Abstract As a pivotal environmental factor, light, comprising intensity, photoperiod, and spectrum, governs the entire life cycle of strawberries by mediating alterations in the plant’s morphological, physiological, and biochemical traits. Although extensive research has been conducted on light-mediated growth regulation in horticultural crops, most reviews focus primarily on leafy and fruiting vegetables, with limited attention given to berry crops such as strawberries. Additionally, most existing reviews concentrate on one or several growth stages, failing to systematically characterize light’s effects throughout the entire growth cycle and postharvest stage. This review briefly summarizes the regulatory roles of light More >

Abstract Mexican oregano (Lippia graveolens Kunth) is an aromatic species of high culinary and medicinal relevance. In Mexico, more than 40 taxa with characteristic aroma and flavor are commercially recognized as oregano, with L. graveolens being the most widely distributed and economically important. Despite its relevance, few domesticated or semi-domesticated cultivars exist, and wild populations remain the main source of raw material, raising concerns regarding sustainability and quality standardization. The essential oil and oleoresins of L. graveolens possess recognized bioactivity, including antioxidant, antifungal, antibacterial, and anti-inflammatory properties, largely attributed to phenolic compounds such as thymol and carvacrol. Given the… More >

Abstract The genus Actinidia is primarily functionally dioecious, and early sex identification plays a crucial role in improving breeding efficiency and reducing production costs. In this study, the accuracy of three sex-linked molecular markers (SyGI [Shy Girl], FrBy [Friendly Boy], and SmY1) in sex identification was evaluated in various Actinidia species. The selected marker products were subsequently cloned and sequenced in six wild Actinidia species. Ninety-six wild A. chinensis chinensis accessions and 74 A. chinensis deliciosa accessions, most of which were wild, with only one cultivated, were used for comprehensive primer validation. Thirty-three juvenile A. chinensis chinensis hybrid seedlings were used for practical application… More >

Abstract Tobacco (Nicotiana tabacum, 2n = 48) is a key non-food economic crop, yet its stress response and gene regulatory mechanisms remain poorly understood. By analyzing 603 transcriptome datasets, this study identified 1405 tissue-specific genes, revealing tissue-specific synthesis of terpenoids and other ecologically important secondary metabolites in sepals and other tissues. Comparative stress-response analysis highlighted distinct gene expression patterns in leaves and roots under biotic and abiotic stresses. Additionally, 28,396 expression quantitative trait loci (eQTLs) were mapped in leaves, offering valuable genetic regulatory markers. These findings provide crucial insights into tobacco’s gene expression characteristics and their functional More >

Abstract Catalpa bungei, a fast-growing timber tree, is threatened by the lepidopteran pest Omphisa plagialis. Previous studies in our laboratory successfully generated transgenic C. bungei lines overexpressing Cry genes (Cry1Ab, Cry2A, and Cry9-2) that exhibited resistance to O. plagialis, but their potential impact on soil bacterial communities remains unclear. In this study, we analyzed nine transgenic C. bungei lines (three independent lines for each Cry gene) to characterize their rhizosphere bacterial communities using high-throughput sequencing of the 16S ribosomal DNA (rDNA) V4–V5 regions. A total of 628 amplicon sequence variants (ASVs) were shared among all transgenic and wild-type (WT) lines, forming a stable core… More >

Abstract The study evaluated the skin anti-aging activity of Astragalus sarcocolla leaves extract (ASE) by assessing its antioxidant and inhibitory effect activity on matrix metalloproteinase (MMP), collagenase, elastase, hyaluronidase, and tyrosinase in relation to its chemical composition. Ultra Performance Liquid Chromatography-Mass Spectrometry (UPLC-MS) identified 27 metabolites (15 flavonoids, 8 phenolic acids and their derivatives, and 4 coumarins). ASE showed strong antioxidant capacity in DPPH (IC50 value of 26.05 µg/mL) and FRAP (2433 µM FeSO4/g extract) assays. The extract inhibited MMP-1 and MMP-9 in a concentration-dependent manner and suppressed collagenase, elastase, hyaluronidase, and tyrosinase activities (IC50 = 35.038, 40.748, 61.389,… More >

Abstract Acetogenins are lipidic polyketides with antioxidant, antimicrobial, cytotoxic, and antitumor properties, mainly found in the roots, stems, bark, leaves, and fruits (particularly the seeds) of Annonaceae species. Previous studies have identified acetogenins in the peel and pulp of soursop (Annona muricata L.) fruits. In this research, acetogenins present in starch and pectin extracted from these fruits were analyzed and identified, given their potential importance in the pharmaceutical and possibly in the food industries. The objective was to identify and quantify acetogenins in starch and pectin of soursop fruits. Extraction of both polysaccharides was performed using conventional… More >

Abstract Chilo suppressalis (Walker) is one of the most important rice pests worldwide, posing a significant challenge to effective control. To develop a precision-timed, eco-friendly management strategy, overwintering population investigation and dynamic monitoring of C. suppressalis populations were conducted in the Meishan region of Sichuan, China, from 2023 to 2024. The optimal timing for insecticide application was estimated, followed by field trials evaluating the efficacy of different insecticides. Results demonstrated that the peak emergence of first-generation adults typically occurred in early July (under the environmental conditions of the Meishan region), with the ambient humidity below 75% and temperature… More >

Abstract Keystone taxa are critical for microbial community homeostasis and ecological niche interactions. However, the functions and genomic traits of endophytic keystone fungi in plant tissues remain unclear. Via network analysis, this study identified keystone fungi Plectosphaerella (Plec) and Cladosporium (Clad) in roots/leaves of medicinal Panax plants (P. ginseng, P. quinquefolius, P. notoginseng). Both correlated strongly positively with ginsenoside Rd content in respective tissues (ρ > 0.6, p < 0.001). Co-cultivation confirmed their ability to convert ginsenoside Rb1 to Rd, linked to β-glucosidase activity. Whole-genome sequencing/assembly/evolutionary analysis of the two strains elucidated genomic features for their keystone roles and saponin biotransformation. More >

Abstract Date palm (Phoenix dactylifera L.) seeds, often discarded as by-products during date fruit processing, represent approximately 6–20% of the fruit’s mass depending on cultivar and maturity stage. Although traditionally used for producing activated charcoal and in environmental remediation, their pharmacological potential remains underexplored. This study aimed to evaluate the chemical composition, biological activity, and potential commercial value of seeds from four widely consumed Saharan cultivars (Assiane, Boufegouss, Aziza, and Majhoul) collected in the Figuig region. Soxhlet extraction was employed to obtain seed extracts, which were subsequently characterized by qualitative and quantitative phytochemical screening. The analyses revealed… More >

Abstract Salinity is one of the major abiotic stresses limiting chickpea (Cicer arietinum L.) productivity, particularly in arid and semi-arid regions where soil salinization is intensifying. Developing cost-effective and practical strategies to enhance seedling establishment and early vigor under saline conditions is therefore essential. In this study, we compared two seed-priming agents—1 mM proline and 25 mM NaCl—under identical hydroponic conditions to elucidate tissue-specific responses to 25 mM NaCl stress. Proline priming significantly improved shoot length (by ~23%), total chlorophyll content (by ~19%), and ascorbate peroxidase (ASPOX) activity. In contrast, NaCl priming enhanced root biomass retention (by More >
