Summary: The study showed that pre-treatment with salicylic acid significantly reduced cadmium accumulation in tomato plants and altered cadmium distribution. Salicylic acid induced the composition of the cell wall, increasing cellulose, hemicellulose, pectin, and lignin content, and up-regulated the expression of lignin and cellulose synthase genes while down-regulating pectin methylesterase related genes. Additionally, salicylic acid decreased pectin methylesterase activity to reduce cadmium accumulation in the cell wall and change cadmium partition ratio.

Summary: This field study assessed the baseline conditions of a long-term shooting range in Argentina polluted with lead. The study evaluated the establishment and development of Helianthus petiolaris plants and the efficacy of phytomanagement strategy by analyzing element accumulation, bacterial diversity, and floral water and essential oil yield. The results showed that the roots of Helianthus petiolaris plants had high Pb concentration, but only a small fraction of Pb was translocated to the aerial parts. The presence of Serratia genus in the rhizosphere and the decrease in essential oil yield were significantly associated with soil Pb concentration. No detectable Pb concentration was found in the floral water and essential oil obtained.

Summary: This study characterized the bacterial communities in the seeds and rhizosphere of two Noccaea caerulescens Pb-Zn hyperaccumulator populations in Belgium. The results showed that the seed endophytic community structure was consistent between the two locations, mainly composed of Proteobacteria, while Actinobacteria dominated in the bulk soil. Inoculating Sphingomonas vulcanisoli significantly increased the root length of Arabidopsis thaliana. These findings highlight the importance of selecting the core seed endophytic microbiome and emphasize their precarious symbiotic relationship with the plant and seed.

Summary: Cadmium uptake inhibits plant growth and disturbs physiological processes by affecting the cellular redox environment. Glutathione, an antioxidant, plays a role in redox homeostasis but can be depleted due to its involvement in Cd chelation. This triggers a signaling cascade involving the phytohormone ethylene, organellar stress signaling, and autophagy, leading to acclimation and plant tolerance to Cd stress.

Summary: The study of phytomanagement has seen a significant increase in the past 4 years, but there is limited research on its field application. France is a leading country in using aromatic plants for phytomanaging polluted fields. Applying aromatic plants for degraded land management is a sustainable approach toward circular economy and achieving sustainable development goals. The pollution of trace elements in soils has become a global concern due to their persistence in the environment, which can lead to accumulation in food chains at toxic levels. At the same time, there is a shortage of arable land for growing crops, emphasizing the need for remediation and use of polluted land. Restoration of degraded lands has been recognized as a vital component of UN Sustainable Development Goals (SDGs). This study provides a summary of various sources of trace elements pollution, available biological reclamation and management strategies, and their limitations. Recent advances in phytomanagement approaches using aromatic crops for economic value and revalorizing polluted areas are reviewed. The worldwide application of this strategy in the past decade is illustrated through a choropleth map. Furthermore, the emerging concept of phytomanagement as a restorative and regenerative circular bio-economy is discussed.

Summary: This study evaluated the effects of biochar, clinoptilolite, and elemental sulfur on ammonia and greenhouse gas emissions during cattle slurry storage, as well as on the agronomic quality of the solid and liquid fractions. The results showed that the addition of biochar reduced ammonia emissions by 12% during the first 7 days of storage, and the combination of extra biochar, clinoptilolite, and elemental sulfur further decreased ammonia emissions by approximately 20%. The application of biochar-enriched solid fractions led to a short-term positive priming effect on carbon mineralization.

Summary: Fourteen biochars from seven biomass sources were tested for their long-term Cd2+ removal efficiency. Insect frass, spent peat, and chicken manure-derived biochars showed potential as Cd2+ adsorbents. The pyrolysis temperature played a crucial role in optimizing Cd2+ removal by insect frass and spent peat-derived biochars. The Cd2+ removal by chicken manure biochars, on the other hand, was not affected by the pyrolysis temperature. The kinetics of Cd2+ removal over the course of ten days revealed that insect frass biochar (450 degrees C) showed a gradual increase from 36 to 75 % Cd2+ removal, while chicken manure and spent peat-derived biochar (450 degrees C) already exhibited higher Cd2+ removal (72 - 89 %) after day 1. These findings highlight the importance of considering the long-term Cd2+ removal effect of certain biochars in future soil-based experiments.

Summary: In this study, metal-adapted bacteria that positively influence the growth of Arabidopsis arenosa and Arabidopsis halleri were identified. Bacteria inhabiting the rhizosphere and plant tissues of these hyperaccumulator plants from Zn-Pb-Cd waste heaps were isolated and characterized for their potential plant growth promotion traits and metal concentrations. Taxonomic position was determined using 16S rDNA Sanger sequencing. Among the identified bacterial taxa, the highest taxonomical diversity was found in A. halleri basal leaf endophytes. Most of the investigated strains showed tolerance to heavy metals and exhibited plant growth promotion traits, making them potential candidates for bioremediation.
