Plant nanobiotechnology: a new strategy to enhance crop photosynthesis

In crops, photosynthesis is the basis of biomass accumulation and yield formation. With the ever-increasing global population and the increased need to meet the food demand, the ability to increase crop yield has become a pressing concern, especially considering that crop production has been threatened by increased biotic and abiotic stress. Previous studies have evaluated photosynthetic system structure and population photosynthesis based on agronomic and molecular biology. However, these methods require a long study period and a high cost. Therefore, identifying a fast, simple, and cheap strategy to improve plant photosynthesis is crucial for future crop production. Plant nanobiotechnology, as a new interdisciplinary field, provides remarkable insight into plant stress tolerance, chemical delivery, and transgenes. In this review, to provide new insights for future plant nanobiotechnological studies, we examine previous studies on photosynthesis and enhancing photosynthesis through plant nanobiotechnology and suggest possible strategies for increasing photosynthesis.
