CIL:19124

Electron micrograph of corn stunt spiroplasma (CSS, Spiroplasma kunkelii, Class Mollicutes) in sieve elements and other phloem cells of infected maize leaves. CIL:12586, from the same image group, is an unlabeled version of this image. CSS is a wall-less procaryote that causes corn stunt disease and is biologically transmitted by some leafhopper species, e.g. Dalbulus maidis and D. gelbus (Hemiptera, Cicadellidae). Spiroplasma cells are limited by a unit membrane with no cell wall. They can be quasi-spherical, pleiomorphic or maintain a filamentous/spiral form. CSS multiplies in both plant and insect hosts and is transmitted with salivary secretions during feeding of the vector on new host plants.

本图像为感染玉米叶片的筛管分子与其他韧皮部细胞内玉米矮化螺原体（corn stunt spiroplasma, CSS，Spiroplasma kunkelii，柔膜菌纲（Mollicutes））的电子显微照片。同图像组内的CIL:12586为该图像的无标注版本。该螺原体为无细胞壁原核生物，可引发玉米矮化病，可通过部分叶蝉物种进行生物传播，例如玉米残跳虫（Dalbulus maidis）及D. gelbus（半翅目，叶蝉科）。螺原体细胞仅由单位膜包被，无细胞壁，其形态可呈近球形、多形性，或维持丝状/螺旋状。该螺原体可在植物与昆虫宿主体内增殖，并在介体昆虫取食新宿主植物时随唾液分泌物传播。该供稿者的其他图像可在图库中获取。
