Plants respond to mild nitrogen deficiency by elongating their lateral roots. In this way, more nitrogen can be absorbed than before. Researchers have now discovered a hormonal regulatory module that ...

Morphological plasticity of root systems is critically important for plant survival because it allows plants to optimize their capacity to take up water and nutrients from the soil environment. Here ...

It is vital for plants to be able to adapt their root structure to changes in the soil. If there is a slight lack of nitrogen, many plants elongate their lateral roots. The hormone auxin plays an ...
