The integument of an insect segment displays two distinct pattern features which are based on different properties of the constituent epidermal cells. Normally, the uniform orientation of epidermal cell polarities ("polarity pattern") is strictly correlated with the sequence of differentiated cells ("differentiation pattern"). Here it is reported that in the integument of the cotton bug Dysdercus epidermal cells can adopt orientations that do not correlate with the pigmentation pattern and which are not compatible with the gradient model. The results indicate that different features of a composite pattern can be independently controlled.
昆虫体节的体表呈现出两种不同的图案特征,这两种特征基于组成表皮细胞的不同特性。通常,表皮细胞极性的均匀取向(“极性图案”)与分化细胞的序列(“分化模式”)严格相关。在此报道,在棉红蝽的体表,表皮细胞可以采用与色素沉着模式不相关且与梯度模型不兼容的取向。结果表明,复合图案的不同特征可以独立控制。
