Description

Root system architecture (RSA) influences the effectiveness of resources acquisition from soils but the genetic networks that control RSA remain largely unclear. We used rhizoboxes, X‐ray computed tomography, grafting, auxin transport measurements and hormone quantification to demonstrate that Arabidopsis and Medicago CEP (C‐TERMINALLY ENCODED PEPTIDE)‐CEP RECEPTOR signalling controls RSA, the gravitropic set‐point angle (GSA) of lateral roots (LRs), auxin levels and auxin transport. We showed...[Show more]
