Unravelling cluster root development in white lupin

Benjamin Péret
BPMP, équipe Développement et plasticité du système racinaire

White lupin has developed extreme adaptive mechanism to improve phosphate uptake by producing structures called « cluster roots ». They are dense clusters of lateral roots with determinate development and highly specific physiology. I will develop new tools to identify cluster root mutants in white lupin, sequence white lupin genome, perform tissue specific transcriptomics and full molecular characterization of selected genes. This project will also lead me to compare adaptive mechanisms between white lupin and narrow-leafed lupin, a closely related species that does not produce cluster roots. We willalso test whether it is possible to transfer the ability to form cluster roots in this species. Altogether, this project will lead to a major advance in our capacity to understand how plants are ableto sense and respond to their environment and how evolution has selected adaptive developmental mechanisms to improve their capacity to use limited resources.
