    BIOCELL, Vol.47, No.8, pp. 1783-1791, 2023, DOI:10.32604/biocell.2023.028056

    Abstract Background: ((1-triphenylaminebenzo[c][1,2,5] thiadiazole-4-yl) styryl)-1-methylpyridin methylpyridin-1-ium iodide salt (TBZPy) is a novel photosensitizer that displays excellent photodynamic properties. However, There are few reports on the mechanism of action of the TBZPy photodynamic. Previous studies revealed that photodynamic therapy (PDT) could induce endoplasmic reticulum stress by acting on the endoplasmic reticulum. Therefore, in this study, we investigated the effects of endoplasmic reticulum stress induced by TBZPy-PDT in treating High-risk human papillomavirus (HR-HPV) infection and their underlying mechanisms. Methods: The human cervical cancer cell line HeLa (containing whole genome of HR-HPV18) was treated with TBZPy-PDT. Cell migration, invasion, and colony-forming ability were evaluated… More > Graphic Abstract

    Molecular Mechanism Underlying Plant Response to Cold Stress

    Yiwei Cao, Delight Hwarari, Yasmina Radani, Yuanlin Guan, Liming Yang*

    Phyton-International Journal of Experimental Botany, Vol.92, No.9, pp. 2665-2683, 2023, DOI:10.32604/phyton.2023.024929

    Abstract Low temperature stress is one of the most important factors limiting plant growth and geographical distribution. In order to adapt to low temperature, plants have evolved strategies to acquire cold tolerance, known as, cold acclimation. Current molecular and genomic studies have reported that annual herbaceous and perennial woody plants share similar cold acclimation mechanisms. However, woody perennials also require extra resilience to survive cold winters. Thus, trees have acquired complex dynamic processes to control the development of dormancy and cold resistance, ensuring successful tolerance during the coldest winter season. In this review, we systemically described how woody plants perceive and… More >

    Breaking Barriers: Selenium and Silicon-Mediated Strategies for Mitigating Abiotic Stress in Plants

    Mojtaba Kordrostami1, Ali Akbar Ghasemi-Soloklui1, Mohammad Anwar Hossain2,*, Mohammad Golam Mostofa3,4,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.9, pp. 2713-2736, 2023, DOI:10.32604/phyton.2023.030372

    Abstract Numerous plant species, particularly those that can accumulate selenium (Se) and silicon (Si), benefit from these essential micronutrients. Se and Si accumulation in plants profoundly affects several biochemical reactions in cells. Understanding how plants react to Se/Si enrichment is crucial for ensuring adequate dietary Se/Si intake for humans and animals and increasing plant tolerance to environmental stressors. Several studies have shown that Se/Si-enriched plants are more resistant to salinity, drought, extreme temperatures, UV radiation, and excess metalloids. The interplay between Se/Si in plants is crucial for maintaining growth and development under normal conditions while providing a critical defense mechanism against… More >

    Abstract Somatic embryogenesis receptor-like kinases (SERKs) are receptor-like proteins that contain leucine-rich repeats and are involved in various signaling pathways. This study identified SERK family members in the Paulownia fortunei genome and analyzed their characteristics and expression profiles using bioinformatics methods. We identified 12 SERK genes with relatively conserved gene structures and motifs that were distributed unevenly on eight Paulownia chromosomes. The gene promoters contained various cis-acting elements that regulated the expression of the PfSERK genes in response to hormones and abiotic stresses. Synteny analysis indicated that 10 segmental duplication events had occurred during evolution of the PfSERK family. The expression… More >
