Abstract
Poplar (Populus) is a genus of woody plants of great economic value. Due to the growing economic importance of poplar, there is a need to ensure its stable growth by increasing its resistance to pathogens. Genetic engineering can create organisms with improved traits faster than traditional methods, and with the development of CRISPR/Cas-based genome editing systems, scientists have a new highly effective tool for creating valuable genotypes. In this review, we summarize the latest research data on poplar diseases, the biology of their pathogens and how these plants resist pathogens. In the final section, we propose to plant male or mixed poplar populations; consider the genes of the MLO group, transcription factors of the WRKY and MYB families and defensive proteins BbChit1, LJAMP2, MsrA2 and PtDef as the most promising targets for genetic engineering; and also pay attention to the possibility of microbiome engineering.

Ecophysiological response of Populus alba L. to multiple stress factors during the revitalisation of coal fly ash lagoons at different stages of weathering. FRONTIERS IN PLANT SCIENCE 2024; 14:1337700. [PMID: 38269133 PMCID: PMC10805861 DOI: 10.3389/fpls.2023.1337700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Accepted: 12/21/2023] [Indexed: 01/26/2024]
Abstract
The enormous quantities of fly ash (FA) produced by thermal power plants is a global problem and safe, sustainable approaches to reduce the amount and its toxic effects are still being sought. Vegetation cover comprising long-living species can help reduce FA dump-related environmental health issues. However, the synergistic effect of multiple abiotic factors, like drought, low organic matter content, a deficit of essential nutrients, alkaline pH, and phytotoxicity due to high potentially toxic element (PTE) and soluble salt content, limits the number of species that can grow under such stressful conditions. Thus, we hypothesised that Populus alba L., which spontaneously colonised two FA disposal lagoons at the 'Nikola Tesla A' thermal power plant (Obrenovac, Serbia) 3 years (L3) and 11 years (L11) ago, has high restoration potential thanks to its stress tolerance. We analysed the basic physical and chemical properties of FA at different weathering stages, while the ecophysiological response of P. alba to multiple stresses was determined through biological indicators [the bioconcentration factor (BCF) and translocation factor (TF) for PTEs (As, B, Cr, Cu, Mn, Ni, Se, and Zn)] and by measuring the following parameters: photosynthetic efficiency and chlorophyll concentration, non-enzymatic antioxidant defence (carotenoids, anthocyanins, and phenols), oxidative stress (malondialdehyde (MDA) concentrations), and total antioxidant capacity (IC50) to neutralise DPPH free radical activity. Unlike at L3, toxic As, B, and Zn concentrations in leaves induced oxidative stress in P. alba at L11, shown by the higher MDA levels, lower vitality, and reduced synthesis of chlorophyll, carotenoids, and total antioxidant activity, suggesting its stress tolerance decreases with long-term exposure to adverse abiotic factors. Although P. alba is a fast-growing species with good metal accumulation ability and high stress tolerance, it has poor stabilisation potential for substrates with high As and B concentrations, making it highly unsuitable for revitalising such habitats.

Abstract
Soil contamination with heavy metals and metalloids is a global concern nowadays. Phytoremediation is an eco-friendly, cost-effective, and sustainable way of mitigating such contamination by utilizing the plants' ability to accumulate, sequester, and stabilize elements. Biomass-producing plants may outperform hyperaccumulators in terms of total elemental removal and offer more cost-effectiveness through their usable biomass. Ipomoea carnea is a wild plant in the Asian region. It is resilient, spreads rapidly in a wide range of soil conditions, and has a high potential for biomass feedstock. In this work, we have tested this plant species for its growth performance and accumulation characteristics of Cr and As. In a pot experiment, the plants could easily grow from rootless stem segments in 2 weeks when garden soils are treated with 100-500 ppm of Cr and 20-300 ppm of As. Plant growth reduction was little at the moderate level of these elements, with a significant accumulation of elements in 45 days. Within this time, in the stems and leaves, the Cr concentrations were found to be 49 and 39 ppm, respectively, when treated with 500 ppm of Cr, whereas the As concentrations were obtained as 83 and 28 ppm, respectively, for the treatment with 300 ppm of As. To estimate the biomass production potential, the plant was grown with a density of 80,000 per ha under normal field conditions (without metal stress). At the harvest, the plants consisted of 80% stems, 11% leaves, and 9% belowground portions on a dry weight basis. The dry weight of stems, leaves, and belowground parts was 31.3%, 17.9%, and 23.7%, respectively. Overall, the estimated biomass was 25.8 Mg/ha/year from three harvests. The ability to regrow from the basal part makes it useful for continuous sequestration of toxic elements over multiple harvests. Our results show that I. carnea could lower Cr and As from contaminated soils and potentially a phytoremediation candidate considering accumulation rate and high amount of usable biomass production.

Abstract
Populus deltoides is one of the most favored cash crops in northern India. Thus, accurate identification of pathogens affecting P. deltoides is a critical step in finding or developing effective control measures. In June 2020, symptoms of a leaf blight disease were observed on P. deltoides trees planted at Forest Research Institute, Dehradun, India. Calonectria-like fungal isolates were consistently isolated from the infected leaf samples. Morphological features coupled with phylogenetic analysis of combined partial actin (act), calmodulin (cmdA), histone (his3), translation elongation factor 1-alpha (tef1) and β-tubulin (tub2) gene regions of two fungal isolates confirmed a novel species, which is described and illustrated here as Calonectria populi sp. nov. Symptoms similar to those observed in natural conditions were caused by both the isolates on P. deltoides clone AM109 in detached leaf assays and glasshouse inoculation experiments. Finally, Koch's postulates were established by re-isolation and re-identification of the pathogen from the inoculated leaves. This work is the first to confirm a new leaf blight disease of P. deltoides caused by C. populi sp. nov. in India and worldwide.

Shahidi A, Khashei-Siuki A, Bagheri H, Afshin A. Field study of irrigation strategies with treated wastewater and saline water on heavy metal accumulation in barley grain. WATER ENVIRONMENT RESEARCH : A RESEARCH PUBLICATION OF THE WATER ENVIRONMENT FEDERATION 2023; 95:e10943. [PMID: 37864288 DOI: 10.1002/wer.10943] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 09/08/2023] [Accepted: 10/13/2023] [Indexed: 10/22/2023]
Abstract
This study examines the effects of three irrigation regimes with a combination of saline water and treated wastewater on the accumulation of heavy metals in barley grains. A field experiment was designed as a split-split plot arrangement in a randomized complete block design, in which treatments were different irrigation regimes (50%, 70%, and 100% full irrigation) and irrigation water types (saline water [SW], treated wastewater [TW], mixed water resources [MWR], and alternative irrigation [AI]). After cultivation and harvesting of the barley crop, the grain yield, 1000-grain weight, and contents of heavy metals in the grains were measured. The grain yield was enhanced by TW alone, MWR, and AI to 12.8%, 5%, and 9.5% under 70%-deficit irrigation; and 58.3%, 21.7%, and 8.7% under full irrigation, respectively. Based on the guidelines for safe limits of heavy metals in edible plants and livestock feed, the barley grains were safe for livestock and toxic for humans. The trend of heavy metal contents in the grains was Fe > Zn > Pb > Cu ≥ Cr > Cd. Irrigation with SW compared with TW increased Fe, Cu, Zn, Pb, Cd, and Cr contents in the grains to 11.75%, 10.97%, 5.22%, 19.15%, 3.45%, and 9.21%, respectively. The amounts of toxic elements of Cd and Pb were maximized by using MWR, whereas the Cr content in the grain was maximized by using AI. There were no significant difference in the metal uptake by the grains among all irrigation regimes in any irrigation water resource. However, compared with the other irrigation regimes, the full irrigation resulted in lower Zn, Cu, and Cd contents, whereas the 50%-deficit irrigation led to lower Pb and Cr contents in the grains. Therefore, irrigation with TW is recommended based on the grain yield, whereas AI is suggested due to lower Cu, Pb, and Cd contents in the grain, and MWR is recommended due to lower Cr content. Furthermore, full and 50%-deficit irrigation regimes are recommended to, respectively, maximize grain yield and minimize the toxic metal contents in the grain. PRACTITIONER POINTS: Mixed saline water and treated wastewater and alternative irrigation enhanced grain yield. Saline water versus treated wastewater increased the grain heavy metal contents. Alternative irrigation decreased Fe, Cu, Pb, and Cd amounts in the grain. Grain Cu content had strong relationship with irrigation regime. 50%-deficit irrigation minimized Pb and Cr contents in the grain.

ENVIRONMENTAL MONITORING AND ASSESSMENT 2023; 195:1193. [PMID: 37698692 DOI: 10.1007/s10661-023-11806-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 08/30/2023] [Indexed: 09/13/2023]
Abstract
The present study investigated the bioaccumulation and translocation of mercury (Hg) and chromium (Cr) in Yunyan 87 flue-cured tobacco (Nicotiana tabacum) and assessed the influence of soil pH on the metal uptake by plant organs at the field scale. The study was conducted in 4 different regions selected from Sichuan Province, China: Guangyuan, Luzhou, Panzhihua, and Yibin. The results revealed that Hg highly contaminated Yibin soils at 0.29 mg kg-1 and by Cr at 147 mg kg-1, which is above the permissible limit. The levels of Hg in tobacco plant organs were predominantly in the order of leaves > root > stem. The overall trend for Cr contents in tobacco organs was in the order of root > leaves > stem. The results of an index of bioaccumulation (IBA) and translocation factor (TF) showed that the values observed in Panzhihua and Guangyuan tobacco leaves were generally higher, despite the low levels of soil contamination. The linear mixed model (LMM) demonstrated that the log of Hg IBA in tobacco organs was likely to decrease with soil pH increase, whereas the log of Cr IBA only decreased in the root but gradually increased in the aerial parts with soil pH increase. The total random variation in the log of metals' IBA due to regions indicated that for Hg, 33.42% of the variation was explained by regional differences, while for Cr, only 13% was accounted. The results suggested that Yibin and Luzhou need to correct the soil acidity if they are set to reduce Hg contamination in tobacco-growing soils. Guangyuan and Panzhihua need efforts to keep the soil pH on track to avoid high contamination levels, and effective measures of soil nutrients supply are required to produce high tobacco leaf quality free from heavy metal content. The findings of this study may be used to ascertain regional differences in heavy metals, particularly Hg and Cr uptake by tobacco plant organs, and to prevent the cultivation areas contamination through soil pH monitoring.
