转座子微型 Tn7 载体以位点特异性方式插入几种革兰氏阴性细菌的染色体中。在这里,我们展示了 mini-Tn7 作为野油菜黄单胞菌 pv 的单拷贝位点特异性整合载体系统的应用。油菜。在位于 glmS1 下游的 Tn7 附着 (attTn7) 位点检测到 mini-Tn7 转座到细菌基因组中。此外,使用新构建的载体 pBBR1FLP2,其中包含用于对 FLP 识别目标 (FRT) 位点之间的序列进行位点特异性切除的 FLP 重组酶和 sacB 反选择标记,创建了未标记的 mini-Tn7 插入突变体。 Mini-Tn7 插入不会影响受试植物的细菌毒力。 mini-Tn7 和 FLP-FRT 系统在 X. oryzae pv 中也能很好地发挥作用。米霉。
Transposon mini-Tn7 vectors insert into the chromosome of several Gram-negative bacteria in a site-specific manner. Here, we demonstrated the application of mini-Tn7 as single copy site-specific integration vector system for Xanthomonas campestris pv. campestris. The transposition of the mini-Tn7 into the bacterial genome was detected at a Tn7 attachment (attTn7) site located downstream of glmS1. Furthermore, using a newly constructed vector pBBR1FLP2 containing the FLP recombinase for site-specific excision of the sequence between the FLP recognition target (FRT) sites, and a sacB counter selection marker, an unmarked mini-Tn7 insertion mutant was created. Mini-Tn7 insertion did not affect bacterial virulence on the tested plant. The mini-Tn7 and FLP-FRT systems also work well in X. oryzae pv. oryzae.
