    Analysis of Intraspecies Diversity of Rice Reveals Variation Patterns of Oryza sativa Basic Leucine Zippers

    Jing Wang1,#, Wenqing Xiao1,#, Qingnan Wang1, Xu Wang1, Bin Jiang1, Yangchun Han2, Yang Sun1,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.5, pp. 859-873, 2024, DOI:10.32604/phyton.2024.048151

    Abstract The basic leucine zipper (bZIP) is an important class of transcription factors in plants, playing a critical role in plant growth and development and responses to biotic and abiotic stress. Due to gene presence/absence variations, it is limited to identify bZIP genes based on the reference genome. Therefore, we performed the bZIP gene family analysis in the rice pan-genome. By employing a rice pan-genome, ninety-four OsbZIPs (72 core genes and 22 variable genes) were identified and divided into 11 groups in a phylogenetic tree. Based upon Ka/Ks values in 33 accessions, OsbZIPs were subjected to different selection… More >

    Development of Spectral Features for Monitoring Rice Bacterial Leaf Blight Disease Using Broad-Band Remote Sensing Systems

    Jingcheng Zhang1, Xingjian Zhou1, Dong Shen1, Qimeng Yu1, Lin Yuan2,*, Yingying Dong3

    Phyton-International Journal of Experimental Botany, Vol.93, No.4, pp. 745-762, 2024, DOI:10.32604/phyton.2024.049734

    Abstract As an important rice disease, rice bacterial leaf blight (RBLB, caused by the bacterium Xanthomonas oryzae pv. oryzae), has become widespread in east China in recent years. Significant losses in rice yield occurred as a result of the disease’s epidemic, making it imperative to monitor RBLB at a large scale. With the development of remote sensing technology, the broad-band sensors equipped with red-edge channels over multiple spatial resolutions offer numerous available data for large-scale monitoring of rice diseases. However, RBLB is characterized by rapid dispersal under suitable conditions, making it difficult to track the disease at… More >

    Phyton-International Journal of Experimental Botany, Vol.93, No.4, pp. 789-806, 2024, DOI:10.32604/phyton.2024.049088

    Abstract This study aimed to examine the effects of inoculating Fritillaria taipaiensis P.Y.Li leaves with different strains of potassium-solubilizing bacteria (KSB), or combinations thereof, focusing on aspects of photosynthesis and physiological and biochemical characteristics. At present, some studies have only studied the rhizosphere microbial community characteristics of F. taipaiensis and have not discussed the effects of different microbial species on the growth promotion of F. taipaiensis. This paper will start from the perspective of potassium-solubilizing bacteria to conduct an in-depth study. Seed cultivation commenced at the base with three different KSBs in early October 2022. The growth of F. taipaiensisMore >

    GENG SU, YA-JIE JIANG, HONG-BIN JU, YA-KUI WANG, TAO GENG*

    Journal of Polymer Materials, Vol.36, No.4, pp. 293-304, 2019, DOI:10.32381/JPM.2019.36.04.1

    Abstract Two kinds of poly quaternary ammonium salts (PQAS) namely PDMC (poly (methacryloxyethyl trimethyl ammonium chloride)), CPAM (methacryloxyethyl trimethyl ammonium chloride / acrylamide copolymer) were prepared. The chemical structures of the PQAS were characterized by Fourier transform infrared (FT-IR), nuclear magnetic resonance (1 H NMR) spectrum, thermogravimetric analysis (TGA), and scanning electron microscope (SEM). The antibacterial activity of PQAS against three kinds of bacteria and one kind of fungus, was evaluated by the method described in QB/T 2738-2012. Antibacterial tests showed that the antibacterial activity increased with the increase of cationicity and molecular weight on PQAS. It More >

    Preparation of Chitin-Glucan Microsphere via SprayDrying Technique and their Antibacterial Activity

    ANU SINGH AND P.K. DUTTA*

    Journal of Polymer Materials, Vol.38, No.1-2, pp. 63-69, 2021, DOI:10.32381/JPM.2021.38.1-2.6

    Abstract The experiment was designed to examine the microsphere of the chitin-glucan complex. We formed a chitin-glucan microsphere (ChGMS) from the spray dryer technique. SEM images observed that shape of ChGMS was spherical. From particle size analyzer and SEM analysis both showed that the size of particles was in the range of 1.5 to 3.5 µm. It showed amorphous nature after the formation of microsphere particles of chitin-glucan. The effect of chitin-glucan complex and ciprofloxacin loaded chitin-glucan microsphere on Bacillus subtilis and Escherichia coli were also tested. Antibacterial analysis was indicating that the ciprofloxacin loaded chitinglucan More >

    Gamma Radiation Induced Mutual Grafting of Quaternary Ammonium-Based Monomer on to Rayon Fibers to Improve its Water Absorbency and Antibacterial Efficacy

    SUBRATA PAL1,2, BHUVNESHWAR RAI1, AJAY KUMAR TYAGI1, SUNITA RATTAN2, VIRENDRA KUMAR3

    Journal of Polymer Materials, Vol.39, No.1-2, pp. 55-70, 2022, DOI:10.32381/JPM.2022.39.1-2.4

    Abstract The present work is focused on the study of antimicrobial and water absorption properties of the surface of grafted rayon fiber with quaternary ammonium-based salts containing 3- Acrylamidopropyl trimethyl ammonium chloride (APTAC) monomer induced by gamma radiation. Grafting was qualitatively confirmed by FTIR-ATR,TGA, SEM and by calculating grafting yield and grafting efficiency. The performance was examined for water absorbency and antibacterial efficacy (R) against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus). Study showed that water absorption, grafting yield and grafting efficiency increased steadily with the increase in monomer concentration and absorbed gamma irradiation More >

    Journal of Renewable Materials, Vol.12, No.2, pp. 285-304, 2024, DOI:10.32604/jrm.2023.043919

    Abstract With the increase in antimicrobial resistance, it has become necessary to explore alternative approaches for combating and preventing diseases. DB-cinnamaldehyde (CNM) and Benzyl4-amino (B4AM) are bioactive compounds derived from chalcones but with restricted solubility in aqueous media. Nanoemulsions can enhance the solubility of compounds and can be a promising alternative in the development of novel antimicrobials, with reduced side effects and prolonged release. The objective of this study was to evaluate the stability of oil-in-water nanoemulsions loaded with two distinct types of chalcones at two different dosages, to propose a stable formulation with antimicrobial properties.… More > Graphic Abstract

    Ahmed Hassan Abdou1,*, Omar Abdullah Alkhateeb2, Hossam Eldin Hamed Mansour3, Hesham S. Ghazzawy4, Muayad Saud Albadrani5, Nadi Awad Al-harbi6, Wasimah B. Al-Shammari7, Khaled Abdelaal8,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.12, pp. 3305-3321, 2023, DOI:10.32604/phyton.2023.044780

    Abstract Plant growth-promoting bacteria (PGPB) play an important role in improving agricultural production under several abiotic stress factors. PGPB can be used to increase crop growth and development through hormonal balance and increase nutrient uptake. The positive effect of PGPB may be due to its pivotal role in morphophysiological and biochemical characteristics like leaf number, leaf area, and stem length. Furthermore, relative water content, chlorophyll content, carotenoids, antioxidant enzymes, and plant hormones were improved with PGPB treatment. Crop yield and yield components were also increased with PGPB treatment in numerous crops. The anatomical structure of plant… More >

    MENGYING MAO1,2,3,#, TING DONG1,2,3,#, YANJING LIANG3,4, KEYONG YUAN1,2,3, QIAOQIAO JIN1,2,3, PENGFEI ZHANG1,2,3, ZHENGWEI HUANG1,2,3,*

    BIOCELL, Vol.47, No.10, pp. 2187-2193, 2023, DOI:10.32604/biocell.2023.042357

    Abstract The oral microbiota is a vital part of the human microbiota that functions in various physiological processes and is highly relevant to cancers and other diseases. With the alterations of host immune competence, the homeostatic balance existing between the oral microbiota and host may be disturbed and result in the development of diseases. Numerous observations have suggested that small RNAs are key regulators of bacterial pathogenesis and bacteria-host interactions. Further, bacterial small RNAs are considered to be promising biomarkers for the development of novel, and efficacious therapies for oral dysbiosis. Mechanistic insights into how oral More > Graphic Abstract
