Analyse de végétaux de promoteur : Identification et caractérisation de racine Nodule promoteur spécifique chez le haricot commun

Overview

This article presents a protocol for identifying, isolating, and cloning plant promoters, specifically focusing on the characterization of a nodule-specific promoter in common bean hairy roots. The methodologies for hairy root induction and studying promoter expression patterns in transgenic hairy roots are demonstrated.
