Abstract As one of the most toxic heavy metals in environment, cadmium (Cd) poses a severe threat to plant growth. We previously reported that overexpression Tamarix hispida V-ATPase c subunit ( ThVHAc1 ) improved Cd tolerance Saccharomyces cerevisiae . In current study, we further explored conferred by Arabidopsis and T. transgenic had higher seed germination, biomass chlorophyll content under CdCl 2 treatment. Cd-stressed plants, significantly activity affected expression other...

Vacuolar H+-ATPase (V-ATPase) is a vital protein complex involved in abiotic stress response plants. The G subunit of Juglans regia (JrVHAG1) was previously identified as drought tolerance-related gene the ABA (abscisic acid)-signal pathway. Heavy metal becoming major detriment for plant growth, development, and production. In order to understand role JrVHAG1, potential function mechanism JrVHAG1 exposed CdCl2 confirmed this study. Transcription induced by increased 58.89-fold (roots)...

Lack of complete genomic information concerning Vicia sepium (Fabaceae: Fabeae) precludes investigations evolution and populational diversity this perennial high-protein forage plant suitable for cultivation in extreme conditions. Here we present the annotated chloroplast genome important wild resource plant. V. includes 76 protein-coding genes, 29 tRNA four rRNA genes one pseudogene. Its 124,095 bp sequence has a loss inverted repeat (IR). The GC content whole genome, protein-coding,...

GRAS transcription factor (TF) family is unique and numerous in higher plants with diverse functions that involving plant growth development processes, such as gibberellin (GA) signal transduction, root development, nodule formation, mycorrhiza formation. Walnut tree exposed to various environmental stimulus causing concern about its resistance mechanism. In order understand the molecular mechanism of walnut adversity response, a TF (JrGRAS2) was cloned characterized from Juglans regia this...

Broussonetia papyrifera is a widely distributed economic tree species, and it also pioneer species in adverse environments. In order to investigate the growth adaptation mechanism of B. under cadmium (Cd) contaminated soil, potted experiments were used with six-month treatments study Cd enrichment transportation, morphological physiological characteristics tissues. The results showed that mainly accumulated root when concentration was high (14.71 mg/kg), biomass significantly reduced by...

Walnut (Juglans regia) is known as a promising woody oil crop with abundant polyunsaturated fatty acids in its kernel. However, the regulation mechanism of walnut accumulation and acid metabolism still poorly understood, which restricted breeding genetic improvement high-quality oil-bearing walnuts. To reveal molecular accumulation, considering potential microRNA (miRNA) seed development, this study, content kernel on 80th, 100th 120th day after flowering (DAF) was tested corresponding...

Walnuts (Juglans regia L.) are known for their nutrient-rich nuts and one of the important economic tree species in world. However, due to global warming soil salinization, walnuts suffer from various abiotic stresses. TIFY (TIF[F/Y]XG) proteins play an essential role growth development plants, signal transduction, stress response plants. At present, although gene family a number plants has been identified studied, how takes part tolerance remains obscure many functions require further...

Walnut is a significant woody oil tree species that has been increasingly affected by anthracnose in recent years. Effective control crucial for walnut yield and quality, which requires comprehensive understanding of the response mechanisms to Colletotrichum gloeosporioides. The PR10/Bet v1-like proteins are involved defense against various disease, therefore, this study, 7 JrBet v1s were identified from transcriptome (named v1-1~1-7), whose open reading frame (ORF) was 414~483 bp length...

Abstract Juglans regia , an important economic tree species, is planted all over the world, and drought one of crucial factors limiting its growth development. The various polyphenol content in walnut plants constitutes material bases for differences stress resistance among germplasms. However, molecular mechanism underlying response mediated by -dependent pathways remains unclear. v-Myb avian myeloblastosis viral oncogene homolog (MYB) protein transcription play regulatory roles process...

Nitrate is a primary source of nitrogen pollution in aquatic environments, making timely monitoring its levels surface and drinking water essential for environmental protection public health. Conventional laboratory methods are time-consuming require specialized expertise, while chemical electrode-based online detection systems hindered by challenges-such as frequent calibration ion cross-interference-which limits their suitability long-term monitoring. To address these limitations, novel...

Broussonetia papyrifera is a deciduous tree with significant economic and medicinal value. It demonstrates notable physiological adaptability to mining areas severe manganese contamination pioneering species in the field of ecological restoration. Flavonoids are vital secondary metabolites that improve plant resilience environmental stresses. In study presented herein, immature mature fruits B. grown normal high environments were used as test materials. fruit was subjected transcriptome...

Eukaryotic translation initiation factor 1A (eIF1A) functions as an mRNA scanner and AUG codon locator. However, few studies have clarified the role of eIF1A in abiotic stress. In this study, we cloned (TheIF1A) from Tamarix hispida found its expression to be induced by NaCl polyethylene glycol (PEG) roots, stems leaves. Compared a control, TheIF1A root was increased 187.63-fold when exposed for 6 h, suggesting potential stress response gene. Furthermore, transgenic tobacco plants...

Soil heavy metal pollution is a common problem in mining areas. The soil of the Xikuangshan located Lengshuijiang, Hunan Province, China contains various excessive metals, especially antimony and cadmium. Previous studies have shown that metal-tolerant microorganisms screened from areas potential to adsorb metals. In this study, we out cadmium tolerant fungus named XK8 slags collected Xikuangshan. Then, explored single binary biosorption characteristics Cd(II) Sb(III) on it. our results, was...

Camellia oleifera is one of the four largest woody edible oil plants in world with high ecological and medicinal values. Due to frequent interspecific hybridization, it was difficult study its genetics evolutionary history. This used C. that collected on Hainan Island conduct our research. The unique island environment makes quality tea higher than other species grown mainland. Moreover, a long-term geographic isolation might affect gene structure. In order better understand molecular...

Abstract Background Walnut ( Juglans regia ) is an important tree cultivated worldwide and exposed to a series of both abiotic biotic stress during their life-cycles. The heat transcription factors (HSFs) play crucial role in plant response various stresses by regulating the expression stress-responsive genes. HSF genes are classified into 3 classes: HSFA , HSFB HSFC . gene has transcriptional activation function main regulator high temperature-induced expression. negatively regulates...
