Data dump of and supplement to Cardoni et al. (2021) High-Throughput Sequencing of 5S-IGS rDNA in Fagus L. (Fagaceae) reveals complex evolutionary patterns and hybrid origin of modern species. bioRxiv. https://doi.org/10.1101/2021.02.26.433057

This fileset reports intra-/inter-genomic variation of the nuclear-encoded ribosomal 5S region in Fagus (beech). We used a multi-copy, potentially multi-locus marker, the non-transcribed intergenic spacer (IGS) of the 5S nuclear ribosomal DNA, and high-throughput target sequencing to address taxonomy, diversity, and evolution of the F. crenata – F. sylvatica s.str. lineage, and including F. japonica as outgroup. The collected data detail the distribution of divergent main 5S sequence types in the studied species pointing to deep polymorphism (allopolyploid origins), incomplete lineage sorting and repeated phases of reticulation.

The fileset includes:

Supplementary information

Also included are Cardoni et al. (2021) supplementary files S1–S4, which provide extended materials, results and discussion (File S1; PDF); basic information about samples, obtained HTS reads, an annotated lists for the 4,693 variants with an abundance of ≥ 4 summarised also as Pivot tables (File S2, spread-sheet XLSX; optimised for and using Excel autoformatting); graphical representation of the EPA analysis of 4007 5S-IGS variants with a total abundance < 25 (File S3, PDF); and a fully annotated alignment of select-sequence subset in tabulated, graphically enhanced form (File S4, spread-sheet XLSX, includes colouration).
