Abstract LONELY GUY (LOG) is a pivotal cytokinin-activating enzyme that plays an important role in plant growth, development, and stress responses. Walnut (Juglans regia), an important woody oilseed species, has not yet undergone systematic identification of its LOG gene family. In this study, we identified 17 JrLOG genes in the walnut genome, which are unevenly distributed across 11 chromosomes. JrLOG gene expansion was primarily driven by gene duplication, along with purifying selection. Members of the JrLOG family were categorized into five groups, each exhibiting analogous gene structures, featured motifs, and conserved domains. Transcriptome and quantitative real-time PCR analyses revealed More >

Abstract The WRKY transcription factors play important roles in various biological processes such as plant development, defense regulation, and stress response. Despite this, there is limited information available on drought-related WRKY genes in maize. Through RNA sequencing (RNA-seq) analysis, a WRKY transcription factor called ZmWRKY25 was identified in this study. ZmWRKY25 belongs to Group II and is localized in the nucleus. Protein interaction analysis revealed that ZmWRKY25 interacts with several proteins involved in the abscisic acid (ABA) signal pathway. Expression of ZmWRKY25 was found to be up-regulated in response to drought, salt, and ABA treatments in tobacco plants. Furthermore, More >

Abstract In order to elucidate the response mechanism of yield and quality of different genotypes of foxtail millet to nitrogen application. In this study, plant physiology and metabolomics were used to study the effects of different amounts of nitrogen (0, 75, 150, 225 and 300 kg hm⁻²) on agronomic characters, yield and quality of Jingu 21 and Zhangza 10. The results showed that with the increase of nitrogen application, the plant height of different genotypes of foxtail millet increased gradually, and the content of stem diameter, yield, protein, fat, lysine, phenylalanine, isoleucine, arginine, aspartic, glutamic, glycine, and… More >

Abstract Relay strip intercropping (RSI) increases soybean nodule number and nitrogen fixation activity at the reproductive stage more than monocropping (M), but the effect of changes in the environment, especially light, on nodules during the coexistence duration and vegetative stage, is unclear. To determine the impact of shading on nodule development at the seedling stage, nodule traits, distribution, and physiological function were compared between M and RSI in a potting experiment in a field environment. Compared with M, nodule number and weight decreased significantly (an average of 81.77% and 93.16%, respectively); thus, the exponential relationship between… More >

Abstract To enhance the productivity of Carya illinoinensis cv. ‘Shaoxing’ and mitigate the loss of flowers and fruits, the effects of different concentrations of Piperonyl Butoxide (PBO) wettable powder (2, 5, and 10 g·L^–1) and Paclobutrazol (PP₃₃₃) (150, 300, and 450 mg·L^–1, based on active ingredients) on 6-year-old ‘Shaoxing’ plants were investigated with water sprayed as the control. The results showed that: (1) Treatment with 10 g·L^–1 PBO and 450 mg·L^–1 PP₃₃₃ significantly inhibited the excessive growth of ‘Shaoxing’ branches. Also, 10 g·L^–1 PBO exhibited the best diameter increment effect on fruiting branches, and 150 mg·L^–1 PP₃₃₃ exhibited the best diameter… More >

Abstract Lignans are a prominent group of phenolic compounds ubiquitously present in the plant kingdom, playing a critical role in both plant physiology and human health. Structurally they are characterized by the dimerization of two phenylpropane units to attain diverse chemical configurations that contribute to their wide range of biological activities. In plants, lignans function primarily as defense molecules, protecting against pathogens, herbivores, and environmental stressors. These compounds also participate in plant growth regulation and lignification processes. From a nutritional and medicinal perspective, lignans are valued for their significant health benefits. They act as phytoestrogens, which… More >

Abstract Quinoa (Chenopodium quinoa Willd.) is regarded as a superfood due to its exceptionally high nutritional value and ability to withstand stress. Six quinoa genotypes (viz., SAU Quinoa-1, Regalona, GPBQ-1, GPBQ-2, GPBQ-3, and GPBQ-4) were characterized for morphological, yield, and nutritional quality attributes while being grown under the agro-climatic conditions of Bangladesh. The field experiment was carried out in the winter season (November 2022–March 2023) at the Agronomy Field Laboratory of the Department of Agronomy, Bangladesh Agricultural University, Mymensingh, using a randomized complete block design with three replications. Data on various qualitative and quantitative traits related to growth… More >

Abstract We investigated the differences in metabolites related to rice yield under different nitrogen fertilizer levels and the regulatory roles of key metabolites in metabolic pathways, in the hope of providing data support from the metabolite level for further regulation of rice yield. This study focused on the rice variety Yangchan 15002 and used non-targeted metabolomics methods to detect the metabolic products of rice leaves under three nitrogen fertilizer levels. The yield of oryza sativa plants under high nitrogen (A3: 315 kg/ha) conditions was significantly higher than that of plants under medium (A2: 270 kg/ha) and… More >

Abstract Entoloma clypeatum, a kind of edible ectomycorrhizal fungus, can be usually symbiotic with Rosaceae fruit trees. Fruit trees have become an important part of China’s agriculture. The present work focused on exploring how E. clypeatum affected symbiotic Rosaceae plants and establishing a symbiotic culture with Malus robusta, Pyrus betulifolia and Prunus armeniaca rootstocks. The results showed that E. clypeatum and three Rosaceae plants can generate cylindrical or clavate mycorrhizae. The inoculation treatment had different degrees of positive effects on the three plants. Relative to the non-inoculated group, biomass in symbiotic plants increased (32.8%–191.1%), and photosynthesis enhanced. In the level of… More >

Abstract Insect pests cause severe crop damage, resulting in substantial economic losses and threats to global food security. Conventional insecticides are low-cost chemical agents that kill the target insects and some non-specific beneficial organisms. Due to their toxic and non-biodegradable nature, these conventional insecticides persist in the environment, thus causing pollution and accumulating in the food chain. The development of novel insecticidal products based on double-stranded (dsRNA)-based RNA interference (RNAi) technology is a sustainable tool to effectively control insect pests. The dsRNA-based insecticides are known for their specificity, non-toxicity, and biodegradability. The current review introduces the… More >
