植物的隱藏部份——根部，有可能幫助應對人類面臨的挑戰：為不斷增長的世界人口提供糧食，阻止氣候變化，以及以環保的方式提取稀土等珍貴資源。
然而，要做到這一點，植物必須能夠承受乾旱、高溫或洪水侵襲，根部可謂十分關鍵， 它們積極尋找土壤中的營養素，抵禦病原體和毒素等危險。
科學家們現正使用高科技方法研究根部的生長，並以培養出健壯根部的植物為終極目標。

It is precisely the invisible part of plants that has the potential to help with the challenges facing humanity: securing food for a growing world population, stopping climate change, and extracting resources such as rare earths in an environmentally friendly way.
To do this, however, plants must be able to withstand periods of drought and heat and survive floods. Roots are crucial to this. And they actively search for nutrients in the soil and ward off dangers such as pathogens and toxins.
Scientists are now studying root growth using high-tech methods. The goal: to breed stress-resistant seeds for plants with robust roots.
