BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Auxins promote root initiation. Auxin induces both growth of pre-existing roots and root branching (lateral root initiation), and also adventitious root formation. As more native auxin is transported down the stem to the roots, the overall development of the roots is stimulated.

Detailed explanation-2: -Auxins are a family of plant hormones. They are mostly made in the tips of the growing stems and roots, which are known as apical meristems, and can diffuse to other parts of the stems or roots. Auxins control the growth of plants by promoting cell division and causing elongation in plant cells (the cells get longer).

Detailed explanation-3: -Root-generated Auxin Contributes to Root Development.

Detailed explanation-4: -Shoot and root development are coordinated by hormones, such as auxin and cytokinins (CKs). Auxin is primarily synthesized in shoots and actively transported to roots where it promotes root development (for recent reviews, see Peret et al., 2009; Coudert et al., 2010).

Detailed explanation-5: -Auxins. Auxins are a family of hormones found in plants. Auxins are mostly made in the tips of the shoots and roots, and can diffuse to other parts of the shoots or roots. They change the rate of elongation in plant cells, controlling how long they become.
