Fig. 5: Characterisation of chitin binding peritrophin-A gene and pif gene in Chrysomallon squamiferum.
From: The Scaly-foot Snail genome and implications for the origins of biomineralised armour
a Phylogenetic analysis of chitin binding peritrophin-A and pif genes with names in red indicating genes from the Scaly-foot Snail, and domain architecture of the specific genes displayed on the right of names (purple indicates chitin binding peritrophin-A and blue indicates von Willebrand factor type A). b In situ hybridization of chitin binding Peritrophin-A in scales. c Boxplot showing the expression level of chitin binding peritrophin-A in five different tissue types including mantle, scale-secreting epithelium, gill, oesophageal gland (OG), and foot. The box depicts first to third quartile with whiskers indicating maximum and minimum expression levels, and the centre line refers to the median. Source data are provided as a Source Data file. d In situ hybridization showing the expression of pif gene in mantle. e Boxplot showing the expression level of pif in five different tissues types. Within the Boxplot, the centre line refers to the median, and the boxplot depicts the first to the third quartile, with the whiskers indicating maximum and minimum expression levels.
