摘要	Blue light is one of the important factors that influences Saccharina japonica growth and development. Circular RNAs (cir-cRNAs) are a class of abundant endogenous stable RNAs that play vital roles in many biological activities. To explore the blue light-mediated regulation of circRNAs, the transcript profiles of circRNAs in response to blue light (RB), white light (RW) and dark (RD) were characterized in the sporophytes of S. japonica using rRNA-depleted circular RNA sequencing and bioinformatics analysis. In total, 1768 circRNAs were identified in sporophytes, and 969 (54.81%) were derived from exons. Enrichment analysis showed that the parental genes of S. japonica circRNAs were involved in spliceosome, RNA transport, protein processing in the endoplasmic reticulum and endocytosis pathways. In total, 37 and 14 differentially expressed cir-cRNAs were identified in the RB vs. RD and RB vs. RW comparisons, respectively. The sja-circ-000945, sja-circ-000944, sja-circ-000486 and sja-circ-000518 were differentially expressed in both the RB vs. RD and RB vs. RW comparisons, which indicating that they may play vital roles in blue light-mediated signal transduction. Based on the circRNA-microRNA-mRNA network analysis, sja-circ-000518 and sja-circ-000486 were related to sporophyte growth and development. In addition, sja- circ-000518 was involved in signal transduction by competing for binding sites in novel-m3940-3p with both CBL-interacting protein kinase 31 and phosphatidylinositol 4 -phosphate 5-kinase. In conclusion, circRNAs may function as posttranscrip-tional regulators in blue light-mediated growth and development of S. japonica. Our study provides an understanding of the regulation of circRNAs from the perspective of circRNA-related competitive endogenous RNAs in the brown macroalgae.
