Summary: This study investigated the structural, developmental and degenerative characteristics of salt glands and the salt secretion mechanisms in the mangrove plant Aegiceras corniculatum. The results revealed the specific features of salt gland cells and their response to salt concentration. Several genes and proteins were identified to be potentially involved in the development and secretion of salt glands. This study provides important insights for further molecular-level studies.

Summary: The study found that the populations of Aegiceras corniculatum are shaped by historical climate changes and sea-level fluctuations, with two main groups identified: Indo-Malayan and Pan-Australasia. Genetic drift in a bottleneck event likely led to the genetic break between the southern and northern South China Sea subgroups of the coastal plant. This case highlights how bottleneck events can promote population subdivision and has implications for other taxa beyond coastal plants.

Summary: This study investigates the molecular mechanisms underlying adaptation to intertidal environments using the pioneer mangrove species Aegiceras corniculatum as a model. The research reveals a whole-genome duplication event, the importance of maintaining cellular environmental homeostasis, and preferential retention of key genes related to salt homeostasis after the duplication. Comparative transcriptomics show that genes upregulated under high-salt conditions are involved in salt transport and ROS scavenging. Additionally, the loss of heme-binding ability in homologues of DELAY OF GERMINATION1 (DOG1) in A. corniculatum may contribute to its crypto-vivipary adaptation.

Summary: The study compared ecosystem organic carbon stocks and soil organic carbon sources between two 12-year-old mangrove sites with different species. Results showed that mangrove vegetation sequestered organic carbon more rapidly than soil pool, with different species impacting carbon sequestration performance. This suggests that attention should be paid to the carbon sequestration features of rehabilitated mangrove forests in future programs.

Summary: The ACR3 genes in arsenic hyperaccumulator Pteris vittata were studied in yeast and tobacco, showing their roles in regulating arsenic translocation and sequestration. PvACR3;2 facilitated AsIII translocation to the shoots and efflux from the roots in tobacco, while PvACR3;3 sequestered AsIII in tobacco root vacuoles.

Summary: This study investigates the methane emission fluxes from different species of trees in coastal mangrove wetlands. The results show that tree stems and pneumatophores are important conduits for methane emissions, with variations between different mangrove communities. The study also highlights the seasonal variations in methane fluxes, but no significant changes in the partitioning of ecosystem methane fluxes between the two seasons were observed.

Summary: Using transcriptome sequencing, the interspecific differences in the molecular response mechanisms of three mangrove plants (Avicennia marina, Aegiceras corniculatum, and Bruguiera gymnorrhiza) under waterlogging stress were studied. The results showed that the plants had different adaptability to waterlogging, and the differentially expressed genes (DEGs) with high folds were classified into four categories: structural regulation, transport, biosynthesis, and protection. A. Marina showed strong regulation ability in the metabolic process, while Ae. corniculatum down-regulated genes related to cell wall regulation or ethylene formation. Additionally, genes involved in alcohol dehydrogenase and lactate dehydrogenase were found to be important in the response of mangrove plants to waterlogging stress.

Summary: This study demonstrates through experiments that microorganisms may facilitate the release of arsenic in sediments in the presence of citric and malic acids, but suppress arsenic mobilisation in the presence of oxalic acid. The results also show significant correlations between iron, manganese, aluminum and trace metal(loid)s (Zn, Pb, Ni, Cu, Cr, Co, Ba, Cd, As). The solution pH is negatively correlated with the solution As content.

Summary: In this study, the release of metals from mangrove surface sediments and Glomalin-related soil protein (GRSP) was investigated. It was found that GRSP can efficiently transfer copper, zinc, lead, and arsenic from sediments to waterfowls. These findings provide new insights into the potential risk of GRSP acting as a metal delivery vehicle in the food chain.

Summary: Coastal reclamation has created additional land for economic development, but also caused pollution and posed threats to sustainable development. This study investigated the distribution patterns, geochemical speciation, and ecological risks of heavy metals in sediment samples from reclaimed and non-reclaimed tidal flats. The results showed higher metal pollution levels in reclaimed sediments, and the presence of Spartina alterniflora could accelerate the deposition and transfer of metal pollutants caused by reclamation.

Summary: This study conducted a field investigation in the abandoned Yellow River Delta to explore the distribution and ecological roles of polycyclic aromatic hydrocarbons (PAHs) in benthic microbial patterns. The study found that PAH levels in the area were relatively low and not dependent on distance, indicating long-term anthropogenic input. Molecular ratios and positive matrix factorization analysis identified three main PAH sources. The benthic microbiome did not show a significant response to PAHs, but certain phyla correlated with PAH source indicators, suggesting that these indicators can serve as environmental indicators for microbial adaptation.

Summary: This study investigates the adsorption behaviors and mechanisms of Pb(II) and Zn(II) ions on glomalin-related soil protein (GRSP). Results show that the adsorption of Pb(II) and Zn(II) on GRSP follows the pseudo second-order model, and the adsorption process is influenced by pollution level, pH value, and GRSP content. The surface structure of GRSP is irregularly blocky or flaky, with metal ions uniformly distributed on its surface. Carboxyl and nitro groups on GRSP act as ligands, forming complexes with divalent metal ions. The interaction between GRSP and metals is mainly through surface complexation. This research provides new insights into the transport and transformation of heavy metals onto GRSP in mangrove sediment and aqueous ecosystems.

Summary: The sorption and desorption behaviors of antibiotics on disposable face masks (DFMs) were investigated. Antibiotics in freshwater showed higher sorption and desorption capacities on DFMs compared to seawater. The sorption processes were related to the zwitterion species of antibiotics, while desorption processes were influenced by solution pH and salinity. The distribution coefficient of certain antibiotics on DFMs was higher than on some microplastics in freshwater systems. The sorption affinity of antibiotics onto DFMs followed the order of TCS > SMX > CIP > TC and was correlated with octanol-water partition coefficient.

Summary: This study investigates the role of disposable face masks (DFMs) as vectors of metal ions in the environment. Aging process promotes metal ion adsorption onto DFMs, mainly due to the presence of oxygen-containing groups. Pristine and aged DFMs have higher adsorption affinity for metal ions with greater electronegativity. Environmental factors like salinity and solution pH affect the adsorption capacity of DFMs. Overall, this study provides insights into the environmental behaviors and risks of DFMs associated with metals.

Summary: This study conducted a bibliometric analysis of global research progress on glomalin-related soil protein (GRSP) through literature review. The results showed that the number of papers on GRSP research has gradually increased since 2010, with a sharp increase in 2019. The United States was the earliest country to conduct GRSP research, while China currently has the largest number of publications. The research focused on the role of AMF and GRSP in soil health and plant health, as well as the contribution of GRSP to soil carbon and its ecological function in mitigating climate change.

Summary: This study describes a feasible extraction and purification method for Glomalin-related soil protein (GRSP) to determine metal(loid)s bound to GRSP. The extraction process does not significantly affect the mineral state of the samples, and potential bias from simultaneous metal release can be eliminated by dialysis. Sodium exchange is found to be a critical process in releasing metal(loid)s, and uncoupling of the Fe-organic framework during extraction may result in the release of organic matter and metal(loid)s. Dialysis can effectively remove most of the metals bound to GRSP.
