“…Nylon litterbags (0.3-mm mesh size, 5 × 10 cm lled with 1 g of litter of A. thaliana) were used for the incubation experiment to prevent litter being chewed by soil fauna (Tian et al 2018). Litterbags were placed at the depth of 5 cm beneath the soil surface to mimic standard eld decomposition condition.…”

“…We assayed the potential activities of nine extracellular enzymes involved in litter C and nutrient cycling (Talbot et al 2012;Tian et al 2018), including cellobiohydrolase (CBH1 71123), β-1,4-glucosidase (BG), β-1,4-xylosidase (BX), nitrate reductase (NR), urease (URE), acid phosphatase (ACP), alkaline phosphatase (ALP), peroxidase (POD) and phenol oxidase (Phox). Detailed descriptions of the assay methods were referred to Tian et al (2018), the detail description is available in the supplement le. (Caporaso et al 2011, Apprill et al 2015, and primer set ITS1F (5'-CTTGGTCATTTAGAGGAAGTAA-3') and ITS2R (5'-GCTGCGTTCTTCATCGATGC-3') was used to amplify the Internal Transcribed Spacer 1 (ITS1) of fungi (Xiong et al, 2017), which were selected for many large-scale microbiomes sequencing.…”

“…Total C and N concentration of litter were determined using an elemental analyzer (Elemental Vario Micro, Germany) (Jia et al 2015;Tian et al 2018). Organic matter content was measured after igniting the dry samples for 5 h at 550°C (Täumer et al 2005).…”

Background and aims: Endophytic microorganisms exist commonly in plants and are recognized to increase plant growth especially under adverse physical environmental conditions. We here demonstrate that endophytic bacteria (EB) Bacillus cereus can accelerate the decomposition of plant litter and enhance nutrient availability for plant growth.Methods: We first obtained plant litter with and without EB inoculation using a model plant Arabidopsis thaliana in a microcosmic experiment, then conducted a litter decomposition experiment to investigated the effect of EB on litter decay rate, phosphorus availability, and on soil microbial community structure. We further evaluated wheat (Triticum aestivum) biomass growth using soils treated with and without EB.Results: Inoculation of EB significantly increased the mass loss of Arabidopsis litter in the middle stage of decomposition, elevated the activity of alkaline phosphatase in the early stage of decomposition, and increased soil available P at the end of decomposition. Analyses of Illumina MiSeq sequencing and structural equation models also indicated that EB inoculation had pronounced impact on the bacterial abundance and diversity in soil. Finally, the growth of the wheat was significantly promoted in the litter with EB decomposition system. Conclusion: EB mediated host after-life effect likely through accelerating the release of nutrients such as P from decomposing plant litter and regulating the structure of soil microorganisms, promoting the sustainability of nutrient utilization efficiency in a terrestrial ecosystem.

“…In many "home vs away" studies, plants perform better when grown with soil from the same region as the plant [56][57][58]. Moreover, decomposition rate is increased when a plant litter is sympatric to the soil compared to allopatric soils [59,60]. Since plant-microbe interactions heavily depend on genotypic differences [61] and resource availability [40,62], microbial communities under native plants may differ compared to common cultivar cover crops, leading to differences in ecosystem services and possibly the suppression of pathogens.…”

Cover Crop Diversity as a Tool to Mitigate Vine Decline and Reduce Pathogens in Vineyard Soils

et al. 2020

Wine grape production is an important economic asset in many nations; however, a significant proportion of vines succumb to grapevine trunk pathogens, reducing yields and causing economic losses. Cover crops, plants that are grown in addition to main crops in order to maintain and enhance soil composition, may also serve as a line of defense against these fungal pathogens by producing volatile root exudates and/or harboring suppressive microbes. We tested whether cover crop diversity reduced disease symptoms and pathogen abundance. In two greenhouse experiments, we inoculated soil with a 106 conidia suspension of Ilyonectria liriodendri, a pathogenic fungus, then conditioned soil with cover crops for several months to investigate changes in pathogen abundance and fungal communities. After removal of cover crops, Chardonnay cuttings were grown in the same soil to assess disease symptoms. When grown alone, white mustard was the only cover crop associated with reductions in necrotic root damage and abundance of Ilyonectria. The suppressive effects of white mustard largely disappeared when paired with other cover crops. In this study, plant identity was more important than diversity when controlling for fungal pathogens in vineyards. This research aligns with other literature describing the suppressive potential of white mustard in vineyards.

“…In general, the contribution of plant roots on decomposition activity in the soil and plant-soil feedback has been overlooked in the literature , Zhang et al 2016b). Yet, a recent study has shown that the presence of local roots may not only stimulate decomposition but also mediate specific litter-decomposer interactions (Tian et al 2018). Thus, more research would be needed to investigate to what extent there are differences in the role of specialized decomposers for decomposition of above and belowground litter, as root decomposability is expected to differ substantially from shoot litter (Birouste et al 2012, Freschet et al 2013, and to determine how dominant plant species may influence the role of specialized decomposers.…”
