Ammonium sulfate, as the primary leaching agent, has caused significant nitrogen pollution in rare earth elements (REEs) mining areas. Phytoremediation is a promising remediation method, relying on the synergistic relationships between plants and their root-associated microbiome. Nevertheless, harnessing the microbiome to accelerate nitrogen transformation and absorption by plants is challenging.

However, the interactions between the Huanglongbing (HLB) pathogen and endosymbiotic bacteria within the Asian citrus psyllid (ACP, Kuwayama) in wild populations remain elusive. Thus, this study aimed to detect the infection rates of HLB in the ACP across five localities in China, with a widespread prevalence in Ruijin (RJ, 58%), Huidong (HD, 28%), and Lingui (LG, 15%) populations.

However, little is known about the factors that drive the differentiation of bacterial lifestyles, especially in flooding lake systems. Here we assessed the compositional and functional similarities between the FL and PA bacterial fractions in a typical flooding lake-the Poyang Lake (PYL) of China.

For migratory birds, long-distance traveling poses selection pressures on their gut microbiota, ultimately affecting the birds' health, fitness, ecology, and evolution. However, our understanding of mechanisms that underlie the assembly of the gut microbiome of migratory birds is limited.

The difficulty remained in how the "COVID pass" from different countries and regions could be mutually recognised. This study surveys the current practice of COVID-19 vaccination certificates in 12 representative countries/regions around the world and provides a comprehensive mapping of the vaccination certificates in these countries/regions.

In this study, a machine learning model based on nasal airflow and respiratory effort of the chest and abdomen is proposed to automatically identify respiratory events, including normal breathing, hypopnea and apnea.The nasal airflow and chest-abdominal respiratory effort signals were collected by polysomnography (PSG).

Despite the rapid development, there has been no standardized framework allowing for the reliable and valid measurement of interpreting competence in China. Against this background, the China Standards of English (CSE), which are the Chinese counterpart to the Common European Framework of Reference (CEFR), were unveiled in 2018 after 4 years of government-funded research and validation.

It lasted for 36 months and was divided into three main stages: initiation of gonad formation, a stable growth phase, and a reproductive cell development phase. Each reproductive cycle consisted of five stages: proliferative stage (from late January to late February), growth stage (from late February to late March), maturation stage, spawning stage (from early April to late October) and recovery stage (from early November to late January).

However, hemorrhagic disease caused by grass carp reovirus (GCRV) results in a tremendous loss in the process of grass carp cultivation. Transcriptome analysis could provide a comprehensive understanding of the molecular mechanisms involved in specific biological processes and diseases for the resistance to reovirus infection of grass carp.

Similar to the mammalian counterparts, fish JAK1 and TYK2 also perform their potential biological activities by phosphorylating cytokine receptors and STAT. In the present study, Ctenopharyngodon idellus JAK1 (CiJAK1) and TYK2 (CiTYK2) were cloned and identified.

There are many ADAR1 splicing isoforms in mammals, including an interferon (IFN) inducible ∼150 kD protein (ADAR1-p150) and a constitutively expressed ∼110 kD protein (ADAR1-p110). The structural diversity of ADAR1 splicing isoforms may reflect their multiple functions.

PKR is a dsRNA binding protein with a dsRBD and a kinase domain (KD). dsRBD is mostly composed of two (in mammal PKR) or three (in some fish PKR) dsRNA binding motifs (dsRBMs).

Catalyzing the deamination of adenosine to inosine in RNA, ADAR1 (adenosine deaminase that act on RNA 1) belongs to ADAR family. In our previous work, we have cloned the complete genomic sequence of ADAR1 from grass carp (Ctenopharyngodon idella), named CiADAR1. In the process, we found a splicing isoform of CiADAR1 (CiADAR1-like).

Fish type I IFN receptor, a kind of enzyme-linked receptor, consists of two subunits and belongs to the class II cytokine receptor family B (CRFB). In the present study, we cloned and identified two putative grass carp (Ctenopharyngodon idella) type I interferon receptor subunits (termed CiCRFB1 and CiCRFB5) by homology cloning techniques.
