Abstract Since pure tobacco stalk (TS) biomass pellet fuels tend to slag, five anti-slagging agents were added to the crushed TS to obtain a pellet fuel that could be used in biomass burners to provide heat for tobacco curing. The obtained results revealed that the main component of TS pellet fuel was K₂Si₂O₅. During fuel combustion process, additives generated higher melting point silicate compounds by Al–K, Ca–K, and Ca–K elemental structures to replace single K elemental structure of TS, enhancing the anti-slagging efficiency of the pellet fuel from 21.63% to 78.29% and promoting the precipitation of K, More >

Abstract The Nicotiana genus, commonly known as tobacco, holds significant importance as a crucial economic crop. Confronted with an abundance of herbivorous insects that pose a substantial threat to yield, tobacco has developed a diverse and sophisticated array of mechanisms, establishing itself as a model of plant ecological defense. This review provides a concise overview of the current understanding of tobacco’s defense strategies against herbivores. Direct defenses, exemplified by its well-known tactic of secreting the alkaloid nicotine, serve as a potent toxin against a broad spectrum of herbivorous pests. Moreover, in response to herbivore attacks, tobacco enhances… More >

Abstract In order to study the combustion characteristics of tar in biomass gasifier inner wall and gasification gas, “tobacco stem semi-tar inside furnace”, “tobacco stem tar inside furnace” and “tobacco stem tar out-of-furnace” were subjected to thermogravimetric experiments, and the combustion characteristics and kinetic characteristics were analyzed. The result shows that “tobacco stem semi-tar inside furnace” has the highest value and “tobacco stem tar out-of-furnace” is has the lowest value on ignition characteristics, combustion characteristics and combustible stability; “tobacco stem semi-tar inside furnace” has the lowest value and “tobacco stem tar outside furnace” has the highest More > Graphic Abstract

Abstract Various strains of powdery mildew (PM), a notorious plant fungal disease, are prevalent and pose a significant threat to plant health. To control PM, transgenic technology can be used to cultivate more resistant plant varieties. In the present study, we utilized the rapid amplification of cDNA ends (RACE) technique to clone the full-length cDNA sequence of the EuCHIT30.7 gene to explore plant genes with disease resistance functions. Bioinformatics analysis revealed that this gene belongs to the GH18 family and is classified as a class III chitinase. The EuCHIT30.7 gene is expressed throughout the Eucommia ulmoides plant, with… More >

Abstract Drought has severely affected the yield and quality of commercial crops. The BRI1 family plays an important role in plant response to drought stress, and BRL3 gene plays an important role in the study of drought in Arabidopsis thaliana. In this study, NtBRL3 was constructed as a vector and genetically transformed to obtain ‘N. Tobacco K326’ overexpression of NtBRL3. The enzyme activities of transgenic tobacco and wild-type tobacco were measured and transcriptome and metabolome analyses were performed. The results showed that the antioxidant enzymes of transgenic tobacco were more active under drought conditions, and 85 significantly differentially metabolites and More >

Abstract Soybean (Glycine max (Linn.) Merr.) annual leguminous crop is cultivated all over the world. The occurrence of diseases has a great impact on the yield and quality of soybean. In this study, based on the RNA-seq of soybean variety M18, a complete CDS (Coding sequence) GmPR1L of the pathogenesis-related protein 1 family was obtained, which has the ability to resist fungal diseases. The overexpression vector and interference expression vector were transferred into tobacco NC89, and the resistance of transgenic tobacco (Nicotiana tabacum L.) to Botrytis cinerea infection was identified. The results show that: Compared with the control, the activities… More >

Abstract Phytocyanin (PC) is a class of plant-specific blue copper proteins involved in electron transport, plant growth, development, and stress resistance. However, PC proteins have not been systematically evaluated in tobacco plants. We determined the whole-genome sequences of the PC family in the tobacco cultivar ‘K326.’ The transcriptome data were used to analyze the expression of the NtPC family at different development stages and tissue-specific genes. Real-time fluorescence quantitative analysis was used to analyze the expression of the NtPC gene family under low temperature and methyl jasmonate stress. The tobacco NtPC family contained 110 members and was divided… More >

Abstract Aluminum is an abundant metal in the earth’s crust that turns out to be toxic in acidic environments. Many plants are affected by the presence of aluminum at the whole plant level, at the organ level, and at the cellular level. Tobacco as a cash crop (Nicotiana tabacum L.) is a widely cultivated plant worldwide and is also a good model organism for research. Although there are many articles on Al-phytotoxicity in the literature, reviews on a single species that are economically and scientifically important are limited. In this article, we not only provide the biology… More >

Abstract Plants are recurrently exposed to myriads of biotic and abiotic stresses leading to several biochemical and physiological variations that cause severe impacts on plant growth and survival. To overcome these challenges, plants activate two primary defense mechanisms, such as structural response (cell wall strengthening and waxy epidermal cuticle development) and metabolic changes, including the synthesis of anti-microbial compounds and proteins, especially the pathogenesis-related (PR) proteins. PR proteins are members of a super large family of defense proteins that exhibit antimicrobial activities. Their over-expression in plants provides tolerance to many abiotic and biotic stresses. PR proteins… More >

Abstract Glyphosate is a non-selective broad-spectrum herbicide that blocks plant growth by inhibiting 5- Enolpyruvylshikimate-3-phosphate synthase (EPSPS), a key enzyme of the shikimate pathway in microorganisms and plants. The full-length epsps cDNA sequence (paepsps, Genebank: KY860582.1) was cloned and characterized for the first time from Phragmites australis. The full-length cDNA of paepsps was 1308 bp encoding a polypeptide of 435 amino acids. The bioinformatic analyses showed that PaEPSPS has highly homologous with EPSPS from other plants. RT-PCR analysis of paepsps expression indicated that the gene expressed in leaves, stems, and roots, with higher expression in leaves. The expression of More >
