| 摘要 | Background As a unique sulfated polysaccharide, fucoidan is an important component of cell wall in brown seaweeds. Its biochemical properties are determined by the positions and quantity of sulfate groups. Sulfotransferases (STs) catalyze the sulfation process, which transfer the sulfuryl groups to carbohydrate backbones and are crucial for fucoidan biosynthesis. Nevertheless, the structures and functions ofSTsin brown seaweeds are rarely investigated. Results There are a total of 44 STgenes identified from our genome and transcriptome analysis ofSaccharina japonica, which were located in the 17 scaffolds and 11 contigs. TheS. japonica STgenes have abundant introns and alternative splicing sites, and five tandem duplicated gene clusters were identified. Generally, theSTgenes could be classified into five groups (Group I similar to V) based on phylogenetic analysis. Accordingly, the ST proteins, which were encoded by genes within the same group, contained similar conserved motifs. Members of theS. japonica STgene family show various expression patterns in different tissues and developmental stages. Transcriptional profiles indicate that the transcriptional levels of more than half of theSTgenes are higher in kelp basal blades than in distal blades. Except forST5andST28,mostSTgenes are down-regulated with the kelp development stages. The expression levels of nineST geneswere detected by real-time quantitative PCR, which demonstrates that they responded to low salinity and drought stresses. Conclusions Various characteristics of theSTsallow the feasibilities ofS. japonicato synthesize fucoidans with different sulfate groups. This enables the kelp the potential to adapt to the costal environments and meet the needs ofS. japonica growth. |
