Salt stress is a worldwide problem for agriculture, because salinity of the soil decreases plant growth and crop yield. The root is the first organ to come into contact with saline soils and salt both reduces root growth and remodels root architecture. When measured on a high temporal scale, salt has been shown to induce multiple root growth phases, namely a stop, quiescent, recovery and homeostasis phase. This project investigates how root architecture is remodeled during salt stress, focusing on high temporal growth dynamics. We aim to answer two research questions:
1) What is the relevance of salt-induced growth phases for overall root architecture?
2) How are these growth dynamics regulated?
