“…The Gleysol analysed by Wolińska et al [51] was more acidic (pH~5.9) than that analysed here. Literature reports indicate that soil microbiomes may be dependent on both soil type and pH [6,[56][57][58]. All organisms of the Thaumarcheota identified are chemolithoautotrophic ammonia-oxidisers, may play important roles in biogeochemical cycles, and are among the most abundant archaea on Earth [59,60].…”

The quality of a soil environment affects the microbial community that inhabits it. We decided to examine whether soils formed from river sediments, located in an area of high biodiversity of organisms, are fertile and microbiologically diverse. Fluvisols are considered to be one of the most fertile soils. In this research, bacterial and metabolic diversity, as well as physico–chemical parameters, in three Fluvisols from the Vistula River Gorge of Lesser Poland was investigated. The analysis of physico–chemical and biological parameters demonstrated statistically significant differences between the three Fluvisols examined. While determining the metabolic potential of soil microbiomes with the use of the EcoPlate™ Biolog® technique, we also noted variation between the Fluvisols; however, they were arranged in a significantly different manner from other properties. The next generation sequencing method enabled us to determine the microorganisms common to three Fluvisols, and we identified bacteria specific to individual soils. These results corresponded with the data obtained through EcoPlate™, indicating that the structural diversity and metabolic potential of the microbiome does not always depend on soil quality parameters. Meanwhile, the increased structural diversity of the microbiome was found to improve the metabolic potential of soil microorganisms.

“…Enhanced specific activities of nitrogen-cycling enzymes accompanied by bacterial density-dependent behaviors in the rhizosphere soil suggest that AHL could be a control point in the complex process of rhizosphere nitrogen mineralization (DeAngelis et al, 2008; Lamers et al, 2012). Furthermore, AHL molecules can affect plant gene expression and physiological features such as growth rate, root development, and resistance to microbial pathogens (Scott et al, 2006; Ma et al, 2014). More recently, the presence of AHL signaling molecules in soil microbes can affect the production of extracellular hydrolytic enzymes, suggesting that AHLs may take part in population communications and co-exist behaviors, especially in plant and other complex environments (Crevelin et al, 2013; Jayaraman et al, 2014; Schikora et al, 2016; Venturi and Keel, 2016).…”

Mangrove rhizosphere environment harbors diverse populations of microbes, and some evidence showed that rhizobacteria behavior was regulated by quorum sensing (QS). Investigating the diverse profiles of QS molecules in mangrove ecosystems may shed light on the bacterial roles and lead to a better understanding of the symbiotic interactions between plants and microbes. The aims of the current study focus on identifying AI-1 type QS signals, i.e., acyl homoserine lactones (AHLs), in Kandelia obovata rhizosphere environment. Approximately 1200 rhizobacteria were screened and 184 strains (15.3%) tested were positive. Subsequent 16s rRNA gene sequencing and dereplication analyses identified 24 species from the positive isolates, which were affiliated to three different phyla, including Proteobacteria, Firmicutes, and Actinobacteria. Thin-layer chromatography separation of extracts revealed diverse AHL profiles and detected at least one active compound in the supernatant of these 24 cultivable AHL-producers. The active extracts from these bacterial isolates were further evaluated by ultra performance liquid chromatography-mass spectrometry, and the carbon side chain length ranged from C4 to C14. This is the first report on the diversity of AI-1 type auto-inducers in the mangrove plant K. obovata, and it is imperative to expand our knowledge of plant-bacteria interactions with respect to the maintenance of wetland ecosystem health.

“…Differences in the physicochemical properties and nutrient elements of soil inevitably affect crop quality and yield (Jun et al., 2021), and these differences depend to some extent on the biochemical processes of microbial activity in the soil ecosystem (Girvan et al., 2003). Studies have shown that soil physicochemical properties and soil‐forming parent materials, such as pH, salinity, and type, have a very important impact on the development of certain bacterial taxa (Ma et al., 2014).…”

In order to understand the relationship between rice (Oryza sativa L.) yield and the microbial communities and soil properties of different soil types, and to clarify the advantages of rice production characteristics of different soil types, we investigated the soil bacterial communities and soil properties of five representative rice soils (granitic sandy soil, purple clayey soil, red yellow clayey soil, yellow clayey soil, and alluvial sandy soil) and determined their effects on rice yield. The granitic sandy soil showed the greatest potential for increasing rice yield, with a yield of 39.2 g per plant, which was 24.56% higher than the lowest yielding soil type, these differences were related to differences in the soil microbial community and soil properties.There were significant differences in the microbial communities and chemical properties among the soil types, of which the granitic sandy soil type had the highest total nitrogen, available nitrogen, available kalium, and soil organic carbon contents, which were 2.60 g kg −1 , 196.07 mg kg −1 , 230.65 mg kg −1 , and 24.67 g kg −1 , respectively. Moreover, there was a significant correlation among specific bacterial taxa, soil properties, and rice yield, with Bacteroidetes showing a significant positive correlation with rice yield. The results also showed that pH, alkaline soluble nitrogen, and fast-acting potassium were the key soil properties affecting soil communities and rice yield. Both soil properties and soil microbial community influenced rice yield.
