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 flavoprotein:ubiquinone oxidoreductase (ETF/ETFQO) system, whereas meiotic defects of the etfβ mutant can be rescued using N supplementation.

Keywords: ETFQO system; metabolic checkpoint; nitrogen; remobilization of compounds; reproductive development.
