The present invention is directed generally to eukaryotic cells comprising single-celled organisms that are introduced into the eukaryotic cell through human intervention and which transfer to daughter cells of the eukaryotic cell, and methods of introducing such single-celled organisms into eukaryotic cells. The invention provides single-celled organisms that introduce a phenotype to eukaryotic cells that is maintained in daughter cells. The invention additionally provides eukaryotic cells containing magnetic bacteria. The invention further provides eukaryotic cells engineered with single-celled organisms to allow for multimodal observation of the eukaryotic cells. Each imaging method (or modality) allows the visualization of different aspects of anatomy and physiology, and combining these allows the imager to learn more about the subject being imaged.

The present disclosure relates to increasing oil content in plants through manipulating expression of proteins, namely At5g16550 proteins. At5g16550 proteins are lipid droplet proteins. Plants having reduced expression of At5g16550 proteins demonstrate cytoplasmic lipid droplets (LDs) that are increased in size, resulting in greater overall oil content in the plant cells.

This invention relates to recombinant Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) arrays and recombinant nucleic acid constructs encoding Type I-E CASCADE complexes as well as plasmids, retroviruses and bacteriophage comprising the same.

The present disclosure relates to a method for constructing a trehalose polyenzyme complex in vitro by mediation of an artificial scaffold protein, which mainly comprises the following steps: constructing a recombinant bacterium WB800n-ScafCCR for self-assembled scaffold protein module; constructing a recombinant bacterium WB800n-P43-phoD-treY-Ccdoc for self-assembled catalytic module; constructing a recombinant bacterium WB800n-P43-phoD-treZ-Ctdoc for self-assembled catalytic module; constructing a recombinant bacterium WB800n-P43-phoD-cgt-Rfdoc for self-assembled catalytic module; secretorily expressing the recombinant bacteria and self-assembling in vitro to obtain a recombinant trehalose multi-enzyme complex. The trehalose multi-enzyme complex constructed by the method of the present disclosure has a higher catalytic efficiency in preparing trehalose than that of mixed free enzymes, and the method can be used for production of high quality trehalose after immobilization with cellulose microspheres.

The present invention provides a modified strain of the bacterium Lactococcus lactis obtainable by a method that comprises a step of fusion of two protoplasts from two Lactococcus lactis parental strains which, compared to the wild type strain of Lactococcus lactis from which they derive, show: (a) an increased ability to produce acetoin and/or 2,3-butanediol (2,3-BDO), and (b) a decreased ability to produce lactic acid, when cultured under aerobic conditions, and wherein the modified strain of Lactococcus lactis has an increased ability to produce 2,3-BDO of at least 20 times the amount produced by the wild type strain, an increased ability to produce acetoin of at least 20 times the amount produced by the wild type strain and a decreased ability to produce lactic acid of at least 10 times the amount produced by the wild type strain, when cultured under aerobic conditions. Also provided are methods to produce acetoin and 2,3-BDO.

This disclosure provides methods for performing quantitative-trait loci (QTL) analysis in bacteria. The methods of the instant disclosure utilize multiple rounds of protoplast fusion-induced genomic recombination to break genetic linkages in bacterial genomes. The methods of the instant disclosure allow determining which genetic elements (QTL) are associated with phenotypic al features.

A system for expressing a chloramphenicol split protein is disclosed. Uses thereof are also disclosed.
