Drought is an abiotic stress that affects plant growth, and lipids are the main economic factor in the agricultural production of oil crops. However, the molecular mechanisms of drought response function in lipid metabolism remain little known. In this study, overexpression (OE) of different copies of the drought response genes LEA3 and VOC enhance...
GMrepo (data repository for Gut Microbiota) is a database of curated and consistently annotated human gut metagenomes. Its main purpose is to facilitate the reusability and accessibility of the rapidly growing human metagenomic data. This is achieved by consistently annotating the microbial contents of collected samples using state-of-art toolsets...
Background:
Compromised intestinal barrier (CIB) has been associated with many enteropathies, including colorectal cancer (CRC) and inflammatory bowel disease (IBD). We hypothesized that CIB could lead to increased host-derived contents including epithelial cells into the gut, change its physio-metabolic properties, and globally alter microbial co...
Extrachromosomal mobile genetic elements (eMGEs), including phages and plasmids, that can move across different microbes, play important roles in genome evolution and shaping the structure of microbial communities. However, we still know very little about eMGEs, especially their abundances, distributions and putative functions in microbiomes. Thus,...
Genetic variations are instrumental for unraveling phage evolution and deciphering their functional implications. Here, we explore the underlying fine-scale genetic variations in the gut phageome, especially structural variations (SVs). By using virome-enriched long-read metagenomic sequencing across 91 individuals, we identified a total of 14,438...
Current metagenome assembled human gut phage catalogs contained mostly fragmented genomes. Here, comprehensive gut virome detection procedure is developed involving virus‐like particle (VLP) enrichment from ≈500 g feces and combined sequencing of short‐ and long‐read. Applied to 135 samples, a Chinese Gut Virome Catalog (CHGV) is assembled consisti...
Background
The fungal component of the human gut microbiome, also known as the mycobiome, plays a vital role in intestinal ecology and human health. However, the overall structure of the gut mycobiome as well as the inter-individual variations in fungal composition remains largely unknown. In this study, we collected a total of 3363 fungal sequenci...

The fungal component of the human gut microbiome, also known as the mycobiome, plays a vital role in intestinal ecology and human health. Here, we identify and characterize four mycobiome enterotypes using ITS profiling of 3,363 samples from 16 cohorts across three continents, including 572 newly profiled samples from China. These enterotypes exhib...
Evaluating the quality of metagenomic assemblies is important for constructing reliable metagenome-assembled genomes and downstream analyses. Here, we present metaMIC (https://github.com/ZhaoXM-Lab/metaMIC), a machine learning-based tool for identifying and correcting misassemblies in metagenomic assemblies. Benchmarking results on both simulated a...
Known gut virus diversity is currently skewed by challenges in fecal virus-like particles (VLPs) enrichment and towards active viruses detectable in shotgun metagenomic sequencing. Here, we apply a virus detection procedure, including vigorous enrichment to harvest large quantity of VLPs, and combined Illumina and PacBio sequencing, to fecal sample...

Background
Despite recent efforts, a single factor underlying the gut microbiota dysbiosis in intestinal diseases is not identified. We hypothesized that compromised intestinal barrier (CIB) could lead to increased host-derived contents including human cells in the gut, change its physio-metabolic properties, and globally alter gut microbiota and t...
