Its main features are: algae body as a single cell or even into a variety of groups; cell walls composed of silica and pectin, but also by the structure of the shell and the shell under the combined set of the Cheng, vertical section view was "soap-box"-shaped; in the upper and lower shell surface of the shell are patterns arranged in patterns on both sides of the main mode of symmetry and radial symmetry is divided into two categories, for the classification of the most important basis; be able to campaign Type in the shell has a shell side seam, can not be changed no shell seam types; pigment body sheet or ribbon, 1 or 2, or for multiple small discoid, yellow green or brown, containing chlorophyll a, c, also contains fucoxanthin and silicon A flavin and other photosynthetic pigments; storage material mainly for oil droplets; reproduction mainly for cell division and cell division in diatoms obvious features are: each cell division, resulting from two sub-cells,, only one and the mother cell and so big, the other one is smaller.

其主要特征是:藻体为单细胞或连成各式群体;细胞壁由硅质和果胶质组成,而且在结构上都是由上壳和下壳套合而成,纵断面观呈"肥皂盒"形;在上下壳的壳面上有花纹,花纹排列的方式主要分为两侧对称和辐射对称两大类,为分类上的最重要依据;能运动的种类在壳面都有壳缝,不能动的种类均无壳缝;色素体片状或带状,1个或2个,或为多个小盘状,黄绿色或黄褐色,含叶绿素a、c,还含有墨角藻黄素和硅甲黄素等光合色素;贮藏物质主要为油滴;繁殖方式主要为细胞分裂,硅藻的细胞分裂的明显特点是:每次细胞分裂所产生的2个子细胞中,仅有1个和母细胞等大,另1个则稍小。

In Saintpaulia ionantha, actinomorphic peloria was raised in domesticated cultivation from the zygomorphic wild type.

然而,苦苣苔科的野生型园艺植物非洲堇(Saintpaulia ionantha, African violet)原本野生型的花是两侧对称,但在人择栽培后有反转为辐射对称的变异型出现,这给予我绝佳机会探讨在同一种植物中花部对称性转换的分子机制。

辐射对称 Actinomorphous 辐射状对称,通过结构中央的任一平面都能将其分成互为镜像的两部分。

This suggests persistent expression of SiDIV and ceasing of SiCYC1A and SiCYC1B in late peloric flower stage may generate the actinomorphic flower.

综此推测,变异型的花发育成辐射对称可能是由於开花晚期时SiCYC表现量下降及SiDIV持续表现,造成花发育后期两侧对称性的无法继续维持,而成了辐射对称花形式。
