Table S1. Candidate gene lists for Populus salicinoid phenolic glycosides

An Excel file of candidate genes from QTL intervals for the salicinoid phenolic glycosides, salicortin and HCH-salicortin in a backcross population of hybrid cottonwoods (Populus fremontii x P. angustifolia. Each worksheet in the file contains the gene lists for a particular interval. In cases where QTL intervals overlapped on the same chromosome, the +/- 1.3Mb interval pertains to the furthest/nearest point from the chromosome start (i.e. co-occurring peaks at 1Mb and 2Mb would have an interval ranging from 0Mb to 3.3Mb). Each table includes gene name, start and end positions in bp, description. QTL peaks from our study, shared SSR makers from Caseys et al. (2015), and candidate genes are all shown in red text.本数据集为一份Excel文件，包含美洲杨（Populus fremontii）与窄叶杨（Populus angustifolia）杂交得到的回交群体中，与水杨苷类酚苷（salicortin与HCH-salicortin）相关的数量性状基因座（Quantitative Trait Locus, QTL）区间的候选基因。该文件的每个工作表对应一个特定QTL区间的基因列表。若同一染色体上的QTL区间发生重叠，则±1.3Mb的区间将覆盖距染色体起始位置最远或最近的位点：例如，若1Mb与2Mb处存在共现峰值，则对应区间范围为0Mb至3.3Mb。每张数据表均包含基因名称、以碱基对（base pair, bp）为单位的起始与终止位置，以及基因功能描述。本研究中的QTL峰值、Caseys等人（2015）共享的简单序列重复（Simple Sequence Repeat, SSR）标记，以及候选基因均以红色文本标注。
