摘      要：Macroalgae are multicellular,aquatic autotrophs that play vital roles in global climate maintenance and have diverse applications in biotechnology and eco-engineering,which are directly linked to their multicellularity ***,their genomic diversity and the evolutionary mechanisms underlying multicellularity in these organisms remain *** this study,we sequenced 110 macroalgal genomes from diverse climates and phyla,and identified key genomic features that distinguish them from their microalgal *** for cell adhesion,extracellular matrix formation,cell polarity,transport,and cell differentiation distinguish macroalgae from microalgae across all three major phyla,constituting conserved and unique gene sets supporting multicellular *** genes show phylum-and climate-specific expansions that may facilitate niche ***,our study reveals genetic determinants of convergent and divergent evolutionary trajectories that have shaped morphological diversity in macroalgae and provides genome-wide frameworks to understand photosynthetic multicellular evolution in aquatic environments.
