Plant root systems are highly plastic in response to environmental stimuli. Improved nutrient acquisition can increase fertilizer use efficiency and is critical for crop production. Recent analyses of field-grown crops highlighted the importance of root system architecture (RSA) in nutrient acquisition. This indicated that it is feasible in practice to exploit genotypes or mutations giving rise to optimal RSA for crop design in the future, especially with respect to plant breeding for infertile soils.
植物根系对外界环境刺激具有很强的可塑性。改善养分吸收可以提高肥料利用率，对作物生产至关重要。最近对田间种植作物的分析强调了根系结构（RSA）在养分获取中的重要性。这表明，在实践中利用产生最佳 RSA 的基因型或突变来进行作物设计是可行的，特别是在针对贫瘠土壤的植物育种方面。
