The Xenopus Brachyury-like Xbra3 gene is a novel T-box gene that is closely associated with Xenopus Brachyury. The expression pattern of Xbra3 during development is similar to that of Xbra. During gastrulation Xbra3 is expressed in the marginal zone, with a gradient of increasing expression from ventral to dorsal. In the early neurula stage Xbra3 is expressed in the notochord and posterior mesoderm, but by the tailbud stage its expression is restricted to the forming tailbud and the posterior portion of the notochord.
非洲爪蟾类Brachyury基因Xbra3是一种与非洲爪蟾Brachyury密切相关的新型T盒基因。Xbra3在发育过程中的表达模式与Xbra相似。在原肠胚形成期,Xbra3在边缘区表达,从腹侧到背侧表达呈梯度增加。在神经胚早期,Xbra3在脊索和后中胚层表达,但到尾芽期,其表达局限于正在形成的尾芽和脊索后部。
