Fig. 4From: Deep whole-genome resequencing sheds light on the distribution and effect of amphioxus SNPsExamples of protein structure variation brought by SNPs. For each example, raw SNP-absent structure is marked by green and SNP-present structure is marked by blue. SNPs are located in the red-squared regions. Structures with SNPs are aligned to original structures for comparison, where overlapping green–blue regions can be recognized as unchangedBack to article page
