- n. The presence of an abnormally short tail in some animals as a result of a genetic mutation
Sorry, no etymologies found.
The Pmar1-unresponsive genes wnt8, blimp1, and brachyury (Bra) (circled with hatched black lines) are dispensable for ectopic Pmar1-mediated endomesoderm induction, which probably occurs without inducing ectopic nuclearization of β-catenin in animal blastomeres.
(B) blimp1 expression at 14-16 h p.f. (C) wnt8 expression at 14-16 h p.f. (D) brachyury expression at 20 h p.f. Embryos shown are representative of 100\% of at least 50 embryos in each of three separate experiments in which gfp mRNA was detected in nonvegetal regions.
L. gigantea expressing nodal (red) in a single cell (2c) and brachyury (black) in two cells (3D and 3c). f-h, brachyury (black) is expressed in a symmetrical manner in progeny of
(B) Embryos were treated with either (a-c) DMSO or (g-i) SB (5 μM) and analyzed by WMISH to detect (a and g) brachyury at 18 h, (b and h) blimp1 at 14 h, and (c and i) wnt8 at 14 h.
The gene no tail, a fish homolog of the mouse brachyury or T gene, is expressed in the notochord (Figure
