Abstract Phosphorus is of prime importance for growth and vigour during early plant development, hence high seed P content has been regarded as essential for seedling establishment. Julia et al. (2018) challenge this dogma, showing the onset of P uptake by seedlings as early as 3 days after germination and that this is unaffected by seed P concentration. Even more important is that the abundance or expression of P transporter genes in roots is not delayed until seed P reserves have been mobilized. This suggests that breeding for low seed P content could be used as a means of reducing the P requirement of cereals in general.
