Fig. 2From: Whole genome level analysis of the DEATH protein superfamily in sheep (Ovis aries) and their coordination relationship in regulating lactationPhylogenetic classification of four subfamilies of DEATH proteins of different species. These phylogenetic trees were constructed through the neighbor-joining method with 1,000 bootstrap replicates based on DD, CARD, DED, and PYRIN protein sequences from five organisms (three vertebrates: Ovis aries, Gallus gallus, and Danio rerio; and two invertebrates: Octopus bimaculoides and Trichoplusia ni). These different colors are only used to indicate that one phylogenetic tree can be divided into several major clades, and the same colors do not suggest that these clades in different trees have common characteristicsBack to article page
