Resumen de: WO2025255275A2
By engineering genetic traits associated with photosynthesis in plants, transgenic plants with increased crop yield can be generated, which will ultimately lead to increased food production in the field. To obtain beneficial genetic traits for enhanced photosynthesis, accelerated evolution is applied under salt stress in a cyanobacteria species, Synechococcus elongatus PCC 7942, by conditionally suppressing its mismatch repair system. Through high-throughput screening for biomass accumulation and sucrose production, it is discovered that specific amino acid changes in the pre-Dl protein of Photosystem II (PSII), encoded by the psbA genes, can improve efficiency of photosynthesis under salt stress, as well as pathogen resistance. Next, the same amino acid changes were made in Arabadopsis and proved that photosynthetic efficiency (measured via growth rate) is also increased in this model vascular plant.
