The arms race between bacteria and phages led to the development of sophisticated antiphage defense systems, including CRISPR-Cas and restriction-modification systems. Evidence suggests that unknown defense systems are located in “defense islands” in microbial genomes. We comprehensively characterized the bacterial defensive arsenal by examining gene families that are clustered next to known defense genes in prokaryotic genomes. Candidate defense systems were systematically engineered and valida...

Abstract MicroRNAs (miRNA) regulate multiple physiological processes including development and metamorphosis in insects. In the current study, we demonstrate that a conserved invertebrate miRNA-14 (miR-14) plays an important role in ecdysteroid regulated development in the silkworm Bombyx mori, a lepidopteran model insect. Ubiquitous transgenic overexpression of miR-14 using the GAL4/UAS system resulted in delayed silkworm larval development and smaller body size of larva and pupa with decrease ...

Abstract The custom-design bacterial CRISPR/Cas9 system has been recently used in some insects, indicating a powerful technique for studies on gene function and transgenic insects. However, its use in lepidopteran pests is scarce. Here, we reported a CRISPR/Cas9 system mediated mutagenesis of biogenesis of lysosome-related organelles complex1, subunit 2 ( BLOS2 ) gene in a noctuid pest Spodoptera litura. A fragment of SlitBLOS2 was identified by analyzing a S. litura transcriptome database by lo...

β-Thalassemia is a global health issue, caused by mutations in the HBB gene. Among these mutations, HBB −28 (A>G) mutations is one of the three most common mutations in China and Southeast Asia patients with β-thalassemia. Correcting this mutation in human embryos may prevent the disease being passed onto future generations and cure anemia. Here we report the first study using base editor (BE) system to correct disease mutant in human embryos. Firstly, we produced a 293T cell line with an exogen...

The genetic basis of body shape and coloration patterns on caterpillars is often assumed to be regulated separately, but it is possible that common molecules affect both types of trait simultaneously. Here we examine the genetic basis of a spontaneous cuticle defect in silkworm, where larvae exhibit a bamboo-like body shape and decreased pigmentation. We performed linkage mapping and mutation screening to determine the gene product that affects body shape and coloration simultaneously. In these ...

Abstract The RNA-guided CRISPR/Cas9 system has been shown to be a powerful tool for genome editing in various organisms. A comprehensive toolbox for multiplex genome editing has been developed for the silkworm, Bombyx mori , a lepidopteran model insect of economic importance. However, as previous methods mainly relied on delivery of transient Cas9/guide RNA (gRNA), they could not be used in loss-of-function studies of essential genes. Here, we report a simple and versatile tissue-specific genome...

CRISPR–Cas9 genome editing is used to induce a DNA repair response and correct a disease-causing heterozygous mutation in human embryos with reduced mosaicism and preferential repair using the wild-type copy of the gene.

Abstract The insect neuropeptide prothoracicotropic hormone (PTTH) triggers the biosynthesis and release of the molting hormone ecdysone in the prothoracic gland (PG), thereby controlling the timing of molting and metamorphosis. Despite the well-documented physiological role of PTTH and its signaling pathway in the PG, it is not clear whether PTTH is an essential hormone for ecdysone biosynthesis and development. To address this question, we established and characterized a PTTH knockout line in ...

Abstract Forkhead box O (FOXO) functions as the terminal transcription factor of the insulin signaling pathway and regulates multiple physiological processes in many organisms, including lifespan in insects. However, how FOXO interacts with hormone signaling to modulate insect growth and development is largely unknown. Here, using the transgene-based CRISPR/Cas9 system, we generated and characterized mutants of the silkworm Bombyx mori FOXO (BmFOXO) to elucidate its physiological functions durin...

Abstract Olfaction plays an essential role in many important insect behaviors such as feeding and reproduction. To detect olfactory stimuli, an odorant receptor co-receptor (Orco) is required. In this study, we deleted the Orco gene in the Lepidopteran model insect, Bombyx mori , using a binary transgene-based clustered regulatory interspaced short palindromic repeats (CRISPR)/Cas9 system. We initially generated somatic mutations in two targeted sites, from which we obtained homozygous mutants w...
