(a) RMSD calculation from the superimposition of Cα atoms of Rap3T structures in complex with peptides SRGHTS, RGHTS, RRGHTA, and RRGHTAS. RMSD were calculated from individual monomers (lower) and dimers (upper). Number of atoms used in RMSD calculation is showed between parenthesis. (b) Superposition of 4 Rap3T-Peptide complexes with different pheromone variants in monomeric state RRGHTAS (blue), RRGHTA (pink), RGHTS (light green), and SRGHTS (orange). (c) Superposition of dimers for the 4 Rap3T complexes with peptides RRGHTAS (blue), RRGHTA (pink), RGHTS (light green), and SRGHTS (orange)., pbio.3002744.s004.tiff, Peer reviewed

Disc diffusion assay for testing fosfomycin resistance of WT AB5075, ΔcavA deleted mutant, vfr::Tn transposon mutant and their complemented derivative strains (ΔcavA+vfr and vfr::Tn+vfr respectively), as well as ΔcavA mutant overexpressing vfr (ΔcavA+vfr). CAMH agar inoculated with each corresponding strain and having a fosfomycin (50 μg) disc were assessed after 24 h at 37°C. Representative images (A) and the measured zone of inhibition in millimetres (B) are shown. Data represents the averages ± SD of biological triplicates. ns p>0.05, *p<0.05, ***p<0.001, ****p<0.0001 –One-Way ANOVA with Dunnet post-hoc test (B). All controls used are presented in S10B Fig, Peer reviewed

Cyclic di-GMP levels measured using CensYBL-Ab biosensor in ΔcavA mutant with low cAMP and ΔcavA+cavA complemented strain with high cAMP levels (A) as well as vfr::Tn mutant (B) compared to WT AB5075. Deletion of cavA reduced c-di-GMP levels by 66% (A) while disruption of vfr decreased them by 49% (B). Cultures were diluted in LB broth supplemented with apramycin (100 μg/ml) and biosensor expression was induced with anhydrotetracycline (50 ng/ml). Harvested cells were resuspended in sterile PBS and YFP and mCherry fluorescence signals were measured. The average normalised fluorescence (YFP/mCherry) ± SD from three independent biological repeats is presented. Data was analysed using One-Way ANOVA with Tukey post-hoc test (A) and Unpaired t-test (B) (* p<0.05, ** p<0.01). Strains harbouring empty miniTn7 were used as controls (S9B Fig)., Peer reviewed

Biofilm formation (A), EPS production (B) and twitching motility (C) of vfr::Tn transposon mutant AB07171, its complemented strain vfr::Tn+vfrWT, strains overexpressing vfr in the WT (WT+vfr) and ΔcavA backgrounds (ΔcavA+vfr) compared to AB5075 WT. In addition, vfr::Tn mutant was complemented with vfr variant harbouring two modified residues (T138A and T139W) in the cAMP binding site (vfr::Tn+vfrT138A,T139W). A—Biofilm formation microtiter assay was used as described above and biofilms were grown in LB broth for 24 h at 37°C shaking. Growth of the strains was assessed and strains harbouring empty miniTn7 were used as control. B—Images of colonies on Congo red agar for EPS production assessment were taken 5 days post-inoculation. C—Motility was assessed using soft agar at 48 h as described in the materials and methods section. Data including all controls is presented in S6 Fig. All experiments were repeated three independent times. Bar graphs present averages ± SD. *p<0.05, **p<0.01, ***p<0.001, ****p<0.0001—One-Way ANOVA with Dunnet (A) and Tukey (B & D) post-hoc tests, Peer reviewed

El trabajo realizado ha dado lugar al desarrollo y patente de un equipo basado en técnicas de confinamiento de campo que resuelve los problemas presentados por las generaciones anteriores de equipos basados en la misma familia de técnicas. Este equipo persigue poder realizar la monitorización continua de la corrosión en estructuras reales. El equipo es capaz de determinar la velocidad de corrosión de la armadura, además de la resistividad del hormigón y el potencial de corrosión de la armadura, tres parámetros clave a la hora de poder estimar el periodo de propagación dentro de la vida útil de las estructuras. La medida de la velocidad de corrosión y de la resistividad se realiza a través de dos nuevas técnicas orientadas a superar las limitaciones observadas en los corrosímetros actuales. La principal ventaja del sistema desarrollado es que evalúa directamente la propia armadura embebida sin necesidad de instalar o generar una sección de armadura como electrodo de trabajo. Esto permite una instalación no invasiva del sensor, ya que se coloca cerca de la armadura a evaluar sin perturbar sustancialmente las condiciones físico-químicas del entorno. De esta forma se garantiza una evaluación representativa y en condiciones reales de trabajo de los elementos de hormigón armado. Además, el sensor cuenta con diseño versátil que permite su instalación tanto en obra nueva (embebido) como en obra ejecutada (en superficie). Este sistema pretende ser una solución realmente pionera en el caso de la monitorización de estructuras existentes, y más en especial para la evaluación de armaduras activas en elementos pretensados o postesados donde no es posible alterar en absoluto el sistema acero-hormigón evaluado., Peer reviewed

A—Cyclic di-GMP levels in WT AB5075, WT overexpressing constitutively active DGC gene pleD* (WT+pleD*) and WT with empty miniTn7 used for the strain construction. This demonstrates the activity of the modified CensYBL-Ab in detecting the elevated c-di-GMP levels in the WT+pleD* strain. The inactive CensYBL*-Ab biosensor was used to demonstrate that the increase in the signal was due to the changing c-di-GMP levels. B–Cyclic di-GMP levels in cavA related strains compared to the parental WT AB5075. The empty miniTn7 was used as control which demonstrates the empty vector did not have an effect on the c-di-GMP levels in the WT or the deleted ΔcavA mutant. ns p>0.05, ** p<0.01, **** p<0.0001—Two-Way ANOVA (A) and One-Way ANOVA (B) with Tukey post-hoc test., Peer reviewed
