An Insight into the Mechanism Underlying
Summary
A research group led by Professor Akitoshi Iwamoto of Kanagawa University, in collaboration with Assistant Professor Suzuka Kikuchi of Yamaguchi University, Professor Sachihiro Matsunaga and Professor Munetaka Sugiyama of the University of Tokyo, has focused on the phenomenon known as "high-ploidy syndrome" in which growth is suppressed when the genome is highly polyploidized, and analyzed it in the model plant Arabidopsis thaliana. The results showed that both cell proliferation and cell volume increase are greatly suppressed in higher-order polyploids, and that one of the causes is "chromosome polytenization" in which increased chromosomes stick to each other for some reason.
Polyploidization in plants is actually used to improve crop production. Elucidation of the mechanism of the "high-ploidy syndrome" is expected to lead to the establishment of a more efficient method for producing highly productive crops. The research results were published in the OXFORD ACADEMIC "Journal of Experimental Botany" on July 5, 2024 (UK time).
