“…Organic-rich root exudates that support microbial populations maintain seasonal fluctuations in forest soil. The continuous breakdown of litter also creates an environment that is rich in nutrients, which increases the stability and robustness of microbial genera ( Zheng et al, 2019 ; Wang et al, 2023b ; Solanki et al, 2024 ). The study isolates Ascomycota, Mucoromycota, and Basidiomycota fungi, known for their prevalence in forest ecosystems.…”

In dry deciduous tropical forests, both seasons (winter and summer) offer habitats that are essential ecologically. How these seasonal changes affect soil properties and microbial communities is not yet fully understood. This study aimed to investigate the influence of seasonal fluctuations on soil characteristics and microbial populations. The soil moisture content dramatically increases in the summer. However, the soil pH only gradually shifts from acidic to slightly neutral. During the summer, electrical conductivity (EC) values range from 0.62 to 1.03 ds m-1, in contrast to their decline in the winter. The levels of soil macronutrients and micronutrients increase during the summer, as does the quantity of soil organic carbon (SOC). A two-way ANOVA analysis reveals limited impacts of seasonal fluctuations and specific geographic locations on the amounts of accessible nitrogen (N) and phosphorus (P). Moreover, dehydrogenase, nitrate reductase, and urease activities rise in the summer, while chitinase, protease, and acid phosphatase activities are more pronounced in the winter. The soil microbes were identified in both seasons through 16S rRNA and ITS (Internal Transcribed Spacer) gene sequencing. Results revealed Proteobacteria and Ascomycota as predominant bacterial and fungal phyla. However, Bacillus, Pseudomonas, and Burkholderia are dominant bacterial genera, and Aspergillus, Alternaria, and Trichoderma are dominant fungal genera in the forest soil samples. Dominant bacterial and fungal genera may play a role in essential ecosystem services such as soil health management and nutrient cycling. In both seasons, clear relationships exist between soil properties, including pH, moisture, iron (Fe), zinc (Zn), and microbial diversity. Enzymatic activities and microbial shift relate positively with soil parameters. This study highlights robust soil-microbial interactions that persist mainly in the top layers of tropical dry deciduous forests in the summer and winter seasons. It provides insights into the responses of soil-microbial communities to seasonal changes, advancing our understanding of ecosystem dynamics and biodiversity preservation.

“…A multitude of captivating natural phenomena, including plant disease suppression [ 1 , 2 ], plant growth promotion [ 3 , 4 ], and plant stress resilience [ 5 ], have been discovered to have a microbial basis, prompting extensive investigations into the intricate interactions between microorganisms, hosts, and environmental factors. Soil amendments that gave desirable phenotypes by altering soil microbial communities exemplified that fundamental understanding of the metabolic potential of microbial ecosystems can confer agronomic benefits [ 6 , 7 ]. The development of culture-independent sequencing technologies and the explosion of bioinformatics tools to analyse the resulting meta’omic data have profoundly impacted the understanding of microbial communities in diverse environments.…”

Natural ecosystems harbor a huge reservoir of taxonomically diverse microbes that are important for plant growth and health. The vast diversity of soil microorganisms and their complex interactions make it challenging to pinpoint the main players important for the life support functions microbes can provide to plants, including enhanced tolerance to (a)biotic stress factors. Designing simplified microbial synthetic communities helps reduce this complexity to unravel the molecular and chemical basis and interplay of specific microbiome functions. While synthetic communities have been successfully employed to dissect microbial interactions or reproduce microbiome-associated phenotypes, the assembly and reconstitution of these communities have often been based on generic abundance patterns or taxonomic identities and co-occurrences but have only rarely been informed by functional traits. Here, we review recent studies on designing functional synthetic communities to reveal common principles and discuss multi-dimensional approaches for community design. We propose a strategy for tailoring the design of functional synthetic communities based on integration of high-throughput experimental assays with microbial strains and computational genomic analyses of their functional capabilities.
