As climate change exacerbates drought conditions, global crop production faces an escalating threat. Fortunately, eco-friendly solution lies in harnessing the potential of plant-associated plant growth-promoting bacteria. However, it's crucial to recognize that drought's impact extends beyond plants; it also influences composition, abundance, and activity bacterial communities. Amongst these root-associated communities, Actinobacteria are key players preserving well-being hosts during stress, with research demonstrating minimal disruption communities under conditions. Actinobacteria, found ubiquitously, exceptional candidates for promoting growth due their prevalence soil rhizosphere, adeptness at colonizing roots surfaces, capability produce diverse secondary metabolites stress. With attributes, members phylum present themselves as most promising microbial inoculation plants. They enriched rhizosphere endosphere microbiomes crops enduring water deficit stress Notably, particularly Streptomyces genus, employ various mechanisms, such modulation phytohormone levels, reinforcement antioxidant enzymes, enhanced nutrient uptake, more, alleviate crops. This comprehensive review explores actinobacterial diversity associated plants delves into on Actinobacteria. It examines mechanisms through which mitigate Emphasizing role multi-omics techniques broadening our understanding plant-Actinobacteria interactions, this aims inspire further exploration relatively uncharted territory. Furthermore, discusses future directions application traits, underlining sustainable agricultural practices.

Despite that climate change is currently one of the most pervasive challenges, its effects on plant-associated microbiome still poorly studied. The aim this study was to evaluate impact independent and combinatory effect warming drought assembly oak from seed seedling. In a multifactorial experimental set up, acorns were subjected different temperatures (15 °C, 20 25 °C) soil moisture levels (drought (15%) control (60%)) germination until seedling stage, after which bacterial fungal communities associated rhizosphere phyllosphere characterized by amplicon sequencing qPCR. results showed stronger temperature than diversity more pronounced in phyllosphere. Under condition, had significantly negative diversity. rhizosphere, significant community composition primarily caused species turnover. Regardless temperature, Actinobacteriota enriched drought, group bacteria known increase plant tolerance. This provides new insights into natural ecosystems.

Abstract Actinomycetota have been widely described as valuable sources for the acquisition of secondary metabolites. Most microbial metabolites are produced via metabolic pathways encoded by biosynthetic gene clusters (BGCs). Although many not essential survival bacteria, they play an important role in their adaptation and interactions within communities. This is how bacteria isolated from extreme environments such Antarctica could facilitate discovery new BGCs with biotechnological potential. study aimed to isolate rare strains Antarctic soil sediment samples identify potential based on genome mining exploration clusters. To this end, were sequenced using Illumina Oxford Nanopore Technologies platforms. The assemblies annotated subjected phylogenetic analysis. Finally, present each identified antiSMASH tool, diversity Micrococcaceae family was evaluated. Taxonomic annotation revealed that seven two previously reported NCBI database. Additionally, encoding type III polyketide synthases (T3PKS), beta-lactones, siderophores, non-ribosomal peptide synthetases (NRPS) identified, among others. In addition, sequence similarity network showed a predominant , some genera distinctly grouped. be associated applications antimicrobials, anticancer agents, plant growth promoters, others, positioning them excellent candidates future innovations.

Arid ecosystems constitute a promising source of actinobacteria producing new bioactive molecules. This study aimed to explore different biological activities actinomycetes isolated from the rhizosphere Phoenix dactylifera L. in Ghardaia region, Algeria. A total 18 were and studied for their enzymatic antimicrobial activities. All isolates shared cellulase catalase activity; most them produced amylase (94%), esterase (84%), lecithinase lipoproteins (78%), caseinase gelatinase (72%). The could coagulate (56%) or peptonize (28%) skim milk. Overall, 72% exhibited significant antibacterial activity against at least one test bacteria, while 56% demonstrated antifungal fungi. Based on enzyme production activity, isolate SGI16 was selected secondary metabolite extraction by ethyl acetate. crude extract analyzed using DPPH BSA denaturation inhibition tests, revealing antioxidant power (IC50 = 7.24 ± 0.21 μg mL−1) protein inhibitory capacity 492.41 0.47 mL−1).
