Summary: Cadmium is a toxic heavy metal that has harmful effects on both crops and human health. Crops serve as the main source of cadmium for humans, and it affects human health through the food chain. Crops have evolved detoxification mechanisms to adapt to cadmium toxicity. More research is needed to develop strategies to reduce cadmium accumulation.

Summary: This study aimed to isolate and characterize a new antimicrobial peptide (AMP) from Moringa oleifera seed protein hydrolysates. Through combining cell membrane chromatography and live bacteria adsorption, the active fraction of the AMP was efficiently isolated. The identified peptide MCNDCGA (termed MOp3) showed strong inhibitory effect against Staphylococcus aureus, making it a potential antimicrobial agent in the food industry.

Summary: In this study, 54 strains of endophytic fungi were successfully isolated and identified from various parts of Gannan navel orange. Several strains exhibited significant antibacterial activities against Xanthomonas citri subsp. citri and methicillin-resistant Staphylococcus aureus. Chemical investigation led to the isolation of 24 compounds, including a new botryane sesquiterpene with potent inhibitory activities against multiple bacteria.

Summary: Root systems play a crucial role in plant adaptation to stress conditions, especially drought, and studying their variations and trait selection can enhance cereal crop yield and sustainability. Utilizing cross-species relationships and genomic analysis to explore genetic diversity for genome editing, as well as implementing innovative breeding strategies, are key to developing resilient crop varieties.

Summary: Hermetic storage systems are widely used to minimize stored product losses, and the addition of germinating seeds can enhance their effectiveness in scavenging oxygen. Cowpeas in their fourth to sixth germination stages showed the highest efficiency in scavenging oxygen, while corn took longer to reach the desired level. Hypoxia affected the growth of radicle length and seed reserve mobilization in all crops except for soybeans. Minimal fungal growth was observed on germinating cowpea seeds under hermetic conditions. The fourth stage of germinating cowpeas has potential as an oxygen scavenger due to its shorter growth time and ease of handling. Further research is needed to understand the factors impacting oxygen consumption by germinating seeds.

Summary: Sixteen new polyketides, including four novel carbon skeletons, were isolated from an endophytic fungus. The structures of these polyketides were determined using X-ray diffraction analysis and electric circular dichroism spectra comparison. The polyketides showed low toxicity and exhibited excellent antioxidant activity, with one compound showing greater efficacy than resveratrol in scavenging free radicals. These findings suggest that the novel polyketides could be potential antioxidant agents for neuroprotection.

Summary: This study isolated and identified beneficial endophytic bacteria from Artemisia annua, Moringa oleifera, and Ocimum lamiifolium plants. These bacteria showed potential for promoting plant growth, solubilizing phosphate and zinc, and inhibiting selected test pathogens. Further research is needed to explore the utilization of these bacteria.

Summary: Antibiotic resistance is a global threat to human health, and the discovery of new antibiotics from unexplored habitats is crucial. This study isolated endophytic actinobacteria (EA) from the Citrullus colocynthis plant and investigated their antibacterial properties. Six endophytic actinobacteria were isolated, and they were classified into two families based on morphological features and molecular identification. One of the isolated strains was proposed as a novel species/strain. Five strains showed antagonistic activity against pathogenic bacteria, indicating the potential of Citrullus colocynthis as an untapped source for the discovery of new antibiotics.

Summary: This study isolated a fungus named Aspergillus niveus Fv-er401 from the roots of Foeniculum vulgare (Apiaceae) and investigated its chemical composition and anticholinesterase activity. The results showed that the fungal extract had inhibitory effects on acetylcholinesterase and butyrylcholinesterase. Molecular docking experiments further demonstrated that some of the identified compounds exhibited promising activity as potential inhibitors of these enzymes.

Summary: Genotyping by sequencing revealed the genetic variation within Sarocladium zeae fungi isolated from different Zea germplasm. A novel PCR assay was developed to identify pyrrocidine-producing S.zeae strains. Furthermore, the study of endophytic transmission of S.zeae in maize seedlings improved our understanding of its transmission modes in maize tissues.
