Spermine Promotes the Formation of Conchosporangia in Through Superoxide Anions.

The transition from conchocelis to conchosporangia in represents a pivotal stage in its life cycle. As a commercially vital red alga, plays a dominant role in global nori production. The transition governing its sporulation efficiency is pivotal for aquaculture success, yet the underlying regulatory mechanisms, especially their integration with metabolic cues such as polyamines, remain poorly understood.
