Synergistic effects of proteinaceous pheromone and nitrogen starvation on male gametogenesis in the anisogamous volvocine alga Eudorina

Hiroko Kawai‐Toyooka, Makoto Ono, Takashi Hamaji, Hisayoshi Nozaki, Masafumi Hirono

This study shows that proteinaceous pheromones from male Eudorina colonies induce SP formation, with nitrogen starvation enhancing but not requiring this effect.

Chlamydomonas γ-tubulin mutations reveal a critical role for γ-TuRC in maintaining the stability of centriolar microtubules

Yuki Nakazawa, Naoto Kubota, Mao Horii, Akira Noga, Yoshikazu Koike, Hiroko Kawai‐Toyooka, Hideo Dohra, Katsushi Yamaguchi, Shuji Shigenobu, Ken-ichi Wakabayashi, Masafumi Hirono

This study identifies Chlamydomonas γ-tubulin mutations that cause partial loss of protofilaments in centriolar microtubules, highlighting γ-tubulin's role in maintaining triplet microtubule stability.
