RAD-seq reads for silver and karelian birch accessions. Betula pendula subsp. pendula

Curly (Karelian) birch is distributed in northern Europe including Finland, Russia (Karelia), Baltic countries, Belarus, Poland, southern Sweden and Norway. This special variety of birch does not form forests, rather building small populations scattered within the north-western part of the silver birch (Betula pendula) distribution. The patterned 'curly' wood of the Karelian birch is used for the manufacturing of highly decorative furniture and architectural panels. In the present study, we analyzed Silver and Karelian birch accessions to study their genetic diversity and detect the genetic regions associated with curly wood formation. In total 192 plant accession were analyzed by means of RAD-seq (Restriction-site associated DNA sequencing).

卷曲桦木（Karelian birch，卡累利阿桦木）分布于北欧地区，包括芬兰、俄罗斯（卡累利阿地区）、波罗的海国家、白俄罗斯、波兰、瑞典南部及挪威。该特殊桦木变种不会形成纯林，仅以零散小种群的形式散布于垂枝桦（Betula pendula）分布区的西北部范围内。卡累利阿桦木带有独特纹理的“卷曲”木纹可用于制作极具装饰性的家具与建筑饰面板。本研究对垂枝桦与卡累利阿桦木的种质材料进行了分析，旨在探究其遗传多样性，并鉴定与卷曲木纹形成相关的遗传区域。本研究共采用限制性酶切位点相关DNA测序（RAD-seq，Restriction-site associated DNA sequencing）技术，对192份桦木种质材料开展了分析。
