    Effect of Algae on Melon (Cucumis melo subsp. agrestis var. conomon) Growth and Development under Drought-Stress Conditions

    M. Zeki KARİPÇİN1, Behcet İNAL2,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.11, pp. 3177-3193, 2023, DOI:10.32604/phyton.2023.030979

    Abstract Due to climate change, it is necessary to develop plant varieties that are resilient to climate conditions and resistant to abiotic and biotic stresses. The use of microalgae, which are microorganisms that contain carbohydrates, proteins, lipids, and vitamins, against drought tolerance is a new approach. The aim of the current study was to determine the drought-related mechanisms in the conomon melon genotype and develop drought-tolerant melon cultivars. Morphological, physiological, pomological, and molecular analyses were carried out on the algae-treated genotypes. It has been determined that commercial algae application provides the best results in leaf temperature, leaf relative water contents (LRWC),… More >

    The Function of GABA in Plant Cell Growth, Development and Stress Response

    Yue Jin1, Lulu Zhi1, Xin Tang1, Yilin Chen1, John T. Hancock2, Xiangyang Hu1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.8, pp. 2211-2225, 2023, DOI:10.32604/phyton.2023.026595

    Abstract Gamma-aminobutyric acid (GABA) is a ubiquitous four-carbon non-protein amino acid that is involved in various physiological processes of plant growth and development, such as root architecture, stem elongation, leaf senescence, pollen tube growth, fruit ripening, and seed germination. GABA is also related to plant stress responses, such as drought, salt, cold, and heat stresses. Regulation of GABA in plant stress responses is complex and involves multiple signaling pathways, including calcium and hormone signaling. This paper systematically reviews the synthesis, metabolic pathways and regulatory role of GABA in plants, which will provide new insights into the understanding of plant growth and… More >

    Effect of strawberry vein banding virus and strawberry mottle virus co-infection on the growth and development of strawberry


    BIOCELL, Vol.46, No.1, pp. 263-273, 2022, DOI:10.32604/biocell.2022.016306


    Strawberry mottle virus (SMoV) and strawberry vein banding virus (SVBV) cause diseases on strawberry plants, but the effect of coinfection of SMoV and SVBV on the growth, development, and defense system of strawberry (Fragaria × ananassa Duchesne) remains unknown. We investigated the effect of SMoV and SVBV co-infection on strawberry cultivar ‘Benihope’. The results showed that stem diameter, leaf size, leaf number, relative chlorophyll content, total chlorophyll content, photosynthetic parameters, and stomatal aperture of SMoV and SVBV co-infected strawberry (VIS) plants were in a weaker level than uninfected control plants, indicating that viruses inhibited the growth and photosynthesis of strawberry… More >

    Mycorrhizal Fungal Effects on Growth, Antioxidant Capacity, and Medicine Quality of Paris polyphylla var. yunnanensis

    Nong Zhou1,2, Lingfeng Xu1, Min Yang2, Dongqin Guo1, Qiuxia Gan, Jingjing Zhao1,*

    Phyton-International Journal of Experimental Botany, Vol.90, No.3, pp. 747-759, 2021, DOI:10.32604/phyton.2021.014858

    Abstract A field experiment was conducted to determine the effects of two commercial strains composed of mulple arbuscular mycorrhizal fungi (AMF) species on plant growth, antioxidant capacity, and medicine quality of Paris polyphylla var. yunnanensis in three subtropical soils from Wanzhou, Anshun and Baoshan in fields. The results showed that AMF inoculation enhanced the fungal colonization rate and activities of both succinate dehydrogenase and alkaline phosphatase, thereby, enhancing the mycorrhizal viability of P. polyphylla var. yunnanensis. The concentrations of photosynthetic pigments (chlorophyll a, b, a+b and carotenoids), soluble sugar, soluble protein and photosynthetic capacity were higher in AMF-inoculated plants than in… More >

    Heavy metal accumulation in Pelargonium hortorum: Effects on growth and development

    Orroño DI, RS Lavado*

    Phyton-International Journal of Experimental Botany, Vol.78, pp. 75-82, 2009, DOI:10.32604/phyton.2009.78.075

    Abstract Ornamental plants have been proposed for growing in heavy metal (HM) contaminated soils, and also for phytoremediation. We evaluated (1) biomass production and (2) HM accumulation in Pelargonium hortorum. Plants were grown for 16 weeks on HM (cadmium, chromium, copper, lead, nickel and zinc) enriched soils. Treatments were i) control, non-enriched soil, ii) medium concentration treatment, and iii) high concentration treatment. Four destructive harvests were carried out, and roots, stems, leaves, and flowers were analyzed each time. Concentrations of HM were determined using ICP. Significant reductions in biomass production were observed in HM-enriched soils compared with the control. Different indexes… More >
