    • Tue, 11/29/2022 - 04:00
    • Frontiers in Plant Science
    • Cadmium is one of the most common heavy metal contaminants found in agricultural fields. MutSα, MutSβ, and MutSγ are three different MutS-associated protein heterodimer complexes consisting of MSH2/MSH6, MSH2/MSH3, and MSH2/MSH7, respectively. These complexes have different mismatch recognition properties and abilities to support MMR.

    • Tue, 11/29/2022 - 04:00
    • Frontiers in Microbiology
    • Background

      Ammonia oxidizing bacteria (AOB) in soil are of great biological importance as they regulate the cycling of N in agroecosystems. Plants are known to harbor AOB but how they occupy the plant is an unresolved question.

      Methods

      Metabarcoding studies were carried out using Illumina MiSeq sequencing to test the potential of seed vectored AOB exchange between plants and soil.

    • Toxins
    • Catalase (CAT) can eliminate oxygen radicals, but it is unclear whether exogenous CAT can protect chickens against deoxynivalenol (DON)-induced oxidative stress. This study aimed to investigate the effects of supplemental CAT on antioxidant property and gut microbiota in DON-exposed broilers. A total of 144 one-day-old Lingnan yellow-feathered male broilers were randomly divided into three groups (six replicates/group): control, DON group, and DON + CAT (DONC) group.

    • Comparative Immunology, Microbiology and Infectious Diseases
    • Toxoplasma gondii is an obligate intracellular parasite belonging to the phylum Apicomplexa, which causes the zoonotic disease toxoplasmosis. T. gondii infects almost all warm blood animals. Generally, infected animals are asymptomatic and remain infected for life. Infection of humans occurs by consumption of infected undercooked meat or contaminated vegetables, fruit and water. The aim of this study was to evaluate the prevalence and seroprevalence of T.

    • Food Research International
    • The purpose of this study was to investigate the antibacterial effect and mechanism of cinnamaldehyde on Bacillus cereus spores in ready-to-eat beef. The colour difference and texture of the ready-to-eat beef supplemented with cinnamaldehyde did not differ greatly from the colour and texture of the blank beef. However, cinnamaldehyde has an effective antibacterial effect on the total number of bacterial colonies and B. cereus spores in ready-to-eat beef.
