The rates of increase in yield of the main commercial crops have been steadily falling in many areas worldwide. This generates concerns because there is a growing demand for plant biomass due to the increasing population. Plant yield should thus be improved in the context of climate change and decreasing natural resources. It is a major challenge which could be tackled by improving and/or altering light-use efficiency, CO2 uptake and fixation, primary metabolism, plant architecture and leaf morphology, and developmental plant processes. In this review, we discuss some of the traits which could lead to yield increase, with a focus on how natural genetic variation could be harnessed. Moreover, we provide insights for advancing our understanding of the molecular aspects governing plant growth and yield, and propose future avenues for improvement of crop yield. We also suggest that knowledge accumulated over the last decade in the field of molecular physiology should be integrated into new ideotypes.
在全球许多地区，主要商业作物的产量增长率一直在稳步下降。这引发了人们的担忧，因为随着人口增长，对植物生物质的需求也在不断增加。因此，在气候变化和自然资源减少的背景下，需要提高作物产量。这是一项重大挑战，可以通过提高和/或改变光利用效率、二氧化碳吸收与固定、初级代谢、植物结构和叶片形态以及植物发育过程来应对。在本综述中，我们讨论了一些可能导致产量增加的性状，重点是如何利用自然遗传变异。此外，我们为增进对控制植物生长和产量的分子方面的理解提供了见解，并提出了提高作物产量的未来途径。我们还建议，过去十年在分子生理学领域积累的知识应整合到新的理想型中。
