Pyoverdine-specific fluorescence of bacterial cultures was captured at λex=395nm/λex=470nm emission. Out of ~2,000 mutants analyzed, the fluorescence-based screening delivered twelve R569 mutants that lacked pyoverdine-specific fluorescence but retained median-like growth behaviour (Thresholds: -6xMAD fluorescence, >-1xMAD Abs600). For validation, cultures were pre-grown for five days in 50% TSB before sub-culturing into fresh siderophore medium and growth for five additional days. Finally, bacterial culture density (Abs600) was determined and pyoverdine-specific fluorescence of bacterial culture supernatants was captured at λex=410nm/λem=500nm. For comparison between genotypes, fluorescence capacity was calculated by dividing the pyoverdine-specific fluorescence through culture density. +Screening: 1 replicate per mutant +Validation: 3 replicates per WT/mutant diff --git a/assays/R569_mediated_growth_inhibition_of_RsGMI1600/README.md b/assays/R569_mediated_growth_inhibition_of_RsGMI1600/README.md new file mode 100644 index 0000000000000000000000000000000000000000..e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 diff --git a/assays/R569_mediated_growth_inhibition_of_RsGMI1600/dataset/.gitkeep b/assays/R569_mediated_growth_inhibition_of_RsGMI1600/dataset/.gitkeep new file mode 100644 index 0000000000000000000000000000000000000000..e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 diff --git a/assays/R569_mediated_growth_inhibition_of_RsGMI1600/isa.assay.xlsx b/assays/R569_mediated_growth_inhibition_of_RsGMI1600/isa.assay.xlsx new file mode 100644 index 0000000000000000000000000000000000000000..920f024ff73421e29aebc71c932dd741890ed380 Binary files /dev/null and b/assays/R569_mediated_growth_inhibition_of_RsGMI1600/isa.assay.xlsx differ diff --git a/assays/R569_mediated_growth_inhibition_of_RsGMI1600/protocols/.gitkeep b/assays/R569_mediated_growth_inhibition_of_RsGMI1600/protocols/.gitkeep new file mode 100644 index 0000000000000000000000000000000000000000..e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 diff --git a/isa.investigation.xlsx b/isa.investigation.xlsx index 157fd1f0fdd5f106896e00e56d4f8e70a4120e6d..1a1905705011e4884444eaa1bd2982cfc0d09360 100644 Binary files a/isa.investigation.xlsx and b/isa.investigation.xlsx differ diff --git a/studies/mTn5_library_establishment/README.md b/studies/mTn5_library_establishment/README.md new file mode 100644 index 0000000000000000000000000000000000000000..e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 diff --git a/studies/mTn5_library_establishment/isa.study.xlsx b/studies/mTn5_library_establishment/isa.study.xlsx new file mode 100644 index 0000000000000000000000000000000000000000..4a0427e30d58d81cdc5ca9a727b0ff8654a9fd09 Binary files /dev/null and b/studies/mTn5_library_establishment/isa.study.xlsx differ diff --git a/studies/mTn5_library_establishment/protocols/.gitkeep b/studies/mTn5_library_establishment/protocols/.gitkeep new file mode 100644 index 0000000000000000000000000000000000000000..e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 diff --git a/studies/mTn5_library_establishment/protocols/library_protocol.md b/studies/mTn5_library_establishment/protocols/library_protocol.md new file mode 100644 index 0000000000000000000000000000000000000000..bcc436d0a2222f1bb70f3d658a189f55e8d970e6 --- /dev/null +++ b/studies/mTn5_library_establishment/protocols/library_protocol.md @@ -0,0 +1,3 @@ +## Establishment of mini-Tn5 transposon mutant collection in R569 + +Mini Tn5-mutant collection of R569 was established similarly with only minor changes as described below.

Conjugation was carried out as described above in “Conjugation of E. coli and R401 and selection for first homologous recombination eventâ€.

Subsequently, 100 µl 50% glycerol were added to each well and plates were frozen until further processing. The outer rows and columns were left uninoculated as to avoid positional effects in the subsequent forward genetic screen. Resuspended mating patches were stocked at -80 °C in 700-µl aliquots using a final concentration of 25% Glycerol. 1:4 dilutions were plated onto 50% TSA plates supplemented with 120 µg/ml Kan, 50 µg/ml Rifampicin and 50 µg/ml Zeocin and incubated at 25 °C for 48h.
