528. 新型自肥小麦:农业的变革
from 知为谁 · host 知为谁
加州大学戴维斯分校的科学家们利用CRISPR基因编辑技术,创造出了一种能够部分自我施肥的新型小麦。这项突破性的研究通过增强小麦根部分泌一种叫做芹菜素的化合物,来刺激土壤细菌形成生物膜,从而保护固氮酶并促进大气氮转化为植物可吸收的养分。这种经过基因工程改造的作物有望显著减少对人工氮肥的需求,从而降低农民的开支、减轻水体污染和温室气体排放。研究团队认为,这项技术可以提高全球食物保障,特别是在贫困地区,并且未来可能推广应用于其他主要的谷类作物。内容来源:https://scitechdaily.com/new-self-fertilizing-wheat-could-transform-farming/
