Seed germination and seedling establishment are two of the most critical phases in plant development. However, the molecular mechanisms underlying the effect of phosphorus on seed germination and post-germinated growth of oilseed rape are unclear so far. Here, we report the role of BnPHT1;4 in seed germination and early seedling development of Brassica napus. | The high-affinity transporter BnPHT1 4 is involved in phosphorus acquisition and mobilization for facilitating seed germination and early seedling growth of Brassica napus
