The invention provides a method for the production of soybean embryogenic callus and somatic embryos. The invention further provides methods of transforming explants that includes generating somatic embryo tissue. The transgenic somatic embryos produced can be used for regenerating stable transgenic plants.

The present invention relates to a medium composition for production of botulinum toxin and, more particularly, to a medium composition for culture of Clostridium sp. capable of producing botulinum toxin. The medium composition of the present invention comprises at least one plant-derived peptone selected from the group consisting of a garden pea hydrolysate, a cotton seed hydrolysate and a wheat gluten hydrolysate. When the medium according to the present invention, which contains plant-derived peptones and minerals, is used for culture of Clostridium botulinum, the growth rate of the bacterium in the medium is about 1.5-2 times higher than that in the medium that is in current use. In addition, when botulinum toxin is produced by culturing the bacterium in the medium, infection with transmissible spongiform encephalopathy (TSE) or the like can be prevented by blocking introduction of animal-derived components.

The present invention relates to a method of producing Ingenol, Ingenol esters and/or Tiglian-3-one derivatives, the method comprising the steps of: (a) culturing plant cells obtained from a plant selected from the family Euphorbiaceae in a nutrient medium in a suspension cell culture, wherein the cells produce Ingenol, one or more Ingenol esters and/or one or more Tiglian-3-one derivatives; and (b) recovering the Ingenol, the one or more Ingenol esters and/or the one or more Tiglian-3-one derivatives produced in (a). The present invention further relates to a plant suspension cell culture, wherein the cells are obtained from a plant selected from the family Euphorbiaceae, and wherein the plant cells produce Ingenol and/or one or more Ingenol ester and/or one or more Tiglian-3-one derivatives. The present invention further relates to a plant cell biomass comprising plant cells obtained from the suspension cell culture of the invention, and comprising Ingenol and/or one or more Ingenol esters and/or one or more Tiglian-3-one derivatives. Also, the present invention relates to cryopreserved cells of the plant suspension cell culture of the invention as well as to a method of producing Ingenol, Ingenol esters and/or Tiglian-3-one derivatives based on these cryopreserved cells.

The present invention relates to excision of explant material comprising meristematic tissue from cotton seeds. Methods for tissue preparation, storage, transformation, and selection or identification of transformed plants are disclosed, as are transformable meristem tissues and plants produced by such methods, and apparati for tissue preparation.

The present invention relates to methods and compositions for transforming soybean, corn, cotton, or canola explants using spectinomycin as a selective agent for transformation of the explants. The method may further comprise treatment of the explants with cytokinin during the transformation and regeneration process.

According to the present disclosure, there is provided a method for culturing cells into which a reprogramming factor is introduced including culturing cells into which a reprogramming factor is introduced; and recovering all cells into which the reprogramming factor is introduced and seeding and passaging at least part of the recovered cells in a medium. In addition, there is provided a method for culturing cells into which a reprogramming factor is introduced, including culturing cells into which a reprogramming factor is introduced; and inducing somatic cells different from pluripotent stem cells without passaging the cells into which the reprogramming factor is introduced.

The present invention relates to methods and compositions for transforming soybean, corn, cotton, or canola explants using spectinomycin as a selective agent for transformation of the explants. The method may further comprise treatment of the explants with cytokinin during the transformation and regeneration process.

A bioreactor liquid agitation device may include a rack which may be movably coupled to a frame. Preferably, a motivator which may be configured to motivate the rack in a movement circuit. A rack may comprise one or more sets of rails. Each rail may comprise a channel which may be formed by two opposing retaining walls which may be coupled to and separated by a central wall. A set of two rails, with each rail having its channel facing the other rail, may be configured to support one or more bioreactors by receiving opposing portions of a vessel coupler of each bioreactor in the two channels. An arrester may be coupled to the rack(s), and the arrestor may block the vessel couplers from exiting an end of the channels so that the vessel couplers may only enter and exit the channels from an opposing end of the channels.

The invention points to a process of production of anthocyanins from Aristotelia chilensis callus cultures, which is divided into 2 essential steps: the first is the obtaining of biomass in an A. chilensis callus culture, the second step consists of eliciting the production of anthocyanins in the culture, to obtain the desired product. In this way, callus cultivation is presented as a new alternative to provide a nutritional additive rich in anthocyanins appropriate for the food industry, or any other application that requires anthocyanins that does not depend on seasonality or environmental factors.

The present invention relates to excision of explant material comprising meristematic tissue from seeds, and storage of such material prior to subsequent use in plant tissue culture and genetic transformation. Methods for tissue preparation, storage, and transformation are disclosed, as is transformable meristem tissue produced by such methods, and apparati for tissue preparation.
