CIL:19125

Electron micrograph of corn stunt spiroplasma (CSS, Spiroplasma kunkelii, Class Mollicutes) in sieve elements and other phloem cells of infected maize roots. CIL:12587, 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.

本图像为感染玉米根系筛管及其他韧皮部细胞内的玉米矮化螺原体（corn stunt spiroplasma, CSS, Spiroplasma kunkelii，柔膜菌纲（Mollicutes））的电子显微照片。同图像组中的CIL:12587为该图像的无标注版本。CSS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实现生物传播，例如玉米矮化叶蝉（Dalbulus maidis）与D. gelbus（半翅目（Hemiptera），叶蝉科（Cicadellidae））。螺原体细胞仅由单位膜包裹，无细胞壁，其形态可呈近球形、多形性，或维持丝状或螺旋状。CSS可在植物与昆虫宿主体内增殖，并可在介体昆虫取食新宿主植物时，随唾液分泌物完成传播。该投稿者的图像馆藏中可获取相关图像。
