Abstract

Given that crop yields are strongly limited by nitrogen, engineering crop plants with self-nitrogen-fertilization capacity holds great promise for sustainable agriculture. Recently, a nitrogen-fixing organelle has been characterized in the unicellular marine microalgae Braarudosphaera bigelowii. Engineering a nitrogen-fixing organelle into the non-nitrogen-fixing crops could benefit both environmental sustainability and global food security.

摘要

鉴于作物的产量受到氮的强烈限制，因此具有自我固氮能力的作物工程具有很大的可持续农业前景。最近，在单细胞海洋微藻 Braarudosphaera bigelowii 中已经鉴定出一种固氮细胞器。将固氮细胞器工程改造到非固氮作物中，可以同时有益于环境可持续性和全球粮食安全。
