CIL:19128

Immuno-gold labeling of corn stunt spiroplasma (CSS, Spiroplasma kunkelii, Class Mollicutes) in sieve elements and other phloem cells of infected maize root tissue. In this image, CSS appears to be crossing a sieve pore in the phloem sieve plate. CIL:12590, 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. Additional images from the same contributors are available in the Library.

本数据集展示感染玉米根组织的筛管分子及其他韧皮部细胞内玉米矮化螺原体（CSS, Spiroplasma kunkelii，柔膜菌纲（Mollicutes））的免疫金标记（Immuno-gold labeling）结果。本图中，CSS似乎正穿过韧皮部筛板上的筛孔。同图像组中的CIL:12590为该图像的未标记版本。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进行生物传播，例如玉米叶蝉（Dalbulus maidis）及D. gelbus（半翅目（Hemiptera）、叶蝉科（Cicadellidae））。螺原体细胞由无细胞壁的单位膜包被，可呈现类球形、多形性或维持丝状/螺旋状形态。CSS可在植物与昆虫宿主内增殖，并可在媒介昆虫取食新宿主植物时随唾液分泌物完成传播。同批供稿者的其他图像可在图库中获取。
