Multi-dimensionality in plant root traits:progress and challenges

Plant roots,the major agent for water and nutrient acquisition,are fundamental for plant growth,evolution and ecosystem services that human beings depend on(Bardgett et al.2014;Weigelt et al.2023).Nutrient acquisition can be depicted by a wealth of traits of absorptive roots,the few terminal root branch orders with primarily developed tissues(Guo et al.2008;McCormack et al.2015).
