Sorghum root-system classification in contrasting P environments reveals three main rooting types and root-architecture-related marker–trait associationsDOI: 10.1093/aob/mcx157 Keywords: Root-system architecture, root-system classification, sorghum, phosphorus scarcity, genome-wide association studies Abstract: Roots facilitate acquisition of macro- and micronutrients, which are crucial for plant productivity and anchorage in the soil. Phosphorus (P) is rapidly immobilized in the soil and hardly available for plants. Adaptation to P scarcity relies on changes in root morphology towards rooting systems well suited for topsoil foraging. Root-system architecture (RSA) defines the spatial organization of the network comprising primary, lateral and stem-derived roots and is important for adaptation to stress conditions. RSA phenotyping is a challenging task and essential for understanding root development
