenerated shoots resulting from auxin, cytokinin treatment or combinations were then transferred to MS medium at full or half strength of mineral, with or without NAA, at 0.
Recent work in my lab has asked the question whether auxin plays a role in the expansion of leaves in the intact plant.

We knew how leaves sensed light and that auxins drove growth, but we didn't understand the pathway that connected these two fundamental systems," said Joanne Chory, professor and director of the Salk's Plant Biology Laboratory and a Howard Hughes Medical Institute investigator.
2,4-D is a synthetic auxin (plant hormone), and as such it is often used in laboratories for plant research and as a supplement in plant cell culture media such as MS medium (Dichlorophenoxyacetic acid, 2,4- (2,4-D): 1989.
Trial of auxins alone, and auxins with cytokinins combinations showed callus induction, among which 2,4-D (1.
2,4-D was found to be the best auxin for callus induction when compared to NAA.
The effect of auxins and cytokinins and their combinations on callus fresh and dry weight indicated that kin concentration outweighs the 2,4-D in the medium.
If either pruned or fed, the auxins (plant growth hormones that stimulate vegetative development) may override the chemical signals received by the shortening days and remain in growth late into the season.
