Recycling amino acids ensures meiosis and seed development.

ABSTRACT

Nitrogen (N) nutrition and meiosis demand large amounts of energy and widely affect crop yield. Recently, Yang and colleagues connected both processes by demonstrating that meiosis initiation depends on the electron-transfer flavoprotein/electron-transfer flavoproteinubiquinone oxidoreductase (ETF/ETFQO) system, whereas meiotic defects of the etfß mutant can be rescued using N supplementation.
