How certain hormones control aspects of root branching in plants

Scientists describe that the plant hormone auxin together with an increased cell cycle activity leads to a boost in root branching in the common thale cress Arabidopsis thaliana. In addition, they showed that two proteins that are crucial for embryo development also play a critical role in root branching. These results could be used to raise plants that are fast-growing even in dry and nutrient-poor soils.
