The transition from the vegetative to sexual reproductive phase is the most dynamic change to occur during algal life cycle. Elucidating the regulatory mechanisms of the sexual reproduction in red algae appears to be important to the understanding of eukaryotic evolution, because red algal group represents an ancient lineage. Recent studies suggest that the ethylene precursor 1-aminocylopropane-1-carboxylic acid (ACC) acts as a signaling molecule independent from ethylene in the regulation of gametogenesis and tolerance to oxidative stress in Neopyropia and Pyropia (Bangiaceae). ACC signaling through alterations to the redox state induces the expression of the RWP1 encoding a homolog to RWP-RK family involved in sexual reproduction in green lineage, as well as vesicular-trafficking and cell-division-related genes. The further research could provide exciting insights into not only the regulation of the red algae life cycle but also the evolutionary perspective of the mechanisms on various biological processes such as the relationship between redox signaling and cell differentiation.
