Strigolactones Control Root System Architecture and Tip Anatomy in Solanum Lycopersicum L. Plants under P Starvation.

ABSTRACT: The hormones strigolactones accumulate in plant roots under phosphorus (P) shortage, inducing variations in plant phenotype. In this study, we aimed at understanding whether strigolactones control morphological and anatomical changes in tomato (Solanum lycopersicum L.) roots under varying P supply. Root traits were evaluated in wild-type seedlings grown in high vs low P, with or without exogenous strigolactones, and in wild-type and strigolactone-depleted plants grown first under high vs no P, and then under high vs no P after acclimation on low P. Exogenous strigolactones stimulated primary root and lateral root number under low P. Root growth was reduced in strigolactone-depleted plants maintained under continuous P deprivation.
