Endodermal cell-cell contact is required for the spatial control of Casparian band development in Arabidopsis thaliana.
BACKGROUND AND AIMS: Apoplasmic barriers in plants fulfil important roles such as the control of apoplasmic movement of substances and the protection against invasion of pathogens. The aim of this study was to describe the development of apoplasmic barriers (Casparian bands and suberin lamellae) in endodermal cells of Arabidopsis thaliana primary root and during lateral root initiation. METHODS: Modifications of the endodermal cell walls in roots of wild-type Landsberg erecta (Ler) and mutan...Expand abstract
