Technical Note
Visualization of the shell structure of the testate amoeba Paulinella micropora by FE-SEM
Amoebae belonging to the Euglyphida in Rhizaria have shells, which are mostly constructed by self-secreted siliceous scales.

Congratulations to Dr. Tomoko Abe (Deputy Director, Nishina Center, RIKEN) for Receiving the 2021 Wada Memorial Prize entitled “Development of Breeding Methods Using Heavy Ion Beams and Research on Molecular Mechanisms of Chromosomal Rearrangement Mutations”.The linear energy transfer (LET) of heavy ion beams can be controlled by selecting the type and speed of ions. Using this technology, Dr. Abe discovered the LETmax at which the mutation rate is maximized, and found that the larger the LET, the larger the deletion size of DNA and the higher the rate of chromosome rearrangement mutations, and her achievements in perfecting the heavy ion beam breeding method are highly appreciated not only in Japan but also worldwide. She has also developed a mutation detection pipeline for whole genome resequencing and exome analysis, which has made it possible to detect mutations at the whole genome level and to rapidly identify the causative genes of mutants.
