Hidden genomic evolution in a morphospecies—The landscape of rapidly evolving genes in Tetrahymena
Fig 5
T. thermophila LRR genes can be sorted into 3 groups with different properties.
(a) LRR genes are sorted into 3 groups based on the presence or absence of 90-bp exons and on MAC CRS masking. (b) Ratios of species-specific to conserved genes among the 3 groups of LRR genes. Two asterisks indicate a significant difference between 2 groups (chi-squared test, p < 1 × 10−5). (c) Exon length distributions of the 3 groups of LRR genes. (d) Intron length distributions for the 3 groups of LRR genes. Colors in (c) and (d) are as in (b). CRS, consensus repeat sequence; LRR, leucine-rich repeat; MAC, macronucleus.
