Abstract: The present inventors aimed to identify the gene responsible for the temperature-sensitive male sterility trait in “PL12” and to provide a method for producing conditional male sterile plants targeting the gene, and performed whole genome sequence analysis on “PL12” and the original variety thereof to compare the two. As a result, it was found that there was a deletion of about 150 kb in “PL12” chromosome 7. Then, as for this region, six types of partial deletion lines were produced by genome editing, and the presence or absence of the temperature-sensitive male sterility trait in each line was used as an index to successfully narrow the range, containing the responsible mutation, down to about 10 kb. Furthermore, as a result of creating a line with genome editing-disrupted functions of the two genes located in this region, the gene responsible for the temperature-sensitive male sterility trait was successfully identified.

Abstract: Developed and provided is a method of collecting a large amount of high-quality bagworm silk threads having no contaminant from bagworm nests in a convenient manner and at low cost. The habit of bagworms is utilized to allow a bagworm to build a nest using solvent-soluble substances or thermally meltable substances as nest materials, followed by dissolving or melting the nest materials to separate the nest material from the bagworm silk threads, whereby only pure bagworm silk threads constituting the bagworm nest can be obtained.

Abstract: According to the present invention, immortalized cells derived from porcine kidney macrophages are found to have high infection susceptibility to various African swlne fever virus strains. As a result, using the cells, it is possible to proliferate the virus and furthermore produce and detect the virus.

Abstract: An object of the present invention is to develop: a method of efficiently producing a long bagworm silk thread containing no contaminant while preventing a change in the spinning direction and the runaway of the bagworm from a rail, and alleviating a burden on the bagworm; and an apparatus for implementing the thread-producing method. Provided is an apparatus for producing a bagworm silk thread, having a movable rail having a width smaller than the maximum width between the right and left legs of a bagworm and configured to move in the longitudinal direction and to be able to hold with the legs of the bagworm; and a fixator configured to fix a bagworm, wherein the fixator is placed at a position such that the fixed bagworm can hold the movable rail.

Also developed and provided is a method of easily collecting eggs from a bagworm moth, an egg collection device for bagworm moths composed of a tubular container. A bagworm moth breeding method and egg collection method performed using the device are also described.

Abstract: An object of the present invention is to develop a method of producing pure and long bagworm silk threads having no contaminants, such as pieces of leaves and twigs, and a device for implementing the production method. Provided is a method of producing a long bagworm silk thread, the method having a spinning process of making a bagworm having its nest hang its legs on a rail and continuously spin a silk thread along the rail, wherein the rail has a width smaller than the maximum width between the left and right legs when the bagworm used spreads out its legs and wherein the rail is such that the bagworm can hang its legs on the rail, and a collection process of collecting a long silk thread from the rail after the spinning process.

Abstract: A method for producing an HSL protein with increased catalytic activity to oxidize a 4-HPPD inhibitor in a 2-oxoglutarate-dependent manner is disclosed. A method for producing a plant with increased resistance to a 4-HPPD inhibitor using the method for producing the HSL protein is also disclosed. It has been revealed that, by mutating position 140 to a basic amino acid in an HSL protein, the catalytic activity of the protein to oxidize a 4-HPPD inhibitor in a 2-oxoglutarate-dependent manner can be increased, and an activity of the protein to decompose the inhibitor can be increased.
