“…aminovorans genome, is responsible for the utilization of almost 40% of 54 carbon sources which were found to be utilized by the strain (by BIOLOG arrays and growth experiments in minimal media), including all C1 compounds. This distinguishes pAMV1 from other known catabolic plasmids, which usually determine the utilization of particular groups of carbon compounds (e.g., aromatic compounds) (Sayler et al , ; Pemberton and Schmidt, ).…”

Plasmids play an important role in the adaptation of bacteria to changeable environmental conditions. As the main vectors of horizontal gene transfer, they can spread genetic information among bacteria, sometimes even across taxonomic boundaries. Some plasmids carry genes involved in the utilization of particular carbon compounds, which can provide a competitive advantage to their hosts in particular ecological niches. Analysis of the multireplicon genome of the soil bacterium P. aminovorans JCM 7685 revealed the presence of an extrachromosomal replicon pAMV1 (185 kb) with a unique structure and properties. This lifestyle-determining plasmid carries genes facilitating the metabolism of many different carbon compounds including sugars, short-chain organic acids and C1 compounds. Plasmid pAMV1 contains a large methylotrophy island (MEI) that is essential not only for the utilization of particular C1 compounds but also for the central methylotrophic metabolism required for the assimilation of C1 units (serine cycle). We demonstrate that the expression of the main serine cycle genes is induced in the presence of C1 compounds by the transcriptional regulator ScyR. The extrachromosomal localization of the MEI and the distribution of related genes in Paracoccus spp. indicate that it could have been acquired by HGT by an ancestor of P. aminovorans.

“…The pages of biodegradation history unveil pioneering bacterial strains, such as Pseudomonas putida, bearing the degradative camphor (CAM) plasmid, which boasts the capacity to orchestrate the oxidation of terrant and camphor and encode genes responsible for the degradation of 2,4-dichlorophenoxyacetic acid (2,4-D), a widelyused herbicide [68,69]. A plasmid, pJP4, isolated from Ralstonia eutropha strain JMP134, has been recognized for harboring a broad spectrum of degradation genes that enhance the breakdown of organochlorines, 2,4-D, and 3-chlorobenzoate [70]. Additionally, the genes ptrD, ptrA, ptrB, ptrC, phtAa, phtAb, phtAc, and phtAd, sourced from Arthrobacter keyseri (plasmid 12B), are instrumental in phthalate degradation [71].…”

Globally, pest-induced crop losses ranging from 20% to 40% have spurred the extensive use of pesticides, presenting a double-edged sword that threatens not only human health but also our environment. Amidst various remediation techniques, bioremediation stands out as a compelling and eco-friendly solution. Recently, the phytomicrobiome has garnered increasing attention as endophytic microbes, colonizing plants from their roots, not only foster plant growth but also enhance the host plant’s resilience to adverse conditions. Given the persistent demand for high crop yields, agricultural soils often bear the burden of pesticide applications. Biodegradation, the transformation of complex pesticide compounds into simpler forms through the activation of microbial processes and plant-based enzymatic systems, emerges as a pivotal strategy for restoring soil health. Manipulating the phytomicrobiome may emerge as a viable solution for this purpose, offering a native metabolic pathway that catalyzes pollutant degradation through enzymatic reactions. This review delves into the pivotal role of phytomicrobiomes in the degradation of diverse pesticides in soil. It explores contemporary innovations and paves the way for discussions on future research directions in this promising field.

Catabolic Plasmids

Abstract: Catabolic plasmids are circular, accessory DNA elements present in the cytoplasm of many soil bacteria. They confer on their host the ability to degrade and recycle complex, naturally occurring and synthetic molecules, including a vast array of environmental pollutants.
