On Friday, February 20, 2026, I gave a seminar at the Shimizu Group at the University of Zurich.
The seminar was titled:
Toward understanding the evolution of self-compatibility in Japanese Arabidopsis halleri

The 12th research meeting of the International Leading Research project “Key-Molecule Network in Plant Reproduction (KEPLR)” was held under the organization of Prof. Takayuki Kohchi.
The meeting featured invited talks by Professor Ueli Grossniklaus, Vice-Director of KEPLR. A total of 24 participants gathered on-site.

The 11th KEPLR Seminar was held on Friday, February 20, 2026, at Nara Institute of Science and Technology (NAIST), organized by Dr. Tetsuya Hisanaga (Junior PI).
Participants included members mainly from the Kansai area — the Kudoh Group, Nasuda Group, and Sato Group — as well as PIs and students from the Higashiyama Group and Tsuchimatsu Group in the Kanto region.
The following presentations were delivered, followed by active discussion:
