SBP转录因子在植物生长发育、信号转导、胁迫应答等方面起着重要的调控作用,由SBP基因家族基因编码。为探究银杏SBP基因家族的特征及表达模式,采用高通量测序技术对银杏的叶、花芽和胚珠进行转录组测序,鉴定SBP基因家族成员,并进行基因定位、miRNA156靶位点预测、进化关系以及表达模式的分析。本研究共鉴定到15个银杏SBP基因家族成员,该基因家族在染色体上分布较分散,编码产物长度差异较大,其中有5个成员具有miRNA156靶位点。蛋白保守基序分析显示,除GbSBP5、GbSBP12、GbSBP14不具有完整的SBP保守结构域外,其余成员编码蛋白均具有SBP保守结构域(包括2个锌指结构和1个核定位信号)。聚类分析表明,...

The SBP gene family is composed of the members which specifically encode the SBP transcription factors. This family plays an important role in regulating plant growth and development, signal transduction, and stress response. To explore the characteristics and expression patterns of SBP gene family in Ginkgo biloba, high-throughput sequencing technology was used to obtain the transcriptome data of leaves, flower buds and ovules of Ginkgo biloba. A total of 15 members of the SBP gene family of Ginkgo biloba were identified in this study. The ide...
