Transgenic exploitation of bacterial degradative genes in plants has been considered a favorable strategy for degrading organic pollutants in the environment. The aromatic ring characteristic of these pollutants is mainly responsible for their recalcitrance to degradation. In this study, a

The aim of the study was to determine the quality and quantity of siderophores produced by bacteria isolated from plants' roots. The second aim was to determine the effect of siderophores on plants growth (Festuca rubra L. and Brassica napus L.). The study was carried out using bacteria isolated

Siderophores produced in soil by plant growth-promoting rhizobacteria (PGPRs) play several roles, including nutrient mobilizers and can be useful as plants defense elicitors. We investigated the role of a synthetic mixed ligand bis-catechol-mono-hydroxamate siderophore (SID) that mimics the chemical

Phenols are present in the environment and commonly in contact with humans and animals because of their wide applications in many industries. In a previous study, we reported that uridine diphosphate-glucose-dependent glucosyltransferase PtUGT72B1 from Populus trichocarpa has high activity in

Fungal laccases have been highlighted as a catalytic tool for transforming phenols. Here we demonstrate that fungal laccase-catalyzed oxidations can transform naturally occurring phenols into plant fertilizers with properties very similar to those of commercial humic acids. Treatments of Arabidopsis

The formation of 4-deoxyaurones, which serve as UV nectar guides in Bidens ferulifolia (Jacq.) DC., was established by combination of UV photography, mass spectrometry, and biochemical assays and the key step in aurone formation was studied. The yellow flowering ornamental plant accumulates deoxy

While phytoremediation has been considered as an in situ bioprocess to remediate environmental contaminants, the application of functional endophytic bacteria within plants remains a potential strategy that could enhance the plants' efficiency in phytoremediation. In this study, 219 endophytes were

Previously it has been shown that the caffeoyl coenzyme A O-methyltransferase (CCoAOMT) type enzyme PaF6OMT, synthesized by the liverwort Plagiochasma appendiculatum Lehm. & Lindenb., (Aytoniaceae), interacts preferentially with 6-OH flavones. To clarify the biochemistry and evolution of

The UVR8 photoreceptor in Arabidopsis thaliana is specific for ultraviolet-B (UV-B; 280-315 nm) radiation and its activation leads to a number of UV-B acclimation responses, including the accumulation of flavonoids. UVR8 participates in a signaling cascade involving COP1 and HY5 so that the absence

Bacillus subtilis, a plant growth promoting rhizobacteria (PGPR), induces growth response and protection against pathogenic organisms through colonization and biofilm formation on the Arabidopsis thaliana root surface. In the current investigation, we utilized various Arabidopsis defense pathway

2,4,5-Trichlorophenol, 2,6-dimethylphenol, 3-methylcatechol, phenol, hydroquinone, catechol, and 3,4-dichloroaniline are present in the environment and are risky to humans and animals because of their wide applications in many industries. In this study, a putative uridine diphosphate

Root secretion of coumarin-phenolic type compounds has been recently shown to be related to Arabidopsis thaliana tolerance to Fe deficiency at high pH. Previous studies revealed the identity of a few simple coumarins occurring in roots and exudates of Fe-deficient A. thaliana plants, and left open

Wounding, one of the most intensive stresses influencing plants ontogeny and lifespan, can be induced by herbivory as well as by physical factors. Reactive oxygen species play indispensable role both in the local and systemic defense reactions which enable "reprogramming" of metabolic pathways to

Plant alpha dioxygenases (PADOX) convert fatty acids to 2-hydroperoxy products that are important in plant signaling pathways. The PADOX amino-terminal domain is distinct from that in other myeloperoxidase-family hemoproteins, and the positional specificity and prosthetic group of PADOX distinguish

Salicylic acid (SA) is one of the key signal molecules in regulating plant resistance to diverse pathogens. In Arabidopsis thaliana, it is predominantly associated with resistance against biotrophic and hemibiotrophic pathogens, and triggering systemic acquired resistance. In contrast, the effect of
