Abstract

This work evaluated the roles of the low-molecular-weight organic acids (LMWOAs) from root exudates and the dehydrogenase activity in the rhizosphere sediments of three mangrove plant species on the removal of mixed PAHs. The results showed that the concentrations of LMWOAs and dehydrogenase activity changed species-specifically with the levels of PAH contamination. In all plant species, the concentration of citric acid was the highest, followed by succinic acid. For these acids, succinic acid was positively related to the removal of all the PAHs except Chr. Positive correlations were also found between the removal percentages of 4-and 5-ring PAHs and all LMWOAs, except citric acid. LMWOAs enhanced dehydrogenase activity, which positively related to PAH removal percentages. These findings suggested that LMWOAs and dehydrogenase activity promoted the removal of PAHs. Among three mangrove plants, Bruguiera gymnorrhiza, the plant with the highest root biomass, dehydrogenase activity and concentrations of LMWOAs, was most efficient in removing PAHs.

Allochthonous arbuscular mycorrhizal fungi promote Salix viminalis L.- mediated phytoremediation of polycyclic aromatic hydrocarbons characterized by increasing the release of organic acids and enzymes in soils

Xia Li, Xiaofei Kang, Junzhu Zou, Jiahui Yin, Yuancheng Wang, Ao Li, Xiaodong Ma

Summary: This study aimed to evaluate the effectiveness of arbuscular mycorrhizal fungi (AMF) in enhancing the phytoremediation of polycyclic aromatic hydrocarbons (PAHs)-polluted soil using Salix viminalis and to elucidate the mechanisms induced by AMF. The results showed that AMF inoculation contributed to the dissipation of high-molecular-weight PAHs, such as benzo (alpha) pyrene, and improved the removal efficiency of other PAHs like phenanthrene and pyrene. The research also highlighted the increase in organic acids and soil enzymes induced by AMF, which played crucial roles in PAHs biodegradation.

Type-dependent effects of microplastics on tomato (Lycopersicon esculentum L.): Focus on root exudates and metabolic reprogramming

Ruiying Shi, Weitao Liu, Yuhang Lian, Aurang Zeb, Qi Wang

Summary: The study investigates the effects of different types of microplastics (MPs) on the growth and physiology of tomato plants under hydroponic conditions. It demonstrates that MPs exposure negatively affects tomato growth and leads to changes in physio-biochemical properties, root exudates, and metabolites. Additionally, the study highlights the importance of understanding the toxic effects of various MPs on crops and the need for future risk assessment.

Composition and contribution of Stipa bungeana root exudates to soil organic carbon fractions in the Loess Plateau

Yao Li, Xuan Yang, Xuejuan Bai, Cong Wang, Yimei Huang, Shaoshan An

Summary: Root exudates play a significant role in carbon sequestration in grassland, but their contribution to soil organic carbon (SOC) fractions is not well understood. This study analyzed the composition and content of root exudates in Stipa bungeana and found that esters were the main components. During a 65-day chase period, the contents of SOC and its fractions were higher in the rhizosphere compared to bulk soil. The study also revealed that root exudates had a rapid effect on active organic carbon fractions (MBC and DOC) and humus carbon (HC) in the short term.

The limited exclusion and efficient translocation mediated by organic acids contribute to rare earth element hyperaccumulation in Phytolacca americana

Chong Liu, Dan Sun, Hong-Xiang Zheng, Guo-Bao Wang, Wen-Shen Liu, Yue Cao, Ye-Tao Tang, Rong-Liang Qiu

Summary: This study revealed the mechanism of organic acids in enhancing REE tolerance and accumulation in Phytolacca americana, showing that Yttrium stress stimulated the accumulation of oxalate, malate, and citrate, promoting the transport of Y from roots to shoots. Transcriptome analysis indicated that PaNIP1;2 may play a crucial role in the transport of Y-malate complexes within the plant.

Summary: This study aimed to evaluate the algal species Scenedesmus quadricauda as an efficiency indicator of chemical remediation of PAH-contaminated soils and sediments in Los Barreales Reservoir. Oxidations with FN, PS, or PM were conducted on soil and sediment samples previously contaminated with two types of PAHs. The abundance of S. quadricauda was related to PAH degradation efficacy, residual oxidants, and changes in system pH.

Citric acid can enhance the uptake and accumulation of organophosphate esters (OPEs) in Suaeda salsa rhizosphere: Potential for phytoremediation

Qingzhi Wang, Hongxia Zhao, Tadiyose Girma Bekele, Baocheng Qu, Jingwen Chen

Summary: Root exudates, especially citric acid, play a crucial role in promoting the bioavailability and subsequent accumulation of OPEs in plants. Citric acid can reduce OPEs sorption to soils by decreasing electrostatic interaction, ligand exchange, and hydrophobic force. The increased level of citric acid in rhizosphere soil enhances OPEs mobility and root length, leading to higher accumulation of OPEs in plants.

Comparison of fine root biomass and soil organic carbon stock between exotic and native mangrove

Yasong Zhang, Chenxi Yu, Junjie Xie, Shuntao Du, Jianxiang Feng, Dongsheng Guan

Summary: Despite having higher vegetation and fine root biomass, the exotic Sonneratia apetala does not significantly increase soil organic carbon storage compared to native mangroves. Lower C:N ratio and soil salinity in S. apetala can promote fine root decomposition rate, offsetting the carbon accumulation advantage related to higher fine root biomass. Restoration of mangrove is effective in enhancing soil carbon stock, but the use of exotic S. apetala should be decreased or avoided, especially in Natural Reserves.

Mangrove microbiota along the urban-to-rural gradient of the Cayenne estuary (French Guiana, South America): Drivers and potential bioindicators

Maud Fiard, Philippe Cuny, Lea Sylvi, Cedric Hubas, Ronan Jezequel, Dominique Lamy, Romain Walcker, Amonda El Houssainy, Lars-Eric Heimburger-Boavida, Tony Robinet, Isabelle Bihannic, Franck Gilbert, Emma Michaud, Guillaume Dirberg, Cecile Militon

Summary: The study characterized changes in the structure and diversity of microbial communities of mangroves along the urban-to-rural gradient of the Cayenne estuary, which experience low human impact. Environmental determinants like granulometry, dieldrin concentration, pH, and total carbon content were found to significantly correlate to the microbial communities in these mangroves. Different types of weak anthropogenic pressure, such as organic matter enrichment, dieldrin contamination, and naphthalene contamination, were identified to impact the microbial populations and assemblages in the mangroves.

The synthesis and secretion of key substances in the flavonoid metabolic pathway responding to different nitrogen sources during early growth stages in Robinia pseudoacacia

Yuanli Li, Yongrui Shen, Rui Shi, Ziyi Yang, Yifu Chen, Wen Luo, Gehong Wei, Minxia Chou

Summary: This study analyzed the flavonoid metabolism profiles of Robinia pseudoacacia in response to different nitrogen sources during the early growth stages. The results showed that R. pseudoacacia synthesized and secreted more flavonoids under nitrogen deficiency and exhibited growth-stage-dependent changes in response to different nitrogen sources. The differential flavonoids were significantly enriched in the flavone and flavonol biosynthesis pathway and isoflavonoid biosynthesis pathway. Liquiritigenin, naringenin, apigenin, and kaempferol were identified as key flavonoids involved in the response of R. pseudoacacia to different nitrogen sources.
