Floral dip transformación de la Arabidopsis thaliana Para el Examen de PTSO2:: β-glucuronidasa Reporter Expresión Génica

Overview

This article illustrates the floral-dip method of Agrobacterium tumefaciens-mediated transformation of Arabidopsis thaliana. By introducing a cell-cycle regulated promoter-reporter, pTSO2::β-glucuronidase (GUS), into Arabidopsis, it demonstrates how to detect GUS reporter expression in transgenic seedlings.
