Inhibition of litter decomposition of two emergent macrophytes by addition of aromatic plant powder

Abstract

Aromatic plants show antimicrobial activity due to their essential oils, but their effect on litter decomposition is unclear. In this study, we evaluated the biomass loss and nutrient dynamics in leaf litters of two macrophytes (Miscanthus sacchariflorus and Carex brevicuspis) with and without addition of powdered material of the aromatic plant Polygonum hydropiper or the non-aromatic plant C. brevicuspis. The two powders had similar basic chemical qualities but P. hydropiperi had a higher essential oils concentration. Leaf litters of M. sacchariflorus and C. brevicuspis were incubated with powdered P. hydropiper or C. brevicuspis (500 g m−3, 250 g m−3, and no addition) for 120 days in a mesocosm experiment. Compared with the control (no addition), P. hydropiperi addition decelerated nutrient release and litter decomposition, while C. brevicuspis addition accelerated those processes. The nitrogen concentrations in both leaf litters and the phosphorus concentration in C. brevicuspis leaf litter were increased by addition of both plant powders. The fungal biomass in both leaf litters decreased after P. hydropiperi addition, due to the antifungal activity of its essential oils. These data indicate that the aromatic plant P. hydropiperi inhibits litter decomposition via its essential oils and that such inhibition is not species-specific.

Advances in mass spectrometry‐based glycoproteomics

“…Although researchers have turned to the world of nanomaterials because of their superior physicochemical characteristics and variety of functionalized nanomaterials for the enrichment of glycopeptides have been reported , there are still challenges to utilize these materials in routine laboratories. Most of these functionalized materials (e.g., Fe 3 O 4 @DA@MOF , MOF@Au‐cysteine , ZICF‐PAMAM , and GO@Fe 3 O 4 @SiO 2 @PAMAM@maltose ) are not commercially available and suffers from time‐consuming, tedious, and multistep fabrication. Moreover, separation from the mixtures is the parameter that should be carefully considered when using nanomaterials for enrichment.…”

“…Xie et al [43] synthesized a hydrophilic magnetic amino-functionalized MOF which permitted selective enrichment of glycopeptides. The sorbent was synthesized by initially preparing Fe 3 O 4 nanoparticles at high temperature (265°C) in phenyl ether as a solvent.…”

“…This MOF material exhibited excellent binding capacity, good selectivity, high recovery, and low detection limit, allowing the identification of 1069 N -glycopeptides corresponding to 614 N -glycoproteins in HeLa cells. Although both of the abovementioned studies [43, 44] suggested that functionalized MOFs can be used as a sorbent for glycopeptide enrichment, routine use of such material is limited by the fact that the synthesis of MOFs is time-consuming, tedious, and expensive.…”

“…The recent advancement in the fields of glycoprotein enrichment based on using new functionalized materials was summarized. Although researchers have turned to the world of nanomaterials because of their superior physicochemical characteristics and variety of functionalized nanomaterials for the enrichment of glycopeptides have been reported [43–46, 51, 52, 54–56, 62–66], there are still challenges to utilize these materials in routine laboratories. Most of these functionalized materials (e.g.…”

Facile Preparation of Hydrophilic Dual Functional Magnetic Metal‐Organic Frameworks as a Platform for Proteomics Research

“…The advantages of MOFs make them promising materials, combining the hydrophilic interaction and IMAC techniques for glycopeptides and phosphopeptides enrichment. Magnetic MOF‐IMAC materials have been reported before, the work was very meaningful and attractive, but the magnetic MOF‐IMAC materials can still be improvement. So design a perfect magnetic MOF to enrich both glycopeptides and phosphopeptides is fascinating, it would be interesting and meaningful to develop such a material with dual functions.…”
