Summary: Endophytic fungi and bacteria were isolated from finger millet, and their effects on the growth parameters and zinc and NPK contents in grains were studied. The best fungal isolates were Aspergillus terreus and Lecanicillium sp., while the best bacterial isolates were Pseudomonas bijieensis and Priestia megaterium. These endophytes showed enhanced growth and increased zinc and NPK concentrations in grains, indicating their potential for biofortification and plant growth promotion in finger millet.

Summary: The potential of plant growth-promoting endophytic fungi (PGPEF) in mycoremediation has gained attention. Two PGPEF isolates from Eupatorium triplinerve leaves were selected based on their ACCD activity and high Cd tolerance. These isolates exhibited IAA and GA production, phosphate solubilization, and siderophore production under Cd stress. Molecular identification confirmed them as species of Colletotrichum. FESEM-EDAX and AAS analyses further demonstrated their Cd bioaccumulation ability in mycelial cells and their impact on rice seedling growth. Successful root colonization was observed, and the detached leaf experiment confirmed their applicability on field-scale as non-pathogenic PGPEF candidates.

Summary: In this study, 70 bacterial isolates were obtained from healthy tea leaves samples from different tea gardens in Chiang Mai, Thailand. These isolates belonged to 11 different genera and showed plant growth-promoting abilities. Two bacterial strains were found to enhance seed germination and seedling growth in sunflower and tomato seeds.

Summary: In natural systems, plant-symbiont-pathogen interactions have important effects on mitigating stresses in plants. Multi-omics technologies can be used to study plant-microbe interactions, particularly plant-endophyte interactions. Endophytes are naturally occurring microbes in plants that do not cause symptoms but provide benefits to their host plants. Understanding the complex mechanisms between plants and endophytes can be achieved through multi-omics approaches.

Summary: The genus Burkholderia has the potential to improve plant performance by enhancing nutrient availability, supporting plant functions, and increasing tolerance to biotic and abiotic stresses. These endophytic bacteria have been extensively studied and shown to colonize plants and provide multiple benefits, including enhanced growth, disease resistance, and stress tolerance. The genomic insights into Burkholderia spp. open up possibilities for various biotechnological applications. Overall, Burkholderia spp. play a critical role in enhancing plant performance and have great potential for agricultural and environmental applications.

Summary: This study found that Trichoderma phayaoense isolated from leaves of Siam weed has the potential to inhibit the growth of Stagonosporopsis cucurbitacearum and Fusarium equiseti, which cause gummy stem blight and wilt disease in muskmelon seedlings. T. phayaoense can also promote plant growth, improve fruit quality, and tolerate commonly used fungicides in field applications, showing promise for disease control in muskmelon production.

Summary: Endophytic microorganisms have the potential to enhance plant growth and resistance to stresses. The strain B9, identified as Bacillus subtilis, showed maximum plant growth promotion in sugarcane. B9 promoted the production of organic acids and phytohormones, and significantly improved the growth and nutrient content of sugarcane seedlings.

Summary: Fungal endophytes establish symbiotic relationships with host plants, promoting mutual growth. Under low nitrogen conditions, Phomopsis liquidambaris promoted rice growth by up-regulating genes related to plant growth promotion and flavonoid biosynthesis. These findings provide new insights into the molecular mechanisms of plant-microbe mutualism.

Summary: This study investigates a possible IAA biosynthesis pathway in Cyanodermella asteris, identifying its ability to synthesize IAA without precursors and through a Trp-independent pathway. The uptake of fungal IAA into Arabidopsis thaliana affects growth phenotypes, with an influx inhibitor altering parameters and partially rescuing the root phenotype in an influx carrier mutation.

Summary: In this study, two co-culturable bacterial endophytes, EP1-AS and EP1-BM, were isolated from the stem internodal segments of Euphorbia prostrata. These novel strains of Enterobacteriaceae, Lelliotia amnigena, showed significant plant growth promotion potential in wheat and tomato through seed-priming treatments. Field trials also demonstrated productive yields in wheat grain and tomato fruit harvests.

Summary: This study aimed to isolate and identify Rhodococcus spp. strains from almond and pistachio rootstocks and trees in Tunisia, using 16S rDNA and vicA gene amplification. Phylogenetic analysis revealed different groups within the strains, with some showing high pathogenicity on pea seedlings. This research sheds light on the presence of undocumented plant-associated Rhodococcus spp. on economically important crops in Tunisia.

Summary: This study is the first report on the presence of endophytes in Cuban rice seeds and their potential to promote seedling growth. The strains Pantoea sp. S5-1, Pseudomonas sp. S5-38, and Pseudomonas sp. S7-1 were selected as the more promising strains for the development of bio-stimulators or bio-inoculants for Cuban rice crops.

Summary: The study found that endophytes play a positive role in promoting growth and stress tolerance of mulberry plants. The use of endophytic Klebsiella aerogenes HGG15 altered the bacterial community structures in the roots and stems of mulberry plants and increased mulberry development and soil potassium content. Metabolite analysis also revealed the presence of abundant lipids and organo-heterocyclic compounds in inoculated mulberry plants, which play important roles in promoting growth and responding to abiotic stress.
