    Ibrahim Soe1,2, Emmanuel Odama3, Alex Tamu1,2, Aquilino Lado Legge Wani1,4, Taiichiro Ookawa5, Abdelbagi M. Ismail6, Jun-Ichi Sakagami1,7,*

    Phyton-International Journal of Experimental Botany, Vol.94, No.2, pp. 303-316, 2025, DOI:10.32604/phyton.2025.060016 - 06 March 2025

    Abstract Rice varieties tolerant to submergence regulate shoot elongation during short-term submergence by expressing the SUB1A gene. In contrast, the deep-rooted DRO1 is effectively expressed under drought conditions to enhance water and nutrient uptake. This study investigates the growth and yield of rice with both SUB1A and DRO1 in the background of IR64, under early-season flooding, and mid-season drought. The study used a randomized complete design with two factors: soil moisture treatments (submergence, drought, and their combination) and genotypes. The genotypes included IR64, and three near-isogenic lines (NILs): NIL-SUB1DRO1, NIL-SUB1, and NIL-DRO1. Complete submergence was imposed for 7… More >

    Eman Alhomaidi1, Aisha Umar2,*, Mustansar Mubeen3, Laurent Dufossé4, Yasir Iftikhar3,*, Arpita Das5, Soumya Ghosh6, Muhammad Sibt-e-Abbas7

    Phyton-International Journal of Experimental Botany, Vol.94, No.2, pp. 407-420, 2025, DOI:10.32604/phyton.2025.058035 - 06 March 2025

    Abstract Aspergillus species produce aflatoxins and raise concerns about food safety in departmental stores and manufacturing mills. To address the risks posed by aflatoxins, and to advise the public on the highest quality rice that serves as a nutritious food source, an inquiry following the guidelines outlined in both local and international standards of food safety for the presence of aflatoxins is an essential requirement. Therefore, 16 white rice samples were selected randomly from low/high socio-economic departmental stores from 16 different localities. Grind powdered rice filtrate was extracted using chloroform. The filtrate applied on TLC plates and… More > Graphic Abstract

    Qiang Zhang1,#, Dongsheng Gai1,#, Yong Liu1, Weiyang Liu1, Pengcheng Fu1, Xiwen Shao1, Xuanhe Liang2, Yanqiu Geng1,*, Liying Guo1,*

    Phyton-International Journal of Experimental Botany, Vol.94, No.1, pp. 269-279, 2025, DOI:10.32604/phyton.2025.060551 - 24 January 2025

    Abstract The yield of direct-seeded rice (DSR) was constrained by inadequate grain filling. Recent studies have indicated that paclobutrazol application plays a significant role in enhancing crop agronomic traits and increasing yield. This study aimed to examine the effects of paclobutrazol seed soaking (PSS) on non-structural carbohydrate accumulation and grain enrichment in DSR, potentially providing a theoretical foundation for achieving high-yield DSR cultivation. The experiment utilized two rice varieties, Jiyujing (JYJ) and Jijing305 (JJ305), with seeds soaked in paclobutrazol concentrations of 0 mg L−1 and 100 mg L−1. PSS demonstrated increased chlorophyll content, net photosynthetic rate, and… More >

    Research on Stock Price Prediction Method Based on the GAN-LSTM-Attention Model

    Peng Li, Yanrui Wei, Lili Yin*

    CMC-Computers, Materials & Continua, Vol.82, No.1, pp. 609-625, 2025, DOI:10.32604/cmc.2024.056651 - 03 January 2025

    Abstract Stock price prediction is a typical complex time series prediction problem characterized by dynamics, nonlinearity, and complexity. This paper introduces a generative adversarial network model that incorporates an attention mechanism (GAN-LSTM-Attention) to improve the accuracy of stock price prediction. Firstly, the generator of this model combines the Long and Short-Term Memory Network (LSTM), the Attention Mechanism and, the Fully-Connected Layer, focusing on generating the predicted stock price. The discriminator combines the Convolutional Neural Network (CNN) and the Fully-Connected Layer to discriminate between real stock prices and generated stock prices. Secondly, to evaluate the practical application… More >

    The Role of Phytohormones in Alleviating Salt Stress in Rice

    Lili Guo1, Huiwen Yu2,3,*, Chenxi Zhang1, Mourad Kharbach4

    Phyton-International Journal of Experimental Botany, Vol.93, No.12, pp. 3131-3149, 2024, DOI:10.32604/phyton.2024.058622 - 31 December 2024

    Abstract Rice is a crucial food crop globally. Soil salt stress has adverse effects on the physiology and biochemistry of rice, leading to ionic toxicity and disrupted metabolism. Research aimed at improving salt tolerance and understanding its underlying mechanisms in rice is becoming increasingly important. Phytohormones are crucial in managing rice’s reaction to salt stress by controlling its physiological and biochemical functions. Some phytohormones can improve salt tolerance in rice by affecting gene programming, protein expression, and salt stress signaling, thereby helping rice adapt to salt-stressed environments. This review highlights recent advancements in understanding how various More >

    Yanhong Zhang, Tong Sun, Jinyan Zhu, Qiangqiang Xiong, Jinlong Hu, Haipeng Zhang, Nianbing Zhou, Hongcheng Zhang*

    Phyton-International Journal of Experimental Botany, Vol.93, No.12, pp. 3573-3587, 2024, DOI:10.32604/phyton.2024.057690 - 31 December 2024

    Abstract We investigated the differences in metabolites related to rice yield under different nitrogen fertilizer levels and the regulatory roles of key metabolites in metabolic pathways, in the hope of providing data support from the metabolite level for further regulation of rice yield. This study focused on the rice variety Yangchan 15002 and used non-targeted metabolomics methods to detect the metabolic products of rice leaves under three nitrogen fertilizer levels. The yield of oryza sativa plants under high nitrogen (A3: 315 kg/ha) conditions was significantly higher than that of plants under medium (A2: 270 kg/ha) and… More >

    Mallepu S Likhitha Reddy1, Biplab Mitra1, Ahmed Gaber2, Akbar Hossain3,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.12, pp. 3509-3530, 2024, DOI:10.32604/phyton.2024.056789 - 31 December 2024

    Abstract The rice‒wheat farming system is considered as the greatest energy-intensive agricultural practice in South‒East Asia. In light of declining system production and profitability, burning of residues, soil erosion, depletion of renewable resources, and environmental degradation, the sustainability of the rice‒wheat cropping system is being questioned. As a result, energy and money efficient conservation agricultural methods are becoming more and more necessary to accomplish sustainable output. A field experiment was carried out in this regard to evaluate the effects of varying degrees of rice residue retention and nutrient management options on zero-tillage grown wheat growth, yield,… More >

    Epigenetic regulation of ABCG2 promoter methylation in adolescents with hyperuricemia

    XUETING HUANG1, CHAOJIE XU2, CHEN LI3,*, ZHIXIAN PAN1,*

    BIOCELL, Vol.48, No.12, pp. 1805-1813, 2024, DOI:10.32604/biocell.2024.056431 - 30 December 2024

    Abstract Background: Hyperuricemia is a metabolic disorder which is characterized by increased serum uric acid levels, which can contribute to serious health issues such as gout, cardiovascular disease, and kidney damage. Epigenetic modifications, for example, DNA methylation, exert a crucial function in gene regulation and have been implicated in various metabolic disorders. The ATP-Binding Cassette Subfamily G Member 2 (ABCG2) gene is involved in uric acid excretion, and its expression can be influenced by methylation of its promoter region. Methods: This study involved the design of three guide RNA (gRNA) sequences targeting specific CpG sites within… More >

    Md. Tahjib-Ul-Arif1,2,*, Md Asaduzzaman3, Bir Jahangir Shirazy2,4, Md. Shihab Uddine Khan5, A. M. Sajedur Rahman2,6, Yoshiyuki Murata2, Sozan Abdel Hamed7, Arafat Abdel Hamed Abdel Latef8,9,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.11, pp. 3013-3027, 2024, DOI:10.32604/phyton.2024.058710 - 30 November 2024

    Abstract Chilling is one of the major abiotic stresses for plants, especially for rice cultivation. Many essential metabolic processes for growth and development are temperature-dependent. In that case, reducing the negative effects of cold stress using exogenous chemicals is a possible option. Therefore, the current study examined the effects of pre-sowing seed treatment with different chemicals, viz. hydrogen peroxide (H2O2), salicylic acid (SA), calcium chloride (CaCl2), thiourea (TU), and citric acid (CA) on the germination of rice seeds (cv. BRRI dhan28) under chilling environments. Rice seeds were soaked in distilled water (control), 10 mM CA, 2 mM SA,… More >
