Macroalga aquaculture in China dates back to 960–1279 AD and currently represents an impressive 60% of global production (Blouin et al., 2011; FAO, 2022). Among the various aquacultural algae, Neopyropia yezoensis holds the highest economic value per unit, with an annual production exceeding 2.2 million tons (FAO, 2022). Presently, the predominant breeding techniques for N. yezoensis include natural seed selection and artificial mutation breeding. However, these methods are characterized by inefficiency and inadequacy for the development of high-quality varieties. Furthermore, the reproductive characteristics of N. yezoensis, marked by hermaphroditism and self-fertilization (Blouin et al., 2011; He et al., 2019), pose formidable challenges to hybrid breeding. Therefore, there is a pressing need for improved breeding strategies for N. yezoensis. The intricate life cycle of N. yezoensis, featuring a haploid gametophytic macro-stage and a diploid sporophytic micro-stage (Blouin et al., 2011; He et al., 2019), sets it apart from terrestrial organisms, highlighting its unique position in biological evolution. Neopyropia yezoensis is not only an economically important species; its unique properties give it the potential to be a model organism. For example, it can complete its life cycle in the laboratory, has fewer chromosomes, a compact genome, and exhibits rapid growth (He et al., 2019; Wang et al., 2020). Despite its importance, the potential of N. yezoensis as a model species h...
