The mystery of the unclear biological significance of the ferredoxin/thioredoxin pathway in plants has finally been solved by researchers using CRISPR/Cas9. The researchers show that the pathway is important for light-dependent activation of enzymes, photosynthesis in leaves, and normal growth in plants.The mystery of the unclear biological significance of the ferredoxin/thioredoxin pathway in plants has finally been solved by researchers using CRISPR/Cas9.
