Additional file 9 of Chromatin loop anchors contain core structural components of the gene expression machinery in maize

Additional file 9. replicate 1 chromatin loop anchor annotation and counts for each feature listed below. (seqid) Chromosomal assignment for loop anchor; (start) (end) Coordinates (in bps) of start and end, respectively, of chromatin loop anchor; (locus) name and loop assignment of anchor; (bare) presence or absence of any of the features listed below on anchor (0 = at least one feature present; 1 = no feature present). The following features are annotated: (ef) (uf) expressed (ef) or unexpressed (uf) gene with nearest open chromatin peak >2Kbps away from gene; (en3) (un3) expressed (en3) or unexpressed (un3) gene with nearest open chromatin peak <2Kbps downstream from gene; (en5) (un5) expressed (en5) or unexpressed (un5) gene with nearest open chromatin peak <2Kbps upstream from gene; (eo) (uo) expressed (eo) or unexpressed (uo) gene with nearest open chromatin peak overlapping with gene; (mp) open chromatin peak overlapping an anchor; (mpfe) open chromatin peak overlapping an anchor but with the nearest expressed gene >2Kbps away from the peak.

补充文件9：重复1的染色质环锚点（chromatin loop anchor）注释信息，以及下述各特征的计数结果。
（seqid）染色质环锚点的染色体归属信息；
（start）（end）分别为染色质环锚点起始与终止位置的坐标（单位：碱基对bps）；
（locus）锚点的名称及其环归属信息；
（bare）锚点是否存在下述任意特征的标记（0表示锚点上至少存在一个特征，1表示锚点无任何特征）。
本次注释的特征如下：
（ef）（uf）指最近的开放染色质峰（open chromatin peak）与基因间距大于2千碱基对的表达（ef）或未表达（uf）基因；
（en3）（un3）指最近的开放染色质峰位于基因下游且间距小于2千碱基对的表达（en3）或未表达（un3）基因；
（en5）（un5）指最近的开放染色质峰位于基因上游且间距小于2千碱基对的表达（en5）或未表达（un5）基因；
（eo）（uo）指最近的开放染色质峰与基因区域存在重叠的表达（eo）或未表达（uo）基因；
（mp）与锚点区域存在重叠的开放染色质峰；
（mpfe）与锚点区域存在重叠，但该峰最近的表达基因与其间距大于2千碱基对的开放染色质峰。
