Abstract Mangrove ecosystems are among the most productive and ecologically significant coastal habitats, providing essential services such as carbon sequestration, shoreline stabilization, and biodiversity support under extreme saline and anoxic conditions. Increasing evidence highlights the pivotal role of endophytic microorganisms residing asymptomatically within mangrove plant tissues in enhancing host adaptation and ecosystem resilience. However, global patterns of their diversity, functional traits, and biotechnological potential remain fragmented across studies. This review provides a comprehensive synthesis of peer-reviewed literature published between 2000 and 2025, retrieved from Web of Science, Scopus, and PubMed, using a structured and reproducible search strategy. A total of 187 studies were analyzed, yielding 152 identified endophytic species. Fungi accounted for approximately 58% of reported taxa, followed by bacteria (39%) and archaea (3%), with Ascomycota and Proteobacteria emerging as dominant phyla across host species and geographic regions. Functionally, mangrove endophytes contribute to nutrient acquisition, stress tolerance, and the production of diverse bioactive compounds with antioxidant, antibacterial, and enzymatic activities. Despite these promising attributes, significant discrepancies between culture dependent and metagenomic approaches influence diversity estimates and functional interpretations, highlighting the need for standardized methodologies and integrative multi-omics frameworks. While endophytes demonstrate clear benefits at the plant level, their large-scale ecological contributions and industrial applicability remain insufficiently validated. This review bridges ecological and biotechnological perspectives by identifying key research gaps, methodological limitations, and priority directions for future studies, ultimately supporting the development of sustainable applications derived from mangrove-associated microbial resources.

Soil salinity remains a major abiotic factor limiting agricultural productivity worldwide, with the situation worsening in parts of Maharashtra, particularly Karad Taluka. This study examined saline soils from various locations within Karad, assessing their physicochemical properties and isolating indigenous halotolerant bacterial strains that exhibit plant growthpromoting rhizobacterial (PGPR) traits. The soil analysis revealed highly alkaline pH levels (8.8-9.4), elevated sodium concentrations, and deficiencies in organic carbon, nitrogen, and micronutrients. Five halotolerant bacterial isolates (Ko1, Va1, Be1, Vm1, and At1) were obtained and evaluated for PGPR activities such as phosphate and potassium solubilization, nitrogen fixation, indole-3-acetic acid (IAA) production, and siderophore synthesis. All isolates demonstrated positive results in phosphate and potassium solubilization, nitrogen fixation, and IAA production, with four also producing siderophores. Notably, isolates Be1, Vm1, and At1 showed strong performance across multiple traits, highlighting their potential as bioinoculant candidates. These findings suggest that native halotolerant PGPR strains from Karad Taluka could enhance soil fertility, improve nutrient uptake, and support plant growth in saline conditions. Future research including field trials and molecular characterization could facilitate the development of environmentally sustainable microbial formulations for saline agriculture.

Understanding the ecological adaptability of Pennisetum giganteum (JUJUNCAO) and its long-term effects on rhizosphere microecology is critical for vegetation restoration in fragile ecosystems. In this study, we investigated the soil physicochemical properties and microbial community structure and function in the rhizosphere of P. giganteum cultivated for 1 and 3 years (Y1, Y3), alongside pre-planting soil (Y0), in a dry-hot valley in Chuxiong, Yunnan, China. Following three years of cultivation, the soil total carbon (TC), organic carbon (SOC), total nitrogen (TN), nitrate nitrogen (NO3−-N), total phosphorus (TP), and available phosphorus (AP) showed significant increases of 84.18%, 96.09%, 61.32%, 212.47%, 24.71%, and 22.19%, respectively, whereas the soil pH remained stable. Fungal communities showed significant declines in diversity and richness and a fundamental structural shift as early as one year after planting. In contrast, prokaryotic communities showed a relatively stable structure. Soil carbon and nitrogen variables were the factors most strongly associated with microbial community composition, and long-term cultivation concurrently enriched the arbuscular mycorrhizal fungi Septoglomus and genera containing potential plant pathogens such as Fusarium and Nectria. The relative abundance of Nectria was positively correlated with the soil carbon and nitrogen contents (p < 0.05), suggesting a potential ecological trade-off between beneficial symbiosis and disease risk. Predicted functional pathway composition indicated a shift in microbial metabolism from basal pathways of phospholipid and nucleotide synthesis toward carbon-nitrogen metabolism via PWY-3781 and the glyoxylate shunt, with fungal community turnover more pronounced. Consequently, P. giganteum demonstrates considerable potential for ecological restoration in dry-hot valleys; however, long-term cultivation deserves attention due to potential nitrate loss and the accumulation of taxa containing potential pathogens, with fungal communities serving as sensitive bioindicators of soil health.
