摘要翻译:
提出了一个生命系统模式形成的模型。这种模式是通过两条信号通路的顺序相互作用而实现的。当高斯曲率'k'进入时,模式与(厚)上皮片变化的耦合给出。该模型为眼睛、触角、四肢和翅膀等器官提出了一种新颖的点状放置。在植物模式的情况下,从茎中长出的“叶”被预测在一个尚未发现的“主调节基因”的控制下,类似于动物的情况,当动物身体的各种长出通常伴随着“无远端”(Dll)基因的激活时。

英文摘要:
A model of pattern formation in living systems is presented. The pattern is achieved by the sequential interaction of two signaling pathways. The coupling of the pattern to the (thick) epithelial sheet changes is given, when the Gauss curvature'K'enters. The model suggests a novel point-like placement for organs such as eyes, antennae, limbs, and wings. In the case of plant patterns, 'leaf' outgrowths from a stem are predicted to be under the control of a yet to be discovered "master regulatiory gene", analogous to the animal case, when various outgrowths from the animal body are generally accompanied by activation of the 'distal-less' (Dll) gene.
