Abstract β-Aminobutyric acid (BABA) is a physiologically active plant compound that has not been extensively studied. It has been shown to increase resistance to biotic and abiotic stress factors and enhance seed germination in certain plant species. However, its effects on cereal grains with low germination rates have not yet been studied. This study investigated the effects of BABA on the germination of aged triticale seeds, the metabolite content of seedlings, and the state of their antioxidant systems. The study found that a three-hour treatment of seeds in BABA solutions at concentrations ranging from 0.1 to… More > Graphic Abstract

Abstract Magnolia officinalis is a perennial deciduous tree that has medicinal properties. The AP2/ERF gene family has a number of roles in long-term growth and metabolism. The expression of this function varies with the growth period. In this work, based on the transcriptome data of Magnolia officinalis, the complete coding gene of Magnolia officinalis was obtained, and the corresponding protein sequence was retrieved from NCBI and compared with the model plant Arabidopsis thaliana. After screening, 75 protein sequences from the AP2/ERF gene family were identified and called MoAP2/ERF1–MoAP2/ERF75, followed by bioinformatics analysis. 75 AP2/ERF gene families were found and classified into four… More >

Abstract Exploring the phenotypic trait variation and diversity of kiwifruit male plant resources can support selection, breeding, and genetic improvement, ultimately enhancing agricultural production. In this study, 50 kiwifruit male plants were collected from the resource nursery of Sichuan Provincial Natural Resources Bureau. The phenotypic variation of the germplasm was analyzed using 16 quantitative traits. The analysis involved coefficient of variation (CV), Shannon-Wiener index (H), principal component analysis, correlation analysis, cluster analysis, and comprehensive evaluation. The results showed that the variation range of 16 phenotypic traits in kiwifruit male germplasm resources was 1.55% to 83.71%, with… More >

Abstract Acer paxii belongs to the evergreen species of Acer, but it exhibits a unique feature of reddish leaves in fall in subtropical regions. Although the association of AP2/ERF transcription factors with color change has been well-documented in prior research, molecular investigations focusing on AP2/ERF remain notably lacking in Acer paxii. This research focuses on performing an extensive genome-wide investigation to identify and characterize the AP2/ERF gene family in Acer paxii. As a result, 123 ApAP2/ERFs were obtained. Phylogenetic analyses categorized the ApAP2/ERF family members into 15 subfamilies. The evolutionary traits of the ApAP2/ERFs were investigated by analyzing their… More >

Abstract Wheat stripe rust, a devastating disease caused by the fungal pathogen Puccinia striiformis f. sp. tritici (Pst), poses a significant threat to global wheat production. Growing resistant cultivars is a crucial strategy for wheat stripe rust management. However, the underlying molecular mechanisms of wheat resistance to Pst remain incompletely understood. To unravel these mechanisms, we employed high-throughput RNA sequencing (RNA-Seq) to analyze the transcriptome of the resistant wheat cultivar Mianmai 46 (MM46) at different time points (24, 48, and 96 h) post-inoculation with the Pst race CYR33. The analysis revealed that Pst infection significantly altered… More >

Abstract The production of crops is badly affected by climate change globally. Mitigation of adverse effects of climate change is in need of time through different management practices such as developing tolerant genetic resources, hormonal applications to boost defense systems, nanoparticles, and balanced fertilization. The nano-hormonal synergy had the potential to mitigate the adverse effects of climate change by modulation of morpho-physiological and biochemical activities. Plant growth, yield, and quality can be enhanced with the supplementation of nano-hormonal interactions. Therefore, the current study explores the synergy between nanoparticles and phytohormonal use. The nanoparticles, even in low… More >

Abstract Grapevine is unique among crops because its domestication resulted not only in new morphological characteristics, but also in altered reproductive mechanisms. Viticulture involves a change from a dioecious to a hermaphroditic mating system, which makes the reproductive system more efficient. In consequence and the fact that it is one of the oldest and most economically important cultivated plants, Vitis vinifera could be defined as an over-domesticated species. Here we review some key aspects in viticulture. The main areas of interest have remained consistent throughout history, including the origin and characterisation of cultivars, resistance to environmental conditions,… More >

Abstract Species of the genus Paenibacillus, especially those from extreme environments that have been reported, are known for producing bioactive compounds with agricultural and biotechnological applications. In this study, we investigated the genomic and biochemical potential of Paenibacillus sp. VCA1 strain isolated from a thermophilic environment. Taxonomic identification was performed using whole genome similarity analysis, TETRA four-nucleotide frequency of occurrence analysis, ANI average nucleotide identity analysis, and gene distance analysis using digital DNA-DNA hybridization (dDDH). Functional analysis of the strain VCA1 was performed by detecting genes, enzymes, and genome subsystems involved in biocontrol and plant growth promotion,… More >

Abstract Chlorophyll fluorescence, particularly the parameter F_v/F_m, has emerged as a reliable, non-invasive indicator of the maximum quantum efficiency of Photosystem II (PSII) in plants. Over the past decade, significant research has leveraged F_v/F_m to evaluate plant responses to a wide range of biotic and abiotic stresses, as well as to support crop improvement and ecological monitoring. This review synthesizes recent progress in understanding the physiological basis, measurement techniques, and applied significance of F_v/F_m across diverse plant systems. We highlight methodological advancements in fluorescence imaging and remote sensing, identify consistent patterns and contrasting findings in stress-response studies, and More >
