Abstract

The phytosphere population densities of Pseudomonas fluorescens SBW25EeZY6KX (lacZX aph xylE) carrying pQBR103 (Hg(supr) Tra(sup+), 330 kbp) declined significantly relative to plasmid-free populations after seed inoculation. As the sugar beet plants matured, ca. 100 days after planting, simultaneous selections for plasmid-carrying hosts were observed in the phyllospheres and rhizospheres of field-grown plants. The recovery of these populations to densities indistinguishable from the densities of plasmid-free inocula (4 x 10(sup5) CFU/g in the rhizosphere) demonstrates that phytosphere-associated plasmids confer a specific fitness advantage to host bacteria.

摘要

携带 pQBR103（Hg(supr) Tra(sup+), 330 kbp）的荧光假单胞菌 SBW25EeZY6KX(lacZX aph xylE)在种子接种后，其在植物根际的种群密度明显低于无质粒种群。随着甜菜植株的成熟，大约在种植后 100 天，田间生长的植物根际和叶际中同时出现了对携带质粒的宿主的选择。这些种群的恢复密度与无质粒接种物的密度（根际为 4 x 10(sup5)CFU/g）无法区分，这表明与植物叶际相关的质粒赋予了宿主细菌特定的适应优势。
