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.

A conserved RWP-RK transcription factor VSR1 controls gametic differentiation in volvocine algae

Sa Geng, Takashi Hamaji, Patrick J. Ferris, Minglu Gao, Yoshiki Nishimura, James Umen

This study identifies VSR1, a conserved RWP-RK transcription factor, as a key regulator of gametic differentiation in volvocine algae, revealing a mechanism involving homodimers and heterodimers with MID.
