Relationships, domain architecture and gene structure of AIG genes in B. glabrata. a. A maximum likelihood (ML) phylogenetic tree of AIG1 domain sequences, with bootstrap values of 50 and greater noted with black shapes on the nodes (square 90–100, circle 70–89, triangle 50–69). For those AIG genes with dual-AIG1 domains, labels of “_1” and “_2” were added to the corresponding gene ID to differentiate the first and the second AIG1 domains. The tree topology revealed five clades (I-V) with well-supported bootstrap values (> 75), with two separate individual branches appearing among the five clades. b. Domain architectures of representative protein sequence of each AIG gene are listed. The featured domains include AIG1, coiled-coil, TMi (transmembrane domain from inside to outside of a membrane), TMo (transmembrane domain from outside to inside of a membrane), and other special functional domains: DD-CARD (death domain CARD type), DD-Fas (death domain Fas type), Hint (hint/hedgehog), armadillo (ARM)-type fold and Pkinase (protein kinase). c. Gene structures corresponding to representative transcripts of AIG genes were shown with exon, intron and untranslated region (UTR) in different colors
