“…Russula griseocarnosa is a wild, edible, medicinal, and ectomycorrhizal symbiont fungi distributed broadly in southern China (Yu et al, 2020). The fruiting bodies of R. griseocarnosa cannot be artificially cultivated (Chen et al, 2010;Ming et al, 2014). R. griseocarnosa has high economic value; its flesh has high nutritional value (Chen et al, 2010;Ming et al, 2014).…”

R. griseocarnosa polysaccharides have antioxidant activities (Ming et al, 2014) and inhibit the proliferation of cervical cancer cells (Yuan et al, 2017;Liu et al, 2018). Based on the location and the quality of R. griseocarnosa, the fruiting bodies of R. griseocarnosa can sell for $35-$45/kg, while dried of R. griseocarnosa are sold for $140-$180/kg (Ming et al, 2014), with prices increasing.…”

Russula griseocarnosa is a wild, ectomycorrhizal, edible, and medicinal fungus with high economic value in southern China. R. griseocarnosa fruiting bodies cannot be artificially cultivated. To better understand the effects of abiotic and biotic factors on R. griseocarnosa growth, the physicochemical properties of R. griseocarnosa and its associated bacterial communities were investigated in two soil types (mycosphere and bulk soil) from Fujian, Guangdong, and Guangxi Provinces. The results revealed that the diversity, community structure, and functional characteristics of the dominant mycosphere bacteria in all geographical locations were similar. Soil pH and available nitrogen (AN) are the major factors influencing the mycosphere-soil bacterial communities' structure. The diversity of soil bacteria is decreased in R. griseocarnosa mycosphere when compared with the bulk soil. Burkholderia-Paraburkholderia, Mycobacterium, Roseiarcus, Sorangium, Acidobacterium, and Singulisphaera may also be mycorrhiza helper bacteria (MHB) of R. griseocarnosa. The functional traits related to the two-component system, bacterial secretion system, tyrosine metabolism, biosynthesis of unsaturated fatty acids, and metabolism of cofactors and vitamins were more abundant in R. griseocarnosa mycosphere soil. The mycosphere soil bacteria of R. griseocarnosa play a key role in R. griseocarnosa growth. Application of management strategies, such as N fertilizer and microbial fertilizer containing MHB, may promote the conservation, propagation promotion, and sustainable utilization of R. griseocarnosa.

“…HPLC is a traditional method for detecting amino acids, but this method usually requires longer analysis time, larger samples consumption (Ming et al 2014;Zhao et al 2012;Meussen et al 2013). Compared with HPLC, CE is a powerful separation technique which could provide shorter analysis time, lower sample amount, fewer buffer consumption, and better separation efficiency (Frost et al 2010;Geiger et al 2012).…”

A simple capillary electrophoresis (CE) method that using β-cyclodextrin (β-CD) as buffer modifier has been developed for the detection of ten amino acids of jujube from five different geographical origins. The CE methodology was optimized through the variation of type, pH and concentration of the buffer solution, concentration of the additive β-CD, applied voltage, injection time and wavelength of the UV detection. It was found that the best separation of ten kinds of amino acids was achieved within less than 6 min under the optimum separation conditions: 50 mmol L-1 pH 9.5 borate-phosphate buffer with 5.0 mmol L-1 β-CD, 15 kV applied voltage, 25 °C column temperature, 210 nm detection wavelength, and 5 s injection time. This method showed good repeatability with RSD values of 1.4-3.4% for peak area, and 1.4-4.7% for migration time, when β-CD was used as buffer modifier. Under the optimum conditions, the method has been successfully applied to the detection of actual jujube samples, which also verifies the effectiveness and practicability of the method. Recovery of real samples was in ranging of 90%-105%, which proved the feasibility of the method. It also proved that the method was successfully applied to the quantitative analysis of amino acids of interest in plant samples.
