Abstract

SOXE transcription factors, including SOX8, SOX9, and SOX10, regulate several developmental events, such as sex determination, chondrogenesis, and neurogenesis. This study systematically identified six SoxE subfamily genes from the turbot (Scophthalmus maximus) genome and transcriptome, including SmSox8a, SmSox8b, SmSox9a, SmSox9b, SmSox10a, and SmSox10b. The duplicates of three SOXE members revealed that SoxE subfamily genes in the turbot underwent significant expansion. Relatively conserved exon-intron structures and intron insertions were detected using genomic structural analysis. Besides, phylogenetic analysis supported the previous classification of the SoxE subfamily. Results of the expression profile revealed that turbot SoxE subfamily genes may be involved in different activities, such as neurogenesis and gonad development. These findings would assist in the understanding of fish SoxE gene subfamily activities and evolution.

鲆鲽类 SoxE 亚家族的分子特征、系统发育和表达谱系

SOXE转录因子，包括SOX8、SOX9和SOX10，调控多种发育事件，如性别决定、软骨形成和神经发生。这项研究从大菱鲆（Scophthalmus maximus）基因组和转录组中系统鉴定了六个SoxE亚家族基因，包括SmSox8a、SmSox8b、SmSox9a、SmSox9b、SmSox10a和SmSox10b。3个SOXE成员的重复序列显示，大菱鲆中的SoxE亚家族基因发生了显著的扩增。通过基因组结构分析，发现了相对保守的外显子-内含子结构和内含子插入。此外，系统发育分析支持了之前对 SoxE 亚家族的分类。表达谱分析结果显示，大菱鲆 SoxE 亚家族基因可能参与不同的活动，如神经发生和性腺发育。这些发现有助于了解鱼类 SoxE 基因亚家族的活动和进化。
