试验发现未冲洗的柑桔溃疡病菌的细菌细胞优先粘着于柑桔叶片组织的受伤部分而不是完整的叶片表面。经冲洗的柑桔溃疡病菌的细菌细胞以及缺乏产生体外多糖的菌落突变体的未冲洗细胞,几乎不能粘着于柑桔叶片的受伤组织。受伤的柑桔叶片组织以D一葡糖胺、链霉蛋白酶以及pH值低的柠檬酸缓冲液进行预处理时,未冲洗细胞的粘着作用便受到抑制。未冲洗细菌细胞的粘着作用在以各种异寄主组织的叶碟进行观察时,
It was found that the bacterial cells of unwashed Citronella canker preferentially adhered to the injured part of the citrus leaf tissue rather than to the intact leaf surface. Bacterial cells of the washed Citrus canker, as well as unwashed cells lacking colonies producing in vitro polysaccharides, barely adhered to the injured tissue of the citrus leaves. Injured citrus leaf tissue with D-glucosamine, pronase, and low pH citrate buffer pretreatment, the adhesion of unwashed cells was inhibited. Adhesion of Non-Flushing Bacterial Cells When viewed in leaf disks of various heterologous host tissues,
