Filamentous fungi have wide applications in biotechnology. The CRISPR/Cas9 system is a powerful genome-editing method that facilitates genetic alterations of genomes in a variety of organisms. However, a genome-editing approach has not been reported in filamentous fungi. Here, we demonstrated the establishment of a CRISPR/Cas9 system in the filamentous(More)
Integration plasmids are often used in constructing chromosomal mutations, as it enables the alternation of genes at any location by integration or replacement. Food-grade integration vectors can integrate into the host genome without introducing any selectable markers or residual bases, and the recombination often happens in non-coding region. In this(More)
The role of muramyl dipeptide (MDP) and tuftsin in oral immune adjustment remains unclear, particularly in a Lactobacillus casei (L. casei) vaccine. To address this, we investigated the effects of different repetitive peptides expressed by L. casei, specifically the MDP and tuftsin fusion protein (MT) repeated 20 and 40 times (20MT and 40MT), in mice also(More)
Avian reticuloendotheliosis virus (REV) infection can induce a runting syndrome, immunosuppression, acute reticulum cell neoplasia and lymphomas in a variety of domestic and wild birds. To evaluate the pathogenicity and oncogenicity of REV-JX0927 that isolated from Chinese partridge, experimental inoculated day-old specific-pathogen-free (SPF) White Leghorn(More)
BACKGROUND Trichoderma reesei is the preferred organism for producing industrial cellulases. However, a more efficient heterologous expression system for enzymes from different organism is needed to further improve its cellulase mixture. The strong cbh1 promoter of T. reesei is frequently used in heterologous expression, however, the carbon catabolite(More)
To evaluate the immune responses of recombinant Lactobacillus casei 393 expressing Porcine Epidemic Diarrhea Viral (PEDV) N protein as oral vaccine, n gene of PEDV was subcloned into the expression vector pPG-1, and then transformed into L. casei 393 by electroporation, resulting in recombinant strain pPG-1-n/L, casei 393. The recombinant strains were(More)
Single-nucleotide polymorphisms (SNPs) are the most frequent form of genetic variations. Non-synonymous SNPs (nsSNPs) occurring in coding region result in single amino acid substitutions that associate with human hereditary diseases. Plenty of approaches were designed for distinguishing deleterious from neutral nsSNPs based on sequence level information.(More)
Emaciation, depression and lethargy were observed in two flocks of Chinese local breed and one flock of commercial layer chicken infected naturally from 2010 to 2011. The aims of this study were to diagnose. Gross observation showed that severe enlargement of liver, spleen and kidney, and hemorrhage of thymus, muscle and glandular stomach in all submitted(More)
Transmissible gastroenteritis coronavirus (TGEV) is a member of the genus Coronavirus, family Coronaviridae, order Nidovirales. TGEV is an enteropathogenic coronavirus that causes highly fatal acute diarrhoea in newborn pigs. An oral Lactobacillus casei (L. casei) vaccine against anti-transmissible gastroenteritis virus developed in our laboratory was used(More)
