The occurrence of annulate lamellae (AL) in differentiating phloem of Sonchus oleraceus (Compositae) singly infected with sowthistle yellow vein virus (SYVV) and doubly infected with a combination of SYVV and beet yellow stunt virus is documented by electron microscopy. Cell types in which AL were found were immature sieve elements and phloem parenchyma cells. AL were found only in cells that also contained SYVV particles although a direct association between the virus and AL was not apparent. The substructure of the AL and the relationships between the AL and the nuclear envelope and endoplasmic reticulum are similar to those reported in other descriptions of this organelle in the literature. This report appears to be the first one concerning the association of AL with a plant virus disease.
通过电子显微镜记录了在单独感染苦苣菜黄脉病毒（SYVV）以及同时感染SYVV和甜菜黄矮病毒组合的苦苣菜（菊科）分化韧皮部中环状片层（AL）的出现情况。发现有AL的细胞类型为未成熟筛管分子和韧皮薄壁细胞。虽然病毒与AL之间没有明显的直接关联，但仅在也含有SYVV粒子的细胞中发现了AL。AL的亚结构以及AL与核膜和内质网之间的关系与文献中关于该细胞器的其他描述相似。本报告似乎是关于AL与植物病毒病关联的首篇报道。
