“…The assays showed that the endophytic species of I. cangae are diversified and promising as potential bacteria to promote plant growth through inoculation. According to Pramanic et al [ 30 ], the endophytic microbiome increases the potential of plant-based systems, providing improvements in the ecological efficiency. The study of endophytes and their inherent functions at specific spatial and ecological locations will also aid in understanding the growth of specific plants in that location and ways of controlling their growth through endophytic microbiome modelling.…”

“…The authors indicated that additional candidate PGPB for duckweeds could be obtained by screening bacterial isolates from diverse aquatic plants. Pramanic et al [ 30 ] detailed the studies on microbiomes and diversity in microbial communities inhabiting the three common free-floating aquatic plants of tropical regions viz., duckweed, water hyacinth, and water lettuce, widely implicated for their bioremediation potential. Studies conducted till date reveal the prevalence and dominance of different Bacillus , Rhodanobacter , Pseudomonas , Rhizobium , Achromobacter , Serratia , Actinobacteria , Proteobacteria , Klebsiella, and Acidobacteria , have also been prominently reported.…”

Isoetes cangae is a native plant found only in a permanent pond in Serra dos Carajás in the Amazon region. Plant-associated microbial communities are recognized to be responsible for biological processes essential for the health, growth, and even adaptation of plants to environmental stresses. In this sense, the aims of this work were to isolate, identify, and evaluate the properties of endophytic bacteria isolated from I. cangae. The bioprospecting of potentially growth-promoting endophytes required the following steps to be taken: isolation of endophytic colonies, molecular identification by 16S rDNA sequence analysis, and evaluation of the bacterial potential for nitrogen fixation, production of indole acetic acid and siderophores, as well as phosphate solubilization and mineralization. Bacillus sp., Rhizobium sp., Priestia sp., Acinetobacter sp., Rossellomorea sp., Herbaspirillum sp., Heyndrickxia sp., and Metabacillus sp., among other bacterial species, were identified. The isolates showed to be highly promising, evidencing the physiological importance for the plant and having the potential to promote plant growth.

“…The term 'endophytic fungi' may be defined as "those fungi that colonize and live within the intercellular spaces of living plant tissue by forming symbiotic relationships without any harmful effect on the host plant" [1]. These endophytic fungi may inhabit the host plants for all or part of their life cycle, depending on the availability of the host tissue.…”

Endophytic fungi associated with medicinal plants produce compounds that have vast biological activities. Anaphalis contorta is a highly therapeutic plant that has been used in traditional medicine by various communities. In the present study, the endophytic fungus Plectosphaerella oligotrophica S8A26 was isolated from the stem part of A. contorta and assessed for its plant growth promotion abilities, and showed positive results for phosphate solubilization and ammonia production. The secondary metabolites were analyzed for the presence of seven biochemicals, which indicate the presence of flavonoids, phenols, saponins, and steroids. The total flavonoid content and total phenolic content were recorded to be 25.67 µg of QE/mg of EE and 5.06 µg of GAE/mg of EE, respectively. The isolate was allowed to synthesize silver nanoparticles and characterized using X-ray diffraction, Energy Dispersive X-ray, Particle size distribution, and Zeta potential. XRD analysis has shown the AgNPs are crystalline with an average size of 24.81 nm. EDX study reveals silver as the main component with 48.63%. Particle size distribution indicates that the majority of the particles occur in the size range of 65–70 nm. Zeta potential value of −31.8 mV shows that the AgNPs are stable. Studies like the biological activities of the endophyte as well as AgNPs, secondary metabolite profiling, and the isolation of bioactive compounds would constitute important future research.

“…Aquatic plant is a favourable ecological niche for microbial diversification and propagation, especially the roots that serve as hot spots for microbial diversity. These plants-associated microbes play a vital role in primary nutrient cycling, eliminating various pollutants, denitrification and phosphate uptake, influencing dissolved oxygen and generally have a mutualistic association with the host plants (Ávila et al, 2019; Achá et al, 2005, Pramanic et al, 2023). It is imperative to understand the WH-associated microbial population that significantly influences the overall nutrient cycling and biochemical process.…”

Water hyacinth (WH) is a widespread floating invasive aquatic plant having a prolific reproductive and dispersion rate. With the aid of its root-associated microbes, WH significantly modulates the ecosystem's functioning. Despite their irrevocable importance, the WH microbiome remains unexplored in detail. Here, we present a shotgun analysis of WH rhizobiome (from urban rivers and a lake) and their surrounding water to unveil the diversity drivers and functional relationship. PCoA analysis revealed that microbial diversity of the WH is significantly shaped by the type of the aquatic bodies (River Vs Lake) (ANOSIM-R of 0.94 to 0.98 and R2 of 0.36 to 0.54). Temporal variations (River WH_2020 vs WH_2022) (R of 0.8 to 1 and R2 of 0.17 to 0.41) were observed in river WH, which could be mainly attributed to the transient taxa as there was higher sharing of core bacteria (48%). Also, the WH microbiome significantly differed (R= 0.46 to 1.0 and R2 of 0.18 to 0.52) from its surrounding water. WH inhabited more unique core members (42 to 45%), suggesting vertical transfer and selectivity in the microbiome. Functional metagenomics depicted the WH microbiome to harbour 140 pollutant-degrading enzymes involved in the degradation of various xenobiotic pollutants such as hydrocarbons, plastics, and dye. Moreover, an observed higher prevalence of metal and biocide resistance genes highlighted the persistence of resistant microbes assisting WH in environmental remediation application.
