近日，美国加州大学旧金山分校Julian I. Schroeder与加州大学河滨分校Julia Bailey-Serres等研究人员合作讨论了提高作物产量的遗传策略。2019年11月7日，国际学术期刊《自然》发表了这一综述论文。

研究人员表示，当前的农作物产量预期不足以在2050年之前养活全世界的人口。由于病虫害和病原体的变化、降水、热浪和其他极端天气因素造成的气候压力限制了产量，必须实现更大和更稳定的农作物产量。

研究人员讨论了植物科学解决绿色革命后农业挑战的潜力，并探索了在气候变化中增强可持续作物生产和恢复力的新兴战略。加速作物改良必须利用自然进化的性状和机制理解推动的改造工程，从而产生确保未来收成所需的弹性生产系统。

Abstract: The current trajectory for crop yields is insufficient to nourish the worlds population by 20501. Greater and more consistent crop production must be achieved against a backdrop of climatic stress that limits yields, owing to shifts in pests and pathogens, precipitation, heat-waves and other weather extremes. Here we consider the potential of plant sciences to address post-Green Revolution challenges in agriculture and explore emerging strategies for enhancing sustainable crop production and resilience in a changing climate. Accelerated crop improvement must leverage naturally evolved traits and transformative engineering driven by mechanistic understanding, to yield the resilient production systems that are needed to ensure future harvests. Genetic strategies for improving the yield and sustainability of agricultural crops, and the resilience of crops in the face of biotic and abiotic stresses contingent on projected climate change, are evaluated.
