Plants use nitrogen inefficiently. A study @nature shows that, in maize, the plastoglobule droplets within chloroplast organise key nitrogen-fixation enzymes, supercharging nitrogen use. The findings could be relevant to growing crops using less fertiliser.

Chloroplast plastoglobules act as nitrogen-assimilation hubs in maize, with key enzymes enhancing nitrogen-use efficiency and offering new strategies for developing high-yield, sustainable crops.
