  1. Photosynthetic activity and metabolic profiling of bread wheat cultivars contrasting in drought tolerance

    • Thu, 02/02/2023 - 04:00
    • Frontiers in Plant Science
    • The rapid increase in population growth under changing climatic conditions causes drought stress, threatening world food security. The identification of physiological and biochemical traits acting as yield-limiting factors in diverse germplasm is pre-requisite for genetic improvement under water-deficit conditions. The major aim of the present study was the identification of drought-tolerant wheat cultivars with a novel source of drought tolerance from local wheat germplasm.

    • LWT
    • Staphylococcus aureus, a zoonotic pathogen causes diseases in humans and animals, establishing a robust analytical method is crucial to minimize its adverse impacts. Phage amplification assay (PAA) is a method for indirect detection of target bacteria by detecting the progeny phage. In this study, we proposed a phage amplification assay based on Twortvirinae phage LSA2311 with a broad host range to indirectly detect S. aureus and penicillin-resistant S.

  7. Management of take-all disease caused by Gaeumannomyces graminis var. tritici in wheat through Bacillus subtilis strains

    • Wed, 02/01/2023 - 04:00
    • Frontiers in Microbiology
    • Wheat (Triticum aestivum) is the second largest grain crop worldwide, and one of the three major grain crops produced in China. Take-all disease, caused by Gaeumannomyces graminis var. tritici (Ggt) infection, is a widespread and devastating soil-borne disease that harms wheat production. At present, the prevention and control of wheat take-all depend largely on the application of chemical pesticides.

    • Ecotoxicology and Environmental Safety
    • Marine and intertidal heavy metal pollution has been a major concern in recent years. Tachypleus tridentatus has existed on earth for more than 430 million years. It has suffered a sharp decline in population numbers caused by environmental pollution and anthropogenic disturbance for almost 40 years. However, the effects of heavy metal pollution on juvenile T. tridentatus have not been reported. Here we show the mechanism of cadmium (Cd) detoxification in juvenile T.

  10. Probiotic Properties of Exopolysaccharide-Producing Bacteria from Natto

    • Wed, 02/01/2023 - 04:00
    • International Journal of Food Science
    • Natto is a traditional Japanese food made from soybeans fermented with Bacillus subtilis var. natto. It is also a famous food in Thailand. Potential probiotics were screened from natto. Bacillus subtilis strain VN5 produced the most quantity of exopolysaccharide (EPS), so it was selected to study the properties of microbial EPS and probiotics. The Fourier transform infrared spectrometer or FT-IR spectroscopy confirmed the presence of carboxyl and hydroxyl groups.
