Scanning electron microscope studies demonstrated that cells of Agrobacterium tumefaciens strains attach to cells on the cut surfaces of corn and wheat seedlings and to gladiolus disks. Bacterial cells attached to these monocots in the same manner as they attached to the dicots tested. Of the strains tested, A66 and T37 covered more of the cut surfaces of these monocots in a nonrandom fashion than did cells of other isolates. These bacteria attached to cells of intact monocotyledonous plants and had the greatest affinity for tissues located within the vascular bundles. They attached in large numbers to cells in these areas in all three monocots tested.
扫描电子显微镜研究表明，根癌农杆菌菌株的细胞附着在玉米和小麦幼苗切割表面的细胞以及唐菖蒲切片上。细菌细胞附着在这些单子叶植物上的方式与它们附着在测试的双子叶植物上的方式相同。在所测试的菌株中，A66和T37以非随机方式覆盖这些单子叶植物切割表面的面积比其他分离株的细胞更大。这些细菌附着在完整单子叶植物的细胞上，并且对维管束内的组织具有最大的亲和力。在所有三种测试的单子叶植物中，它们大量附着在这些区域的细胞上。
