TOPIC:BASICS OF INDUCTION AND COMPETENCE |CSIR NET |DEVELOPMENTAL BIOLOGY

INDUCTION-Signal induction refers to cascades of signaling events, during which a cell or tissue signals to another cell or tissue to influence its developmental fate. Signal that generate is called –inductive signal. The inductive signal can be growth and differentiation factors. There are 2 component to every inductive interaction-one is Inducer-tissue/cell that produce signal and second is Responder.

COMPETENCE-The ability to respond to a specific inductive signal is called competence. Competence can occur through expression of appropriate receptor or component of signaling pathway .The best  example of competence and induction is the process of eye lens development.
Instructive interaction-In instructive interaction, a signal from the inducing cell is necessary for initiating new gene expression in the responding cell.
Permissive interaction-The responding tissue contains all the potentials that are to be expressed, and needs only an environment that allows the expression of these traits.
