Abstract excerpt
Phosphorus (P) deficiency constrains cereal production, yet improving low-P performance remains challenging because P efficiency depends on rhizosphere mobilisation and internal utilisation. Wild relatives may provide insights into traits weakened during domestication. Here, we compared cultivated barley (Hordeum vulgare; CB) and wild barley (H. spontaneum; WB) to identify traits underpinning low-P tolerance....
