气孔复合体是植物上部（茎）的典型表皮特化结构。在模式植物拟南芥（Arabidopsis thaliana）中，我们发现在下胚轴（茎和根之间的连接处），气孔按照一种清晰的模式组织，让人想起根表皮的模式。虽然气孔复合体是茎表皮的典型特征，但它们在下胚轴上的模式受参与根表皮模式的基因控制。此外，我们还分离出了不分化气孔复合体的下胚轴表皮细胞的绿色荧光蛋白标记系。在这条线上，根和下胚轴的表皮图案相似。我们的数据支持植物体的径向对称和控制顶/基极性的发育机制之间存在相互作用。(C) 1998学术出版社。
Stomata complexes are epidermal specialized structures typical of the upper aerial part of plants (shoot). In the model plant Arabidopsis thaliana, we show that in the hypocotyl (the junction between the shoot and the root), stomata are organized according to a clear pattern reminiscent of the root epidermis pattern. Although stomata complexes are typical of the shoot epidermis, their pattern on the hypocotyl is under the control of genes involved in root epidermis patterning. Moreover, we have isolated a GFP marker line for the hypocotyl epidermal cells which do not differentiate stomata complexes. In this line the root and the hypocotyl epidermal patterns are similar. Our data support the existence of interactions between developmental mechanisms involved in the control of the apical/basal polarity and the radial symmetry of the plant body. (C) 1998 Academic Press.
