Supplementary Dataset 2 from the paper "Syntenic cell wall QTLs as versatile breeding tools: intra-specific allelic variability and predictability of biomass quality loci in target plant species"

This dataset contains 100 sets of 91 random QTL regions from the genome of Miscanthus sinensis that mirror the basepair size distribution of 91 QTLs that were found in Miscanthus sinensis through genome-wide association analysis (GWAS) for multiple traits related to biomass (cell wall) quality. The 100 sets of random QTL regions were used in the publication attached to this dataset to perform a permutation analysis to test for co-localization between a set of syntenic QTLs for cell wall quality previously mapped in Miscanthus and the QTLs detected by GWAS (see above). The 100 sets of random QTL regions have been produced in R, by applying the size distribution of GWAS QTLs as constraint for determining the size of random QTLs. Random QTLs could be picked across the whole miscanthus genome, to ensure complete randomness.

本数据集包含100组随机选取的五节芒（Miscanthus sinensis）基因组数量性状位点（Quantitative Trait Locus，QTL）区域，每组包含91个位点；这些随机区域的碱基对长度分布，与通过全基因组关联分析（Genome-Wide Association Study，GWAS）在五节芒中针对多项生物质（细胞壁）品质相关性状鉴定得到的91个QTL的长度分布完全一致。本数据集配套的发表文献中，使用这100组随机QTL区域开展了置换检验分析，用于验证此前在芒草中定位得到的细胞壁品质共线QTL集合与本次GWAS检测到的QTL之间的共定位情况（详见上文）。该100组随机QTL区域通过R语言生成：以GWAS鉴定得到的QTL的长度分布作为约束条件，确定随机QTL的长度；为保证完全随机性，随机QTL可在整个芒草基因组范围内任意选取。
