Ren Guodong's team at Fudan University collaborated to reveal a new mechanism for the synergistic regulation of plant photosynthesis by RNA uridylation and SKI complexes

RNA 3' terminal uridylation is an important post-transcriptional modification that is widely found in

The Calvin cycle (also known as the C3 reaction cycle) is the basic pathway

On September 13, 2022, a team of researchers Ren Guodong of Fudan University, in collaboration with Associate Professor Wang Xiaoyan of Beijing Normal University Zhuhai Campus, and Assistant Professor Yu Yu of Shenzhen University, published an online article entitled "Uridylation and the SKI complex orchestrate the Calvin cycle of photosynthesis through RNA" in the Journal of the National Academy of Sciences (PNAS).

By constructing a series of mutants associated with Arabidopsis RNA uridosidases HESO1, URT1 and RNA degradation, the researchers found that the leaves of the heso1 urt1 ski2 mutant were significantly yellowed, the photosynthetic ability was weakened, and the plant growth was slow

Expression abundance of TKL1/2 in heso1 urt1 ski2 mutants and leaf yellowing phenotype

Associate Professor Wang Xiaoyan of Beijing Normal University Zhuhai Campus and Associate Researcher Kong Wenwen of Shenzhen University are the co-first authors
