Summary: Fungi have long served as repositories of bioactive secondary metabolites and the demand for new drugs is increasing. Exploring understudied and specialized microbes is a promising way to discover potential new drug lead compounds. Plant-associated fungi known as endophytes, with unique bioactive compounds, have emerged as an important source for drug discovery.

Summary: This study investigated the diversity, antimicrobial, and cytotoxic activities of fungal endophytes obtained from different habitats in Singapore. The majority of the identified strains belonged to the phylum Ascomycota, and the most dominant genus was Colletotrichum. Chemical elicitation and variation of fermentation media led to the discovery of more bioactive strains. Active constituents were isolated and characterized, including a known compound and five novel compounds. These compounds showed strong antifungal and antiproliferative activities.

Summary: This study evaluates the efficacy of ACC deaminase producing methylotrophic bacteria in enhancing cell viability of rice roots under salt stress. The results show that Methylobacterium oryzae strain CBMB20 enhances cell viability by regulating ethylene emission pathway. Additionally, the study reveals that senescence-associated protein (SAP) mRNA expression and enzyme activity are coordinated with major phytohormones. This research provides a mechanistic understanding of the plant-microbe interactions important for stress alleviation, where Methylobacterium spp. plays a central role in enhancing plant biomass through restriction of apoptosis via regulation of ethylene emission.
