Abstract Gilia capitata Sims (Polemoniaceae) is an annual herbaceous plant widely distributed in western North America and cultivated as an ornamental flower. The detailed chemical composition and pharmacological properties of this plant have not been previously reported. This study aimed to investigate the chemical composition and pharmacological activity of aqueous-ethanolic extracts derived from different plant parts (herb, flowers, stems, roots, and fruits). HPLC analysis identified 12 phenolic compounds and 16 amino acids in the aqueous-ethanolic extracts obtained from these plant parts. The biological effects of the extracts were evaluated in vitro, including cytotoxicity, anti-inflammatory response, and wound-healing potential.… More >

Abstract Plants are continuously exposed to abiotic and biotic stresses that threaten their growth, reproduction, and survival. Adaptation to these stresses requires complex regulatory networks that coordinate physiological, molecular, and ecological responses. However, such adaptation often incurs significant costs, including reduced growth, yield penalties, and altered ecological interactions. This review systematically synthesizes recent advances published between 2018 and 2025, following PRISMA criteria, on plant responses to abiotic and biotic stressors, with an emphasis on the trade-offs between adaptation and productivity. It also highlights major discrepancies in the literature and discusses strategies for enhancing plant stress tolerance More >

Abstract Wheat grain morphology, particularly grain length (GL) and width (GW), is a key determinant of yield. To improve the suboptimal grain dimensions of the local anthocyanin-rich variety Guizi 1 (GZ1), we crossed it with Zhongyan 96-3 (ZY96-3), an elite germplasm known for faster grain filling and superior grain size. A genotyping-by-sequencing (GBS) approach was applied to an F₂ population of 110 individuals derived from GZ1 × ZY96-3, resulting in the identification of 23,134 high-quality SNPs. Most of the SNPs associated with GL and GW were clustered on chromosomes 2B, 3A, and 3B. QTL mapping for GL… More >

Abstract Dendrobium officinale (DO) is a well-recognized medicinal and edible plant with a long history of application in traditional medicinal practices across China and Southeast Asia. Recent studies have demonstrated that DO is abundant in diverse bioactive compounds, including polysaccharides (DOP), flavonoids, alkaloids, and bibenzyls thought to exert a range of pharmacological effects, such as anti-tumor and immunomodulatory effects. However, our comprehensive understanding of two key aspects—pharmacological functions and biosynthetic mechanisms—of DO’s major constituents remains limited, especially when considered within the clinical contexts of traditional use. To address this gap, this study reviews DO’s historical applications, clinical effects, and… More > Graphic Abstract

Abstract Cupressus gigantea is an endemic endangered tree species in the Tibet Plateau, and studying the survival status of the different C. gigantea populations and revealing the main environmental factors that affect the population survival are particularly significant for the conservation and sustainable development of endangered species. Based on the 28 sample plots, the Hierarchical Cluster Method was used to classify the C. gigantea populations into four community types. Age structure diagrams were drawn based on the structure of each community, static life tables and survival curves were compiled, and the future development trends of each age group in… More >

Abstract Citrus viroids are small non-coding RNA pathogens that pose a significant threat to global citrus production by reducing fruit yield, quality, and tree longevity. Several viroids, including Citrus exocortis viroid (CEVd), Hop stunt viroid (HSVd), Citrus bent leaf viroid (CBLVd), and newly identified members such as Citrus Viroid VI (CVd-VI) and Citrus Viroid VII (CVd-VII) have been reported from diverse citrus-growing regions. These pathogens are transmitted mainly through vegetative propagation, contaminated tools, and occasionally via seed or pollen, making their management complex. This review synthesizes current knowledge on the biology, structural diversity, transmission, symptomatology, detection,… More >

Abstract To investigate endogenous hormone changes in “Hongyang” kiwifruit from overwintering buds to floral morphogenesis (bell-shaped flowering stage), systematic observations were conducted during the undifferentiated stage, axillary bud differentiation stage, and floral morphogenesis stage from late November 2023 to early April 2024. Paraffin sectioning was employed to examine floral bud morphology, while LC-MS targeted metabolomics quantified changes in 15 endogenous hormones across 8 classes. Results indicated floral bud differentiation commenced from late January to early February and concluded by mid-April, spanning approximately 70 days. Approximately 33 days after axillary bud initiation marked the axillary bud primordium… More >

Abstract The use of organic fertilizers can be an opportunity to increase crop yield and improve soil fertility in semi-arid regions, since soils from these regions usually have unfavourable conditions for plant growth. This research investigates the effects of organic and mineral fertilization on the impact of soil properties (pH, electrical conductivity and organic matter), availability of macro- (N, P and K), micro-nutrients (Fe, Mn, Cu and Zn) and the accumulation of heavy metals (Pb, Cd, Cr) in soil and potato tubers grown under semiarid conditions. A field experiment was conducted in Raqqa Governorate (Syria) using… More >

Abstract Grape (Vitis vinifera L.) cultivation has progressed from early domestication and clonal propagation to modern, data-driven breeding that is reshaping viticulture and wine quality. Yet climatic and biotic constraints still impose heavy losses—downy mildew can reduce yields by ≈75% in humid regions and gray mold by 20–50%—sustaining the need for resistant cultivars. Producer selection, interspecific crossing, and formal improvement programs have generated ~10,000 varieties, although only a few dozen dominate global acreage. Conventional breeding has delivered fungus-resistant “PIWI” cultivars that retain ≥85% of the V. vinifera genome; in Austria, national PIWI varieties are gaining acceptance for combined… More >

Abstract Circadian biorhythms are fundamental in plant adaptability and development. To reveal the effect of organic and inorganic forms of Se, foliar treatments of dandelion with 0.26 mM Se solutions were practiced in two contrasting day times: in the morning with the highest levels of leaf Se and polyphenol (TP) and the lowest dry matter, and in the evening with the opposite characteristics. Compared to the control, the morning Se supply demonstrated a higher increase of root biomass (1.27–1.37 times), Se (1.82–2.85 times), TP content (1.42–1.44 times), and antioxidant activity (AOA) (1.47–1.48 times) than the evening… More > Graphic Abstract
