Multi-generational maternal low-nitrogen history leaves a transgenerational microbiome legacy linked to nitrogen uptake in offspring wheat
Multi-generational maternal low-nitrogen history leaves a persistent seed-to-rhizosphere microbiome legacy linked to offspring nitrogen acquisition and uptake in wheat. This legacy can be reduced to a minimal functional synthetic community that reproducibly promotes plant nitrogen uptake, providing a seed-centred framework for microbiome-informed crop improvement under limited nitrogen input.
