Figure 8

Embryonic expression patterns of Sp genes in Parhyale hawaiensis. (a-c) Expression of the Sp1-4 representative at stage S12 (a), stage S19 (b), and stage S22 (c). Staging according to Browne et al. [68]. (a') is the epifluorescence image (Sytox Green staining) of the embryo in a. (d-f) Expression of the Sp6-9 representative at stage S17 (d), stage S18 (e), and stage S23 (f). The arrow in f points to expression in the ventral nervous system. Abbreviations: an1, first antenna; an2, second antenna; md, mandible; mx1, first maxilla; mx2, second maxilla; pe, peraeopods; pl, pleopods; ur, uropods.
