| 英文摘要 | Recent studies suggest that the cosmopolitan harmful algal bloom (HAB) species Phaeocystis globosa has high genetic diversity, with two major genotypes (sASV_1 and sASV_2) characterized through comparative analysis of P. globosa strains. However, how they differ from each other phenotypically, and how they contribute differentially to bloom development remain unclear. In this study, phenotypic analysis of strains belonging to these two P. globosa genotypes revealed that the average cell size of sASV_2 strains was significantly larger than that of sASV_1 strains. Furthermore, sASV_1 strains contained two characteristic pigments 19 '-butanoyloxyfucoxanthin (But-fuco) and 19 '-hexanoyloxyfucoxanthin (Hex-fuco), while sASV_2 strains contained only But-fuco. Metabarcoding analysis of environmental samples collected during a P. globosa bloom in the Beibu Gulf in 2019 revealed that these genotypes showed different spatiotemporal distribution patterns, suggesting their differential contribution to the P. globosa bloom. And correlation analysis of environmental factors indicated that the responses of P. globosa genotypes to environmental factors showed significant differences. This study confirmed the existence of two P. globosa genotypes with substantial differences in cell sizes and pigment compositions for the first time, and showed that different genotypes may contribute differently during P. globosa bloom development. Results from this study set up a platform for exploring molecular mechanisms underlying genotype-specific P. globosa bloom development, and for monitoring causative strains leading to P. globosa bloom development. |
