A gene that regulates the development of roots in vascular plants is also involved in the organ development of liverworts—land plants so old they don't even have proper roots. The Kobe University ...
Root hairs are tubular outgrowths of specialised epidermal cells that dramatically increase the absorptive surface area of plant roots. Development begins with positional specification within the root ...
The interaction between Hertwig's epithelial root sheath (HERS) and surrounding mesenchymal cells is crucial for root dentin formation. HERS influences tooth root development and odontoblast ...
