Here, we describe the use of monolayers of intestinal epithelial cells derived from intestinal organoids and transcriptomics to investigate the direct effects of dietary protein sources on epithelial function. Mechanically dissociated 3 D organoids of mouse duodenum were used to generate a polarized epithelium containing all cell types found in the tissue of origin. The organoid-derived cell monolayers were exposed to 4%(w/v) of ‘undigested(non-hydrolysed)-soluble' fraction of protein sources used as feed ingredients [soybean meal(SBM) and casein], or alternative protein sources(spray dried plasma protein, and yellow meal worm), or controls for 6 h prior to RNA isolation and transcriptomics. All protein sources altered expression of unique biological processes in the epithelial cells. Exposure of intestinal organoids to SBM downregulated expression of retinol and retinoid metabolic processes as well as cholesterol and lipid biosynthetic pathways, consistent with the reported hypotriglyceridaemic effect of soy protein in vivo. These findings support the use of intestinal organoids as models to evaluate complex interactions between dietary ingredients and the intestinal epithelium and highlights some unique host effects of alternative protein sources in animal feed and potentially human food.

Metabolic responses of Eucalyptus species to different temperature regimes

引用

Journal of Integrative Plant Biology 2018年第5期60卷 397-411页

Species and hybrids of Eucalyptus are the world＇s most widely planted hardwood trees. They are cultivated across a wide range of latitudes and therefore environmen- tal conditions. In this context, comprehensive metabolo- mics approaches have been used to assess how different temperature regimes may affect the metabolism of three species of Eucalyptus, E. dunnii, E. grandis and E. pellita. Young plants were grown for 53 d in the greenhouse and then transferred to growth chambers at 10℃, 20℃ or 30℃ for another 7 d. In all three species the leaf chlorophyll content was positively correlated to temperature, and in E. pellita the highest temperature also resulted in a significant increase in stem biomass. Comprehensive metabolomics was performed using untargeted gas chromatography mass spectrometry （GC-MS） and liquid chromatography （LC）-MS. This approach enabled the comparison of the relative abundance of 88 polar primary metabolites from GC-MS and 625 semi-polar secondary metabolites from LC-MS. Using principal components analysis, a major effect of tempera- ture was observed in each species which was larger than that resulting from the genetic background. Compounds mostly affected by temperature treatment were subsequently selected using partial least squares discriminant analysis and were further identified. These putative annotations indicated that soluble sugars and several polyphenols, including tannins, triterpenes and alkaloids were mostly influenced.

The Characteristics and Parameterization of Aerodynamic Roughness Length over Heterogeneous Surfaces

Aerodynamic roughness length （Z0m） is a key factor in surface flux estimations with remote sensing algorithms and/or land surface models. This paper calculates ZOrn over several land surfaces, with 3 years of experimental data from Xiaotangshan. The results show that Z0m is direction-dependent, mainly due to the heterogeneity of the size and spatial distribution of the roughness elements inside the source area along different wind directions. Furthermore, a heuristic parameterization of the aerodynamic roughness length for heterogeneous surfaces is proposed. Individual Z0m over each surface component （patch） is calculated firstly with the characteristic parameters of the roughness elements （vegetation height, leaf area index, etc.）, then Z0m over the whole experimental field is aggregated, using the footprint weighting method.

Transcriptional responses of Brassica nigra to feeding by specialist insects of different feeding guilds

引用

Insect Science 2011年第3期18卷 259-272页

作者： Colette Broekgaarden Roeland E. Voorrips Marcel Dicke Ben Vosman wageningen UR Plant Breeding Plant Research International B.V. Wageningen Laboratory of Entomology Wageningen University Wageningen the Netherlands

Plants show phenotypic changes when challenged with herbivorous insects. The mechanisms underlying these changes include the activation of transcriptional responses, which are dependent on the attacking insect. Most transcriptomic studies on crucifer-insect interactions have focused on the model plant Arabidopsis thaliana, a species that faces low herbivore pressure in nature. Here, we study the transcriptional responses of plants from a wild black mustard （Brassica nigra） population to herbivores of different feeding guilds using an A. thaliana-based whole-genome microarray that has previously been shown to be suitable for transcriptomic analyses in Brassica. Transcriptional responses of B. nigra after infestation with either Pieris rapae caterpillars or Brevicoryne brassicae aphids are analyzed and compared. Additionally, the insect-induced expression changes of some individual genes are analyzed through quantitative real-time polymerase chain reaction. The results show that feeding by both insect species results in the accumulation of transcripts encoding proteins involved in the detoxification of reactive oxygen species, defensive proteins and glucosinolates and this is correlated with experimental evidence in the literature on such biochemical effects. Although genes encoding proteins involved in similar processes are regulated by both insects, there was little overlap in the induction or repression of individual genes. Furthermore, P. rapae and B. brassicae seem to affect different phytohormone signaling pathways. In conclusion, our results indicate that B. nigra activates several defense-related genes in response to P rapae or B. brassicae feeding, but that the response is dependent on the attacking insect species.

Understanding Genetic Load in Potato for Hybrid Diploid Breeding

Molecular Plant 2019年第7期12卷 896-898页

作者： Christian W.B.Bachem Herman J.van Eck Michiel E.de Vries Plant Breeding Wageningen University and Research Wageningen the Netherlands Solynta Wageningen the Netherlands

Recently, Zhang et al.(2019) have managed to provide abundant evidence to support long-held theories regarding mechanisms of inbreeding depression and potential effects of heterosis that are likely to have a considerable impact on potato breeding in the future (Figure 1). Despite its large genetic variation regarding yield, harvest index, and water use efficiency, potato breeding has attained only negligible advances in the most important breeding goals such as yield, tuber quality, and abiotic stress tolerance, and only modest progress in pathogen resistance. This low level of improvement is clearly due to the complexity of breeding a heterozygous tetraploid outbreeder rather than to the lack of genetic potential available in wild and cultivated material. In contrast, breeding at the diploid level, in particular in combination with self-compatibility, will allow the fixation of beneficial alleles to homozygosity.
