A method of producing a transgenic silkworm that spins bagworm silks and producing a large quantity of bagworm silks by transgenic technology is developed and provided. A gene encoding a modified bagworm Fib H and a transgenic silkworm in which the gene is introduced, wherein the gene is obtained by cloning a gene fragment encoding a bagworm Fib H-like polypeptide comprising a partial amino acid sequence of bagworm Fib H, and fusing the gene fragment to a gene fragment encoding silkworm-derived Fib H, are provided.

An automated oyster maturation system including a containment assembly rotatably disposed within a housing. The containment assembly includes a spiral construction that includes compartments that are in communication with one another, walls that define the compartments, and ramps. Openings disposed in the walls and ramps increase in size from the outer diameter to the inner diameter of the spiral construction so that, with every complete rotation of the containment assembly, every oyster will tumble further into the spiral construction and ascend from its original compartment into the adjacent inner compartment where opening size is larger than in the original compartment such that only oysters which have grown sufficiently can remain in the adjacent inner compartment while oysters that have not grown sufficiently yet will fall through the openings of the adjacent inner compartment into the original compartment.

Provided is an aquacultured crustacean having improved umami, uses thereof, and a method for producing the same. The crustacean does not burrow in sand, contain glycine and alanine, and has 2400 mg or more of free amino acids per 100 g of abdominal muscle. The content of glycine is 550 mg or more per 100 g of abdominal muscle, and the content of alanine is 140 mg or more per 100 g of abdominal muscle.

A TPR1 gene related to a low-temperature tolerance of Pomacea, coding protein and application of the gene is disclosed. The disclosure belongs to the field of biotechnology. The present disclosure is rapid, effective and reproducible, and is an important complement to the TPR1 gene family. Pomacea is an important invasive organism, the disclosure is helpful for developing novel biological pesticide, and the low-temperature tolerance of the organism is reduced by blocking the expression of TPR1 gene in Pomacea, so as to control the further northward invasion of Pomacea. Meanwhile, by interfering with the expression of TPR1 gene, the hatching rate of Pomacea eggs can be significantly reduced, and the hatching period of eggs can be prolonged, thereby reducing the harm of Pomacea invasion.

The present invention relates to a modified Slmyc2 gene, which may comprise at least one modification as compared to the wild type sequence of SEQ ID No. 5, which modification leads to the reduction or absence of SlMYC2 protein activity, wherein the modified Slmyc2 gene is capable of conferring an aberrant glandular hair phenotype to a Solanum lycopersicum plant. The modification may be suitably selected from a modification that decreases the mRNA level of the Slmyc2 gene, a modification that decreases the level of the SlMYC2 protein and/or a modification that decreases the activity of the SlMYC2 protein, as compared to the wild type Slmyc2 gene of SEQ ID No. 5.

Disclosed are an attenuation system and the use thereof for attenuating plasmodia, specifically the use of an EF1g gene for attenuating plasmodia. The attenuation system regulates the expression or degradation of the EF1g gene by using a regulatory system, thereby controlling the growth of plasmodia and achieving the attenuation of plasmodia.

The present invention provides a method for storing insect larvae by means of a storage means. The insect larvae are stored in a cooling medium, e.g. water, in the storage means. The amount of water in the larvae-water mixture in the storage means is controlled to be between 30% and 80%. The content of the storage means is maintained at a temperature below 15 C. The content of the storage means is agitated using agitating means included in the storage means.

The invention discloses a method for improving immunity in shrimps, by administering an extract of cocoa rind to a shrimp body to improve immunity of the shrimp body. The extract of cocoa rind is obtained by extracting a dried sample of cocoa rind by an aqueous ethanol solution with a concentration of ethanol being 90-98%. The dried sample of cocoa rind has a water content of 2-5%.

The present invention provides systems and non-invasive methods for gender selection of eukaryotic organisms More specifically, the invention applies the CRISPR-Cas system as well as any derivatives and fusion proteins thereof for creation of transgenic eukaryotic organisms and for selecting the desired gender of the resulting progeny.
