Roots play an essential role in the acquisition of water and minerals from soils. Measuring crop root architecture and assaying for changes in function can be challenging, but examples have emerged showing that modifications to roots result in higher yield and increased stress tolerance. In this review, we focus mainly on the molecular genetic advances that have been made in altering root system architecture and function in crop plants, as well as phenotyping methods. The future for the modification of crop plant roots looks promising based on recent advances, but there are also important challenges ahead.
根在从土壤中获取水和矿物质方面起着至关重要的作用。测量作物根系结构和分析功能变化具有一定的挑战性，但已经有实例表明，对根的改造可以提高产量和增强对胁迫的耐受性。在这篇综述中，我们主要关注在改变作物根系结构和功能方面所取得的分子遗传进展，以及表型分析方法。基于最近的进展，对作物根系的改造前景广阔，但未来仍面临着重要的挑战。
