A technology regarding the production, formulation and use of conditioned media and the factors included therein is disclosed. The conditioned media may be inoculated with animal cells, plant cells and any combination thereof. The inoculations may occur simultaneous or at different times. Cells retrieved from different areas of the animal and/or the plant may also be cultured together to form conditioned media and associated growth factors.

An apparatus (100) for use in culturing Sphagnum (106) is provided. The apparatus (100) comprises a culture vessel (102) for Sphagnum (106) and a culture medium (104) arranged in the culture vessel (102). The culture vessel (102) comprises an enclosed airspace (108) above the culture medium (104), and Sphagnum (106) arranged in the culture medium (104). The apparatus (100) further comprises means (110, 112) for supplying carbon dioxide into the enclosed airspace (108).

There are provided compositions and methods for transforming plants, preferably monocot, and even more preferably, sugarcane. The transformation methods involve infection of plant tissue with Agrobacterium, and co-cultivation using culture medium comprising high concentrations of gelling agent, with the result of inhibiting the exacerbated growth of the bacteria and increasing the transformation frequencies. The invention includes regenerating transformed plants, and the transformed plants themselves.

This invention relates to an agent for inducing a callus comprising a compound represented by Formula (I) or a hydrolysis product of an amide bond thereof:

##STR00001##

wherein Ar.sup.1 represents phenyl substituted with substituent or substituents selected from alkoxy and methylenedioxy; Ar.sup.2 represents phenyl substituted with halogen; R.sup.1 and R.sup.2 each represent hydrogen, alkyl, cyano, or carboxyl; R.sup.1 and R.sup.2 may together form oxo; R.sup.3 to R.sup.10 each represent hydrogen or methyl; and R.sup.3 and R.sup.4, R.sup.5 and R.sup.6, R.sup.7 and R.sup.8, and/or R.sup.9 and R.sup.10 may together form oxo; a method for inducing a callus and a method for plant transformation using such agent for inducing a callus.

The present invention provides medium compositions and methods for the regeneration of the whole plant from explants obtained from plants belonging to the Malvaceae family, particularly the Abelmoschus genus, more preferably Abelmoschus esculentus L, through somatic embryogenesis. The present invention also provides an efficient methodology for genetic transformation of plants belonging to the Malvaceae family through somatic embryogenesis in semisolid culture with the use of the Agrobacterium. The present invention is also related to a method for the development of virus-resistant transgenic plants belonging to the Malvaceae family.

The present disclosure provides an insulation layer composition and an insulation layer for a plant tissue culture. The insulation layer composition includes polyvinyl acetate emulsion resin, water, a gel forming agent and a hyaluronic acid diluent, in which the gel forming agent is a mixture of glycerin and polyglycerol acrylate. The insulation layer for the plant tissue culture includes the insulation layer composition.

Disclosed herein are methods of producing substantially pathogen-free plants of the genus Cannabis and pathogen-free plants and clones produced therefrom. One embodiment of the method comprises heating a progenitor plant of the genus Cannabis within a heating chamber resulting in a heat-treated plant, surface sterilizing a shoot segment of the heat-treated plant with a bleach solution, excising a meristematic tip of the shoot segment, and transferring the meristematic tip into a culturing plate comprising a supplemented Murashige and Skoog culture medium for further culturing. The supplemented Murashige and Skoog culture medium can comprise benzyladenine, naphthaleneacetic acid, gibberellic acid, or a combination thereof.
