One of the contributing factors to this uncertainty is the lack of understanding about the role of rhizosphere priming effect (RPE) in shaping the temperature sensitivity. Using a novel continuous 13 C‐labeling method, we investigated the temperature sensitivity of RPE and its impact on the temperature sensitivity of SOM decomposition.

Implications of rhizosphere priming effects on SOM Rhizosphere interactions play a central role linking roots-soil system and regulate various aspects of nutrient cycling. Rhizodeposition inputs are known to change soil organic matter (SOM) decomposition via rhizosphere priming effects (RPEs) through enhancing soil biological activity and altering microbial community structure. The magnitude of RPEs varies widely among plant-species and root Soil moisture promoted the relatively high P availability at the higher altitudes with lower temperature via regulating citric acid, MBP, and NH 4 +-N. Future research should highlight the rhizosphere priming effects on the availability and transformation of soil P in order to better understand the biogeochemical cycling of P and the underlying 2009-09-01 2017-08-01 In the presence of plants, a priming effect occurs in the direct vicinity of the living roots, and it is called rhizosphere priming effect (RPE). Plant‐mediated and environmental … Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown. This study aimed to link species variation in RPE with plant traits and rhizosphere properties. Rhizosphere effects can induce an increase or decrease in the decomposition of soil organic carbon (SOC), which is frequently referred to as a positive or negative rhizosphere priming effect (RPE).

This study aimed to link species variation in RPE with plant traits and rhizosphere properties. The change in native soil organic carbon (SOC) decomposition caused by plant roots or the rhizosphere priming effect (RPE) is a common phenomenon. Although most of the SOC is stored in aggregates with different size classes, the RPE in aggregates and the underlying mechanisms remain unclear. Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown. This study aimed to link species variation in RPE with plant traits and rhizosphere properties. Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown. This study aimed to link species variation in RPE with plant traits and rhizosphere properties.

Here, we provide quantitative evidence of a strong coupling between root exudation, SOM decomposition, and release of plant available N caused by rhizosphere priming effects. As plants tend to increase belowground C allocation with increased temperatures and CO(2) concentrations, priming effects need to be considered in our long-term analysis of soil C budgets in a changing environment.

The soil was Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown. This study aimed to link species variation in RPE with plant traits and rhizosphere properties.

Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown. This study aimed to link species variation in RPE with plant traits and rhizosphere properties.

Although most of the SOC is stored in aggregates with different size classes, the RPE in aggregates and the underlying mechanisms remain unclear. Rhizosphere priming is the change in decomposition of soil organic matter (SOM) caused by root activity.

It is now becoming generally recognized that rhizosphere priming effects on SOC decomposition can play important roles in the global carbon cycle (Heimann and Reichstein, 2008, Kuzyakov, 2010, Cheng et al., 2014). The actual mechanisms underlying rhizosphere priming effects still remain elusive (Kuzyakov, 2002, Cheng and Kuzyakov, 2005). Rhizosphere priming may be affected by soil nutrient availability, but rhizosphere priming itself can also affect nutrient supply to plants.

Using a novel continuous 13 C‐labeling method, we investigated the temperature sensitivity of RPE and its impact on the temperature sensitivity of SOM decomposition. Rhizosphere priming effects (RPEs) play a central role in modifying soil organic matter mineralization. However, effects of tree species and intraspecific competition on RPEs … 2017-09-08 2002-01-01 2020-05-01 The relationship between the rhizosphere priming effect (RPE) and selected variables was quantified by conducting multiple regression analyses, with the most significant … microorganism leading to high rhizosphere priming effect compared to the other treatments. The higher rhizosphere priming effect explained the greatest CO 2 efflux under well-watered treatment in comparison to the drought-stressed and the control.

negative priming effect, has also been observed (Cheng, 1996; Bader and Cheng, 2007). Although rhizosphere priming effects have frequently been reported in a variety of soil-plant systems, the mechanisms behind these effects remain unclear (Kuzyakov, 2010).

The advent of stable isotope analysis makes it possible to study priming effects in environments receiving semicontinuous inputs of C, such as the rhizosphere, as well as to distinguishing between real and apparent priming. 2021-02-21 · It is known that nitrogen (N) input modulates the rhizosphere priming effect (RPE); however, the magnitude and driving mechanisms of priming under increasing rates of fertilizer application remain unclear.
