Fig. 3From: Expression and possible functions of a horizontally transferred glycosyl hydrolase gene, GH6-1, in Ciona embryogenesisIn situ hybridization of the CesA gene in Ciona embryos. Signals for Ciona CesA expression become detectable at A early tailbud (9 hpf), B mid tailbud (10 hpf), C late tailbud I (12 hpf) and D late tailbud II (13.5 hpf). Signals appear in epidermis more ubiquitously than expression of GH6-1. The scale bar in panel A represents 100 μm and applies to all panelsBack to article page
