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.
氮（N）营养和减数分裂需要大量的能量，并广泛影响作物产量。最近，Yang 及其同事通过证明减数分裂的起始依赖于电子传递黄素蛋白/电子传递黄素蛋白：泛醌氧化还原酶（ETF/ETFQO）系统，将这两个过程联系起来，而 etfβ 突变体的减数分裂缺陷可以通过补充 N 来挽救。
