Summary: Phenolic compounds have a positive effect on obesity, diabetes, and cardiovascular diseases. The prevalence of these diseases has increased in the Mexican population, so the phenolic compound intake in the Mexican diet needs to be assessed. A survey conducted on 973 adults found that participants with healthier conditions had a higher intake of phenolic compounds compared to those with more diseases. The study also showed that traditional Mexican food, such as arroz con frijol or enchiladas, positively affected health status.

Summary: High hydrostatic pressure (HHP) can retain anthocyanins and antioxidant activity in jussara juice, but excessive pressure can lead to significant losses. Adding 12.5% sucrose to the juice can enhance consumer acceptance. Although the overall sensory acceptance of HHP-processed juice is slightly higher than that of unprocessed juice, pressurization is not effective in maintaining the anthocyanins and antioxidant activity in jussara juice stored at refrigeration temperature for 60 days.

Summary: Plant-associated microorganisms play important roles in host health by promoting the production of specific metabolites. However, our understanding of these mechanisms in plant-microorganism interaction is still limited. This study aimed to investigate the relationship between olive leaf spot disease incidence and the composition of fungal and secondary metabolites in leaves from olive tree cultivars with different susceptibilities. The results revealed that disease development is linked to leaf fungal and metabolite composition, as well as host genotype. Certain metabolites and fungi were identified as biomarkers of plant tolerance/susceptibility to the disease.

Summary: This study investigated the role of gallic acid (GA) in enhancing salinity tolerance in rice seedlings. Salt stress resulted in osmotic, ionic, and oxidative stress in rice seedlings. Supplemental GA partially reversed salt-induced damages by improving osmotic and ionic homeostasis and enhancing the antioxidant defense system and MG detoxification in rice seedlings.

Summary: The study revealed a dual effect pattern of BPA on the photosynthetic machinery of the seagrass Cymodocea nodosa, with some areas being affected while others remain unaffected. Increasing concentrations of BPA led to a time-dependent increase in H2O2 content in the affected leaf areas, while unaffected areas showed elevated production of phenolic compounds. Ultrastructural observations indicated damage to thylakoids in plastids and effects on Golgi dictyosomes and the endoplasmic reticulum at higher BPA concentrations.

Summary: Reactive oxygen species (ROS), once considered harmful metabolic byproducts, are now seen as integral to cellular programs, activating signaling pathways that regulate plant growth, development, and defense. Adverse environmental conditions can lead to excessive ROS levels, causing oxidative stress and negative impacts on cellular components. Research efforts have focused on enhancing antioxidant mechanisms to improve oxidative stress resilience in both model and crop species.

Summary: Endophytes are microbes that live inside plants without causing harm, and those from desert plants have been shown to improve nutrient uptake, increase plant resilience to abiotic and biotic stresses. Their potential as environmentally friendly alternatives to conventional agricultural solutions, especially in times of increasing drought and opposition to chemicals, make them a promising area for further research and application.

Summary: Entomosporium leaf spot (ELS) is a serious disease that affects hawthorn plants worldwide. Diplocarpon mespili is the most commonly reported pathogen causing this disease. In this study, the pathogen causing ELS on hawthorn in China was identified as a distinct species, D. mespilicola sp. nov, which is similar to D. mespili. The study also determined the optimal temperature and minimum germination time for the pathogen's conidia. This information may be useful in developing disease management strategies for hawthorn production in the future.

Summary: Pyrenophora is a genus of pathogens causing leaf damage and seedborne fungus in Italian ryegrass. Using DNA analysis and morphological characteristics, eight Pyrenophora species were identified, including three newly reported species. Pathogenicity tests showed that all Pyrenophora species could inhibit seed germination and infect Italian ryegrass, with P. dictyoides being the most important seedborne pathogen. The data from this study are useful for accurate identification of Pyrenophora species and the development of seedborne disease management strategies.

Summary: Through microscopy observation, we found that bacteria exist in leaf and bract cells of various plant species and have chemical exchanges with plant cells. The transfer of nitrogen from bacteria to plants is most efficient in plant species with glandular trichomes. We also detected hormones and nitrogenous chemicals around bacteria within plant cells, and some bacteria in glandular trichomes can form nitrate. The significance of nitrogen transfer within leaf and bract cells needs further research, but this symbiotic relationship may play an important role in plant growth, development, and nutrient absorption.

Summary: This study investigated the changes in microbial functional genes, plant nutrients, and soil N2O flux in the rhizosphere soil of ryegrass infected with Epichloe center dot festucae var. lolii. The results showed that the presence of endophytes reduced plant nutrient traits and increased soil nutrient accumulation, as well as altered the microbial environment. The presence of fungal endophytes increased community diversity in certain microbial functional genes and had an impact on N2O fluxes. These changes in plant and soil traits mediated by endophyte infection were closely related to N2O fluxes and the abundance of certain functional genes, such as nifH.

Summary: Phragmites australis is a widely distributed grass species in wetland ecosystems. In North America, the non-native subspecies threatens wetland biodiversity and recreational activities. In other parts of the world, populations are declining due to the Reed Die-Back Syndrome (RDBS). Our study shows that the application of Phragmites can lead to stunted plant growth and changes in soil bacterial communities similar to those affected by RDBS.

Summary: This study used microfluidic chips to investigate foraging strategies and habitat modification of Rhizophagus irregularis symbiotically associated with carrot roots. The researchers found that AMF hyphae can forage over long distances, prefer straight passages, and show branching induction when encountering obstacles. They also observed bi-directional transport of cellular content inside the hyphae and strategic allocation of biomass within the mycelium. Additionally, the AMF hyphae modified the pore-spaces in the chips by clogging them with irregularly shaped spores. These findings have important implications for understanding the impact of AMF on water retention in soils.
