Historical climate changes significantly influenced the phylogeographical patterns of intertidal macroalgae. The brown alga Colpomenia sinuosa was common in warmer waters worldwide, providing an ideal model for genetic diversity and distribution research. C. sinuosa has abundant biomass in the coastal South China Sea, which is a well-known hotspot on marine biodiversity. Here, we analyzed its population structure and demograph...

MAS (marker assisted selection) is useful for cultivar development in the lower plant Saccharina japonica . In this study, 167 screened SSR markers and 125 individuals were used to construct a S.japonica genetic linkage map with 27 linkage groups and a total Haldane length of 2069 cM. Constructed linkage groups were aligned with assembled pseudo-chromosomes of S. japonica genome sequences (NCBI: MEHQ00000000) and anchored to 2...

Long-distance drifting of seaweeds driven by ocean currents is an ideal model for exploring population-level genetic connectivity and phylogeographic structure. In the Indo-Pacific convergence region, we integrated phylogeographic and ocean current data and Lagrangian particle simulations to explore how the ocean currents contributed to the biogeographical patterns and population genetic connectivity of Sargassum polycystum ....
