The invention relates to the grafting of perennial monocots such as bananas and oil palms. Processes for the production of such plants are disclosed herein.

The present invention provides a longitudinally split immature tiller separated from a rhizome (LSITR), a cluster of multiple in vitro shoots (CMIT), a cluster of stem segments containing shoot primordia (CSSSP) and an in vitro tiller of Miscanthus x giganteus (Giant Miscanthus), and their uses in propagating Miscanthus x giganteus (Giant Miscanthus).

A method for disinfecting explants of Kadsura coccinea stems with buds and a method for directly inducing rapid proliferation of sterile buds by using the explants of Kadsura coccinea stems with buds involve processes such as selection, treatment and disinfection of explants, primary culture, subculture proliferation culture. The problem of difficulty in tissue culture and primary culture of Kadsura coccinea stems is solved, and the advantages include low contamination rate of explants, high propagation rate and robust proliferation of axillary buds. This allows obtaining sterile axillary buds of Kadsura coccinea through tissue culture, and provides support for tissue culture, rapid propagation and factory seedling of Kadsura coccinea in the future.

The present disclosure describes novel methods for preparing leaf-derived plant cell suspension cultures. The cell suspension cultures produced by the methods provide a renewable and efficient source of protoplasts for high-throughput transformation and other uses. Applicants have surprisingly found that protoplasts can be obtained from the cell suspension cultures with inexpensive cell wall degrading enzymes and that the protoplasts provide increased transformation efficiencies relative to protoplasts from other sources.

The present invention relates to a method for conducting high-throughput and directed mutagenesis for sugarcane resistance to glyphosate by plasma. The method is as follows: sugarcane embryonic calli are irradiated by a plasma instrument under a sterile condition for mutagenesis, wherein the mutagenesis power is 140˜200 W, the discharging distance is 35˜45 mm, the mutagenesis time is 110˜140 s and the protective gas is nitrogen; buffering culture, moderate/high concentration of glyphosate stress screening, differentiation into seedlings, glyphosate stress screening of bottle seedlings and stress screening via spraying glyphosate on the leave surfaces of potted plants are conducted for the treated calli. The present invention has the advantages of safe operation, simplicity, practicability, high handling capacity, low contamination, and due to implementation of directed stress screening, high screening efficiency, decreased subsequent screening workload and visual identification of resistant mutant strains.

The present application relates to methods for the production of plant material suitable for the extraction and purification of saponins, through plantations of clone plants of defined chemotype, including ultrahigh density plantations of Quillaja saponaria Molina, and methods to increase the recovery of saponins by solid/liquid extraction of the harvested plant material.

The present invention relates to a method for producing a dimeric stilbene using a plant callus culture solution. More specifically, the present invention relates to a method for producing a dimeric stilbene using a plant callus culture solution and a composition for dimeric stilbene production, which contains a plant callus culture solution as an active ingredient.
