Phosphorus (P) is one of the three macronutrients for plants.
Because of its low mobility and high fixation in soils, low P
availability is a worldwide constraint for crop productivity.
Molecular biology provides great opportunities to improve P
efficiency in plants. However, transgenic plants cannot be
commercialized before integrating all the knowledge on
bottlenecks for improving P efficiency of crops/pastures. This
review intends to summarize the main strategies of
bioengineering to improve P efficiency of crops/pastures,
including conventional and molecular assisted breeding,
identification and application of key genes for biotech plants. It
highlights recent advances in the understanding of improving P
efficiency through the integration of bioengineering with P
fertilization and cultivation management.
