Zygnematophytes are the closest algal relatives of land plants. They hold key information to infer how the earliest land plants overcame the barrage of terrestrial stressors, prime of which is osmotic stress. Here, we applied two osmotic stressors on a unicellular and a multicellular representati...

Plant terrestrialization necessitated overcoming a barrage of stressors. Embryophytes (land plants) use an integrated response network to adjust their molecular physiology in response to terrestrial stressors—one of the important stressors is UV irradiance. The zygnematophytes are the closest str...
