图2. 大豆NAM群体RTM-GWAS方法检测到的蛋白质含量QTL等位变异矩阵
横轴表示以蛋白质含量（%）升序排列的种质材料,纵轴表示以增效等位变异频率升序排列的QTL。每行表示一个QTL在不同材料中的等位基因分布,而每列表示一份材料在所有QTL上的等位基因构成。等位基因效应以颜色表示,等位变异效应以颜色表示,即具有暖色的格子代表增效等位变异,而具有冷色的格子代表减效等位变异,颜色的深浅代表等位变异效应的大小

Fig. 2. Graphical representation of QTL-allele matrix of protein content detected in the soybean NAM population
The horizontal axis indicates accessions arranged in ascending order of protein content (%), while the vertical axis indicates QTL arranged in ascending order of their positive allele frequency. Every row indicates the allele distribution among accessions at a QTL, while every column indicates the allele constitution of an accession over all QTLs. Allele effects are expressed in color cells where warm colors indicate positive effects, cool colors indicate negative effects, and color gradient indicates effect size
