Scatter Plot from Scientific Research

PCA projection of 5-mer frequency vectors for centromeric satellite repeats (CentBd or CentBs) on PC1(first principal component) and PC2 (second principal component) from different assembled Brachypodium genomes. Each point represents an individual copy of satellite and colored according to the sub/genomes. Light red, cyan, light green, and purple points represent satellites from Bd21-CEN, Bst99-CEN, BhD, and BhS subgenome of IBd483-CEN genomes. Box plots on the top or right of PCA projection show the overall distribution of PC1 and PC2 scores between different sub/genome groups ( T -test, ** P < 0.01).
