Hydrogen peroxide (H 2 O ) is a strong oxidant capable of oxidizing cysteinyl thiolates, yet only few cysteine-containing proteins have exceptional reactivity toward H . One such example the prokaryotic transcription factor OxyR, which controls antioxidant response in bacteria, and specifically rapidly reduces In this study, we present crystallographic evidence for -sensing mechanism -dependent structural transition Corynebacterium glutamicum OxyR by capturing reduced -bound structures...
Abstract Pine needles are specialized leaves bearing distinctive anatomical features whose function is to minimize water loss. At the molecular level, needle specialization expected lead heterogeneity in cell wall (CW) composition. By immunohistochemical analysis of CW epitopes maritime pine ( Pinus pinaster ) needles, we described variability composition all tissues, discussing its possible relationship with function. Cells transport, tracheids, transfusion and endodermis, together...
The Mycobacterium tuberculosis rv2466c gene encodes an oxidoreductase enzyme annotated as DsbA. It has a CPWC active-site motif embedded within its thioredoxin fold domain and mediates the activation of prodrug TP053, thienopyrimidine derivative that kills both replicating nonreplicating bacilli. However, mode action actual enzymatic function in M. have remained enigmatic. In this study, we report Rv2466c is essential for bacterial survival under H2O2 stress. Further, discovered lacks...
The cell wall (CW) is a dynamic structure extensively remodeled during plant growth and under stress conditions, however little known about its roles the immune system priming, especially in crops. In order to shed light on such process, we used Phaseolus vulgaris-Pseudomonas syringae (Pph) pathosystem priming capacity of 2,6-dichloroisonicotinic acid (INA). first instance confirmed that INA-pretreated plants were more resistant Pph, which was line with enhanced production H2O2 primed after...
Abstract The mechanisms underlying susceptibility to and defense against Pseudomonas syringae (Pph) of the common bean (Phaseolus vulgaris) have not yet been clarified. To investigate these, 15-day-old plants variety Riñón were infected with Pph transcriptomic changes at 2 h 9 post-infection analysed. RNA-seq analysis showed an up-regulation genes involved in defense/signaling h, most them being down-regulated suggesting that inhibits reprogramming plant. This trend was also observed...
Common bean (Phaseolus vulgaris) is attacked by several pathogens such as the biotrophic gamma-proteobacterium Pseudomonas syringae pv. phaseolicola. To study P. phaseolicola-bean interaction during first stages of infection, leaf discs a susceptible cultivar Riñón were infected with pathogenic Using this experimental system, we tested six new putative wall-associated kinase (WAK) receptors, previously identified in silico. These vulgaris WAKs (PvWAKs) showed high protein sequence homology...
Halo blight disease of beans (Phaseolus vulgaris L.), caused by the bacterium Pseudomonas syringae pv. phaseolicola (Pph), is responsible for severe losses in crop production worldwide. As current agronomic techniques used are not effective, it necessary to search new ones which may prevent common bean. In this study, we challenged four plant-based preparations (PBPs), with no other uses, as they come from industrial waste (grapevine pomace (RG) and hop residue (RH)) or wild plants (Urtica...
Abstract The susceptibility of common bean varieties to Pseudomonas syringae pv. phaseolicola (Pph) has been well-documented. However, the molecular mechanism that drives this not clarified yet. In an attempt understand process, 15-day-old plants, variety riñón, were infected with Pph analyze transcriptomic changes during first steps infection (at 2 and 9 h). RNA-seq analysis showed upregulation defense-and signaling-related genes at 2h, most them being downregulated 9h, suggesting would...
