Question

In which plants are natural cytokinin reported?​

Answer 1

Answer:

Cytokinins are present in all plant tissues. They are abundant in the root tip, the shoot apex and immature seeds. Their endogenous concentration is in the low nM range. Typically, several types of cytokinins and their modified forms are present in a given tissue.

Answer 2

Zeatin was the first natural cytokinin reported in plants.

• Cytokinins are plant-specific hormones that have an important role in the regulation of plants' cell cycle.

• It was first discovered by F.S Koog and C. Miller in the 1950s. These molecules promote cytokinesis which means cell division.

• The first-ever cytokinin discovered was adenine that was isolated from the DNA degradation product.

• The first natural cytokinin was discovered in the immature kernel called zeatin.
