BpPIN1的可遗传表观修饰与裂叶桦的叶形相关联
Heritable epigenetic modification of BpPIN1 is associated with leaf shapes in Betula pendula
[目的]欧洲白桦(Betula pendula)的变种裂叶桦(B.pendula'Dalecarlica')叶缘呈掌状开裂,因此具有很高的观赏价值。本研究旨在鉴定裂叶形成的遗传基因及作用机理。[方法]我们进行了混池分离群体分析(BSA-Seq)、基于分子标记的精细定位和SNP等位性检测,以鉴定控制裂叶桦叶形的基因。随后,展开了实时荧光定量PCR,染色质免疫共沉淀测序,全基因组重亚硫酸盐测序,小RNA测序,McrBC-PCR等工作,探究目的基因的表…查看全部>>
The new variety Betula pendula'Dalecarlica'selected from Betula pendula,shows high ornamental values owing to its lobed leaf shape.In this study,to identify the genetic components of leaf shape formation,we performed bulked-segregant analysis(BSA)and molecular marker-based fine mapping to identify causal gene responsible for lobed leaves in B.pendula'Dalecarlica'.The most significant variations associated with leaf shape were identified within the gene BpPIN…查看全部>>
