Figure Caption

Fig. 3 The enlarged LsDh phenotype of sec61al1^c163 is independent of the parapineal organ. (A) In wild-type larvae, the parapineal organ (gfi-1, blue) is found adjacent to the left LsDh (kctd12.1, red). (A′) Likewise, sec61al1^c163 mutants possess a single parapineal organ on the left side of the brain. (B) The pineal complex (consisting of the pineal and parapineal, labeled by otx5) is similar in WT and (B′) sec61al1^c163 mutant larvae. (C) Compared to an non-injected control (NIC), with a parapineal organ on the left side of the brain (dashed oval), (D) disruption of parapineal organ formation using a tbx2b antisense morpholino causes a reduction in the size of the left LsDh (kctd12.1). (C′, D′) However, in sec61al1^c163 mutants, reduction of the parapineal organ has no effect on the size of the LsDh on either the left or right side. All views are dorsal. Panels A, C, D = 96 hpf; B = 72 hpf. Parapineal indicated by black arrowheads A–C′. Scale bar = 10 μm.
