Abstract:

The interaction of plants and microorganisms in the rhizospheres and non-rhizospheres of plants is well studied and mastered in the terrestrial environment. In general, given the rhizosphere effect exclusively defining the effectiveness of root exudates to promote multiplication, development and microbial growth in the rhizosphere zones, studies unanimously tend to report that the microbial biomass is rather high in the rhizosphere than in the non-rhizosphere. However, the trend may change in the marine environment. This study was conducted in both the rhizosphere and non-rhizosphere of the ma

Abstract:

Background: Peanut (Arachis hypogaea L.), an important oilseed and food legume, is widely cultivated in the semi-arid tropics. Drought is the major stress in this region which limits productivity. Microbial communities in the rhizosphere are of special importance to stress tolerance. However, relatively little is known about the relationship between drought and microbial communities in peanuts. Method: In this study, deep sequencing of the V3-V4 region of the 16S rRNA gene was performed to characterize the microbial community structure of drought-treated and untreated peanuts.

Abstract:

Background Soil compaction can be mitigated by deep tillage and subsoiling practices following a long period of no-tillage. Fallow tillage rotation methods are frequently used to improve water availability in the soils of the southeastern Loess Plateau region of China. Rhizosphere soil bacteria are ecologically important for the transformation of matter and energy in the plant root system and can be influenced by tillage rotation treatments. However, the effect of tillage rotations on the bacterial community and structure of rhizosphere soil is not well understood. Methods A two-year field exp

Abstract:

The production of wheat is fundamentally interconnected with worldwide food security. The practice of deep tillage (DT) cultivation has shown advantages in terms of soil enhancement and the mitigation of diseases and weed abundance. Nevertheless, the specific mechanisms behind these advantages are unclear. Accordingly, we aimed to clarify the influence of DT on rhizosphere soil (RS) microbial communities and its possible contribution to the improvement of soil quality. Soil fertility was evaluated by analyzing several soil characteristics. High-throughput sequencing techniques were utilized to

Abstract:

Vegetation simultaneously drives transpiration, a significant component of the hydrological balance, and stimulates the breakdown of bedrock and formation of soil. Together these actions impact both the magnitude of streamflow and the chemical or solute load of the stream. Yet, it is still unknown under what conditions deeply rooted plants enhance or impede chemical weathering of rocks. An unestablished link at the heart of this gap in knowledge are the ways in which coupling between plant water demand, plant nutrient demand and recycling of these elements through the ecosystem manifest in the

Bedrock mineral breakdown in mountainous landscapes sustains long-term atmospheric CO₂ drawdown and releases solutes that sustain ecosystems and set the chemistry of upland stream water. In the unsaturated Bedrock Vadose Zone (BVZ) of hillslopes, minerals, water, reactive gases, and deep roots interact to produce a hotspot of these weathering reactions. New evidence suggests that, in the BVZ, rock moisture sustains evapotranspiration, while deep roots drive deep CO₂ production.

Pseudomonas spp. have great potential as rhizosphere bacteria that stimulate plant growth (PGPR), and also have mycostatic activity against phytopathogenic fungi, therefore this type of microorganisms is of great interest for the creation of biological products with high efficiency for different plant species. The purpose of this work was to study strains of Pseudomonas sp. with fungistatic activity, retain the ability to suppress the growth of phytopathogenic fungal strains Microdochium nivale VKM 3106, Fusarium graminearum VKM 1668, Fusarium culmorum VKM 844 and Bipolaris sorokiniana after l

Abstract:

Hydrangea macrophylla exhibiting blue sepals (versus purple or pink) have improved marketability; however, little research has been conducted to evaluate aluminum (Al), the element responsible for bluing, on crop growth, effectiveness of bluing sepals, and characteristics of flower clusters in an outdoor nursery. This study compared substrate Al availability, crop growth, flower color, number, and size over a 56-week period in two locations. A polymer coated (90-day release) or ground aluminum sulfate [Al2(SO4)3; water soluble] was either incorporated into a non-limed pine bark substrate, appl

Abstract:

Diazotrophic bacteria isolated from the rhizosphere of a wild wheat ancestor, grown from its refuge area in the Fertile Crescent, were found to be efficient Plant Growth-Promoting Rhizobacteria (PGPR), upon interaction with an elite wheat cultivar. In nitrogen-starved plants, they increased the amount of nitrogen in the seed crop (per plant) by about twofold. A bacterial growth medium was developed to investigate the effects of bacterial exudates on root development in the elite cultivar, and to analyze the exo-metabolomes and exo-proteomes. Altered root development was observed, with distinct

Symbiosis is formed in the form of an exchange between nutrients and carbohydrates and helps plants absorb P. elements. In Kalimantan, sengon often used as industrial material because it is fast-growing species and widely cultivated by the community. Sengon is a common species planted in mineral soils; however, due to the rising demand of sengon timber, it has been planted on peatlands. This study aims to compare the abu
