    1. oriT mimic, minimally contains a 126-bp region encompassing three overlapping inverted-repeat sequences (IR1-3), at least one copy of an accessory repeat (AR) and a defined relaxase core region
    2. recently documented “relaxase-in trans” mechanism of conjugative mobilization facilitated by conjugative plasmids

      in Staphylococcus aureus

    1. Mobilizable plasmids carry only the relaxosomal components oriT, a relaxase gene, and one or more nicking auxiliary proteins
    1. IncP plasmids are considered mobilizing plasmids and may transfer other nonconjugative plasmids into new hosts

      Aren't all conjugative plasmids capable of mobilizing? According to the paper -

      IncP, IncN, and IncW are conjugative plasmids that transfer and can be maintained in a diverse array of bacterial hosts

    1. The host range for three of the plasmids (pBF1, pB7, and pB9) was further investigated by the GFP method described above

      Does the host range of transfer go wider than the population where GFP is observed?

      This is my idea of distinctive overlapping categories of host range as venn diagrams.

    2. Consequently, the plasmid donor cells do not express gfp

      Does the leaky expression not hinder the detecting and quantification of transconjugants in epifluorescence microscopy?

    1. mobilizable plasmids, possess their own transfer origin and encode a relaxase but need the help of a conjugative plasmid for their transfer from a donor to a recipient

      Why do mobilizable plasmids encode the mob gene? Can't it be provided in trans by the mobilizing helper strain?

    1. We tested a broad range of Enterobacteriaceae conjugative plasmids for their sensitivity to the growth stage of the donors and identified three distinct regulation types.

    1. Plasmids (IncP/N/W)with 373short and rigid pili only transfer efficiently on solid surfaces, unlike those with longand flexible 374pili (IncF/H/T/J),capable of transferring equally well in liquidand on solid surfaces[35,36]

      Plasmid group vs pili length

    1. For English, telling the difference between instantaneous and continuative verbs is easy, because we seldom, if ever, use “be +ing” form for the former. For Japanese, however, the situation is complicated, as ていますcan be used with both kinds of verb.

      There is no way to tell the continuity of a verb by simply looking at it. One must understand the concept before knowing the full meaning when paired with ています.
