[PMID: 38491044 PMCID: PMC10943131 DOI: 10.1038/s41598-024-56430-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 03/06/2024] [Indexed: 03/18/2024] Open
Abstract
Corms of Gladiolus grandiflorus cv. "White Prosperity" was irradiated via red laser at wavelength 635 nm. Various morphological, flowering, elemental and chemical characterizations were studied. Irradiation with different power (5, 20, and 50 mW) and various irradiation time (0.0, 0.5, 1, 3, 5 and 10 min) was studied. Several characters), totaletermined include vegetative growth parameter (spouting days, plant height (cm), leaves number, leaves fresh and dry weights (g/plant), diameter of plant middle part (mm) and leaf area (cm2), floral parameters (flowering days, vase life (day), fresh and dry weights of inflorescence (g/plant), number of flowers per inflorescence, inflorescence length(cm), flowers diameter(cm), number of corms per plant, corms fresh weight(g/plant), circumference/ corms), pigments [total chlorophylls in leaves (SPAD), anthocyanin content (mg/100 g F.W.) in petals], NPK (%) in new corms and chemical composition in corms; total carbohydrates (%),total phenol (μg CE/g (%),total flavonoid (μg CE/g) (%), antioxidant (DPPH IC50 (μg /ml (%), and proline content (μ moles/g). The results showed that the medium level (20 mW) of He-Ne laser at 5 min caused favorable changes in the leaf anatomical structures and other studied characters followed by the low level (5 mW) of He-Ne laser at 5min. 112 bands emerged from 22 SSR primers, ranging between 130 and 540 bp, with 32 bands having polymorphism ranging from 17-100%. Out of the 22 SSR primers, 3 primers exhibited a high polymorphism percentage, i.e., SSR6, SSR16 and SSR22 which exhibited 7 positive markers. These findings revealed the efficiency of SSR primers for differentiating gladiolus plants and revealed that some alleles were affected by laser in their corms and the expression resulted in color or abnormalities in leaves and/or flowers. Mutation in some alleles could result in abnormalities like mutation in the allele with 410 bp revealed by SSR16.

Abstract
Phytochromes (phy) are distributed in various plant organs, and their physiological effects influence plant germination, flowering, fruiting, and senescence, as well as regulate morphogenesis throughout the plant life cycle. Reactive oxygen species (ROS) are a key regulatory factor in plant systemic responses to environmental stimuli, with an attractive regulatory relationship with phytochromes. With the development of high-throughput sequencing technology, omics techniques have become powerful tools, and researchers have used omics techniques to facilitate the big data revolution. For an in-depth analysis of phytochrome-mediated signaling pathways, integrated multi-omics (transcriptomics, proteomics, and metabolomics) approaches may provide the answer from a global perspective. This article comprehensively elaborates on applying multi-omics techniques in studying phytochromes. We describe the current research status and future directions on transcriptome-, proteome-, and metabolome-related network components mediated by phytochromes when cells are subjected to various stimulation. We emphasize the importance of multi-omics technologies in exploring the effects of phytochromes on cells and their molecular mechanisms. Additionally, we provide methods and ideas for future crop improvement.

Bio-Stimulant for Improving Simmondsia chinensis Secondary Metabolite Production, as Well as Antimicrobial Activity and Wound Healing Abilities. PLANTS (BASEL, SWITZERLAND) 2023; 12:3311. [PMID: 37765475 PMCID: PMC10536608 DOI: 10.3390/plants12183311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 09/13/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023]
Abstract
Simmondsia chinensis is a dioecious, long-lived perennial shrub. Its leaves contain several antioxidant flavonoids that have numerous pharmacological effects. Various strategies have been explored to propagate jojoba with enhanced pharmacological values. This research evaluates the bio-stimulatory impacts of He-Ne laser seed irradiation on seed germination, plantlet growth, and alteration of the composition and bioactivities of phytochemicals in jojoba plants. Jojoba seeds were irradiated for 5, 10, and 15 min before in vitro germination. Germination, growth, and multiplication parameters were recorded during germination, multiple-shoot induction, and rooting stages. The wound healing and antimicrobial activities of methanolic extracts from plant lines obtained from the non-irradiated (control) and 10 min irradiated seeds were compared by excision wound model in Wistar male rats and zone of inhibition assay. Our study revealed that laser irradiation increased seed germination, with the highest percentage observed in seeds irradiated for 10 min. Plant lines from the 10 min irradiated seeds produced more explants with higher explant heights and numbers of leaves, more roots, and higher photosynthetic pigment contents than those of control and other laser testings. By comparing plant extracts from the control and 10 min treatments, we observed that extracts from the 10 min treatment exhibited higher percentages of wound contraction and shorter epithelialization periods. In addition, these extracts also resulted in higher levels of angiogenesis elements (VEGF, TGF-β1, and HIF-1α) and reduced the inflammation regulators (IL-1β, IL-6, TNF-α, and NFκB) in the experimental rats. In concordance, extracts from the 10 min treatment also explained raised antibacterial activities towards Staphylococcus aureus and Escherichia coli. Our findings show that pre-sowing seed treatment with a He-Ne laser (632.8 nm) could be a good technique for stimulating S. chinensis plant growth and increasing the impact compound levels and biological activities.

PROTOPLASMA 2023; 260:103-116. [PMID: 35471709 DOI: 10.1007/s00709-022-01762-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/21/2022] [Accepted: 04/14/2022] [Indexed: 06/14/2023]
Abstract
In the current study the role of H2O2 in He-Ne laser-induced effects on seed germination and post-germinative performance of Salvia officinalis seedlings was assessed under both non-stress and saline conditions. Salinity had adverse impacts on seed germination and root length and decreased seed germination tolerance index. Seed priming with H2O2 and He-Ne laser impacted the seed germination and vigoration in a dose-dependent manner. The optimal effects were gathered by energy dose of 6 J/cm2 laser and concentration of 5 mM H2O2. These pre-treatments enhanced seed germination due to increasing contents of total soluble and reducing sugars and the amylase activity in seeds and improved seedling performance under saline and non-saline conditions. Furthermore, Phy B transcripts were upregulated, salt-accrued oxidative stress was mitigated, and the activities of POD and CAT increased in seedlings primed with H2O2 and laser. Interestingly, applying diphenyleneiodonium (DPI as an inhibitor of NADPH oxidase activity) and N, N-dimethyl thiourea (DMTU as a H2O2 scavenger) arrested the upregulation of phy B gene and abolished stimulatory impact of laser priming on the aforementioned attributes under both non-stress and saline conditions. These novel findings suggest that H2O2 as a downstream signal modulates the impacts of He-Ne laser on seed germination, seedling performance and salt acclimation in sage seedlings, and likely phy B also is involved in these responses.

Differential Gene Expression and Withanolides Biosynthesis During in vitro and ex vitro Growth of Withania somnifera (L.) Dunal. FRONTIERS IN PLANT SCIENCE 2022; 13:917770. [PMID: 35774803 PMCID: PMC9237602 DOI: 10.3389/fpls.2022.917770] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Accepted: 05/12/2022] [Indexed: 05/03/2023]
Abstract
Ashwagandha (Withania somnifera L. Dunal) is a medicinally important plant with withanolides as its major bioactive compounds, abundant in the roots and leaves. We examined the influence of plant growth regulators (PGRs) on direct organogenesis, adventitious root development, withanolide biosynthetic pathway gene expression, withanolide contents, and metabolites during vegetative and reproductive growth phases under in vitro and ex vitro conditions. The highest shooting responses were observed with 6-benzylaminopurine (BAP) (2.0 mg L-1) + Kinetin (KIN) (1.5 mg L-1) supplementation. Furthermore, BAP (2.0 mg L-1) + KIN (1.5 mg L-1) + gibberellic acid (GA3) (0.5 mg L-1) exhibited better elongation responses with in vitro flowering. Half-strength MS medium with indole-3-butyric acid (IBA) (1.5 mg L-1) exhibited the highest rooting responses and IBA (1.0 mg L-1) with highest fruits, and overall biomass. Higher contents of withaferin A (WFA) [∼8.2 mg g-1 dry weight (DW)] were detected in the reproductive phase, whereas substantially lower WFA contents (∼1.10 mg g-1 DW) were detected in the vegetative phase. Cycloartenol synthase (CAS) (P = 0.0025), sterol methyltransferase (SMT) (P = 0.0059), and 1-deoxy-D-xylulose-5-phosphate reductase (DXR) (P = 0.0375) genes resulted in a significant fold change in expression during the reproductive phase. The liquid chromatography-mass spectrometry (LC-MS) analysis revealed metabolites that were common (177) and distinct in reproductive (218) and vegetative (167) phases. Adventitious roots cultured using varying concentrations of indole-3-acetic acid (IAA) (0.5 mg L-1) + IBA (1.0 mg L-1) + GA3 (0.2 mg L-1) exhibited the highest biomass, and IAA (0.5 mg L-1) + IBA (1.0 mg L-1) exhibited the highest withanolides content. Overall, our findings demonstrate the peculiarity of withanolide biosynthesis during distinct growth phases, which is relevant for the large-scale production of withanolides.
