The effects of afforestation on soil bacterial communities in temperate grassland are modulated by soil chemical propertiesPeerJ - Tập 7 - Trang e6147
Shuhong Wu, Bing Huang, Jian Gao, Siqi Wang, Pei‐Chun Liao
Grassland afforestation dramatically affects the abiotic, biotic, and ecological function properties of the original ecosystems. Interference from afforestation might disrupt the stasis of soil physicochemical properties and the dynamic balance of microbiota. Some studies have suggested low sensitivity of soil properties and bacterial community to afforestation, but the apparent lack of a ...... hiện toàn bộ
GMPR: A robust normalization method for zero-inflated count data with application to microbiome sequencing dataPeerJ - Tập 6 - Trang e4600
Li Chen, James Reeve, Lujun Zhang, Nancy Y. Ip, Xuefeng Wang, Jun Chen
Normalization is the first critical step in microbiome sequencing data analysis used to account for variable library sizes. Current RNA-Seq based normalization methods that have been adapted for microbiome data fail to consider the unique characteristics of microbiome data, which contain a vast number of zeros due to the physical absence or under-sampling of the microbes. Normalization met...... hiện toàn bộ
Determining relevant traits for selecting landrace accessions of Phaseolus lunatus L. for insect resistancePeerJ - Tập 9 - Trang e12088

Plant-insect interactions are a determining factor for sustainable crop production. Although plants can resist or tolerate herbivorous insects to varying degrees, even with the use of pesticides, insects can reduce plant net productivity by as much as 20%, so sustainable strategies for pest control with less dependence on chemicals are needed. Selecting plants with optimal resistance and p...... hiện toàn bộ
Characterization of cold stress responses in different rapeseed ecotypes based on metabolomics and transcriptomics analysesPeerJ - Tập 8 - Trang e8704

The winter oilseed ecotype is more tolerant to low temperature than the spring ecotype. Transcriptome and metabolome analyses of leaf samples of five spring Brassica napus L. (B. napus) ecotype lines and five winter B. napus ecotype lines treated at 4 °C and 28 °C were performed. A total of 25,460 differential...... hiện toàn bộ
East palearctic treefrog past and present habitat suitability using ecological niche modelsPeerJ - Tập 10 - Trang e12999

Ecological niche modeling is a tool used to determine current potential species’ distribution or habitat suitability models which can then be used to project suitable areas in time. Projections of suitability into past climates can identify locations of climate refugia, or areas with high climatic stability likely to contain the highest levels of genetic diversity and stable populations wh...... hiện toàn bộ

CTLA-4 polymorphisms associate with breast cancer susceptibility in Asians: a meta-analysisPeerJ - Tập 5 - Trang e2815

Previous studies have investigated the association between cytotoxic T-lymphocyte antigen-4 (CTLA-4) polymorphisms and breast cancer susceptibility, but the results remained inconsistent. Therefore, we evaluated the relationship between four common CTLA-4 polymorphisms and breast cancer risk by a meta-analysis, aiming to derive a compre...... hiện toàn bộ
Air transportation, population density and temperature predict the spread of COVID-19 in BrazilPeerJ - Tập 8 - Trang e9322

There is evidence that COVID-19, the disease caused by the betacoronavirus SARS-CoV-2, is sensitive to environmental conditions. However, such conditions often correlate with demographic and socioeconomic factors at larger spatial extents, which could confound this inference. We evaluated the effect of meteorological conditions (temperature, solar radiation, air humidity and precipitation)...... hiện toàn bộ
