Scientists have investigated how the thale cress, Arabidopsis thaliana, forms its first roots: the root founder cell in the tiny group of cells contained in the seed is activated by a combination of a plant hormone and a transcription factor. These insights could contribute to the breeding of plants with a particularly effective root system in the future.
