    Drought-Mediated Modulation in Metabolomic Profiling of Nigella Sativa Leaf, Growth, Ecophysiology and Antioxidants

    Khalid Rehman Hakeem1,2,3,*, Hesham F. Alharby1, M. Irfan Qureshi4

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2023.030212

    Abstract Abiotic stresses, including drought, have been found to affect the growth and medicinal quality of numerous herbs. The proposed study aims to study the effects of different drought regimes on the metabolic profile, growth, ecophysiology, cellular antioxidants, and antioxidant potential of Nigella sativa (Black cumin) leaf. Forty-day-old seedlings of N. sativa were exposed to three regimes of drought (control, moderate and high) for a week. UPLCMS/MS metabolic profile of the leaf reveals the presence of more than a hundred metabolites belonging to anthocyanins, chalcones, dihydro flavonoids, flavonoids, flavanols, flavones, flavonoid carbonoside, isoflavones, etc. Drought was found to More >

    Different Deficit Irrigation Lower Limits and Irrigation Quotas Affect the Yield and Water Use Efficiency of Winter Wheat by Regulating Photosynthetic Characteristics

    Huiqin Li, Mingzhi Zhang*, Na Xiao, Haijian Yang

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2023.031003

    Abstract To determine suitable thresholds for deficit irrigation of winter wheat in the well-irrigated area of the HuangHuai-Hai Plain, we investigated the effects of different deficit irrigation lower limits and quotas on the photosynthetic characteristics and grain yield of winter wheat. Four irrigation lower limits were set for initiating irrigation (i.e., light drought (LD, 50%, 55%, 60% and 50% of field holding capacity (FC) at the seedling-regreening, jointing, heading and filling-ripening stages, respectively), medium drought (MD, 40%, 50%, 55% and 45% of FC at the same stages, respectively), adequate moisture (CK1, 60%, 65%, 70% and 60%… More >

    Functional Studies of Castor (Ricinus communis L.) PLC Family Genes in Arabidopsis Inflorescence Development

    Yanpeng Wen1,#, Rui Luo1,#, Lili Li1, Xiaotian Liang1, Xuemei Hu1, Ruxin Li1, Zhiyan Wang1, Fenglan Huang1,2,3,4,5,*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2023.030960

    Abstract Castor (Ricinus communis L.) is one of the top 10 oil crops in the world, and inflorescence is a trait that directly affects its yield. Phospholipase C (PLCs) is involved in many plant activities and metabolic processes. To study the functions of PLC family genes in the regulation of the inflorescence development of the female line of Lm-type castor aLmAB2, we determined the expression levels of six PLC family genes of three types of inflorescences of aLmAB2 (isofemale line, female line, bisexual line) at different developmental stages. The results showed that the 6 genes of the castor PLCMore >

    Arbuscular Mycorrhizal Fungi Alleviates Salt-Alkali Stress Demage on Syneilesis aconitifolia

    Linlin Fang, Jiamei Xu, Chunxue Yang*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2023.043049

    Abstract Syneilesis aconitifolia is a potential ground cover and decorative material in gardens, which exhibits a strong salt-alkali tolerance, and also has medicinal value. In this study, the arbuscular mycorrhizal (AM) fungi community in the soil surrounding S. aconitifolia roots in the Songnen saline-alkali grassland was used as the inoculation medium for a pot cultivation experiment. After normal culture for 90 days, NaCl and NaHCO3 solutions were applied to subject plants to salt or alkali stress. Solution concentrations of 50, 100, and 200 mmol/L were applied for 10 days, and mycorrhizal colonization, biomass, relative water content (RWC), chlorophyll concentration,… More >

    Transcriptomic Responses of Garlic (Allium sativum L.) to Heat and Drought Stresses

    Seung Hee Eom, Tae Kyung Hyun*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2023.044032

    Abstract Heat and drought are prominent abiotic stressors that limit crop productivity and yield, particularly concerning climate change; therefore, understanding the molecular mechanisms underlying plant stress responses is crucial for stress-tolerant crop production. This study conducted a transcriptomic analysis to elucidate how garlic (Allium sativum L.) responds to drought and heat stress conditions. Transcriptome libraries were generated to identify differentially expressed genes (DEGs) induced by drought and heat stresses. Functional classification and clustering analysis of DEGs revealed stress-specific gene expression patterns. Notably, cell wall-related genes were implicated in the drought response, whereas heat stress was associated with More >

    Polyphenolic Compounds and Antioxidant Activity of Sea Buckthorn (Hippophae rhamnoides L.)

    Ain Raal1,*, Linda Rusalepp2, Tatiana Chiru3, Nicolae Ciobanu3, Kelly Talvistu1, Michelle Shusta1, Oleh Koshovyi1,4, Tõnu Püssa2

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2023.042723

    Abstract The fruits of the Sea buckthorn (Hippophae rhamnoides L.) are a popular plant food and a valuable health product. Cultivating of plants produces a lot of leaves with fine branches as an unnecessary residue, which need valorization. The aim of the study was to estimate (by HPLC-MS/MS) the qualitative and quantitative content of polyphenolic compounds in different parts of H. rhamnoides (HR), and to determine the level of antioxidant activity of leaves and fruits (by DPPH, ABTS methods and ferrozine test). Up to 19 compounds were identified in different parts of HR. The fruits are rich in flavonoids,… More >

    The Cotton GhWRKY91 Gene Negatively Regulates Root Elongation in Overexpressed Transgenic Arabidopsis thaliana

    Yueying Liu#, Yuqing Wang#, Lijiao Gu*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2023.043306

    Abstract WRKY transcription factors play important roles in plant growth, development, and stress responses. Our previous research has shown that the GhWRKY91 gene can delay age-, abscisic acid (ABA)-, and drought-induced leaf senescence when overexpressed in transgenic Arabidopsis plants. To explore in more depth the biological functions of the GhWRKY91 gene, we further observed the root growth of overexpressing transgenic Arabidopsis thaliana under ABA and drought treatment. In this study, we transplanted the germinated seeds of wild-type (WT) and three transgenic lines (OE-12, OE-13 and OE-20) to 1/2 MS solid medium containing ABA and different concentrations of mannitol (simulated… More >

    The Impact of Inoculum Preparation Media on Pollutant Removal through Phycoremediation of Agricultural Drainage Water by Desmodesmus sp.

    Asmaa Salah1, Hoda Sany1, Abo El-Khair B. El-Sayed2, Reham M. El-Bahbohy1, Heba I. Mohamed3,*, Ayman Amin1,*

    Phyton-International Journal of Experimental Botany, Vol., , DOI:10.32604/phyton.2023.031064

    Abstract Water is the most essential natural resource for the future development. Agriculture production is extensively water-dependent and a significant polluter of water resources. So, this work investigated the effect of two different preparation media [Bold’s Basal Medium (BBM) and Domiati cheese whey (DCW)] for agricultural drainage water (ADW) remediation. All treatments were incubated for 6 days. According to the results of biomass productivity, specific growth rate, photosynthetic pigments, and biochemical composition, Desmodesmus sp. can grow in drainage water without dilution. The two treatments significantly reduced the concentration of nitrate, phosphate, chemical oxygen demand, and sodium in More >

    Abstract In recent years, there has been a growing interest in exploring alternative treatments for bone defects. Bone tissue engineering has turned its attention to plant extracts containing osteogenic flavonoids as potential promoters of bone regeneration. In our study, we specifically investigated the extract of Petroselinum crispum, a plant known for its abundance of osteogenic flavonoids such as apigenin, quercetin, and kaempferol. Our objective was to compare the total flavonoid content (TFC) and their accumulation in different sources. We obtained hydrolyzed aqueous extracts from the leaves of parsley plants (grown for 12 weeks in the field), weekly… More >
