Pregunta:

How does it work? (SHR and SCR)

Autor: Alex Rapai



Respuesta:

The SHR mRNA is expressed in the vascular tissue. The SHR protein is expressed in the vascular tissue. It moves into the adjacent ground tissue where it becomes localised to the nucleus. The SHT protein can then activate SCR transcription in the ground tissue. In the ground tissue, the SHR protein functions as a transcription factor. It induces expression of SCR and other endodermis-specific genes. SCR is also required for periclinal cell divisions which lead to the generation of two layers of ground tissue.
