Eleutherococcus senticosus/embryogenic cells KCTC 0504BP are subcultured to homogeneous sizes of somatic embryos in MS liquid medium. The somatic embryos are cultured in a bioreactor equipped with an airlift to produce the seedlings or plantlets. The Eleutherococcus senticosus/seedlings or plantlets cultured in the bioreactors can be used for extracting components therefrom. The seedlings or plantlets can be eaten and powdered for use in health beverages or tea.Type: GrantFiled: May 24, 2000Date of Patent: July 16, 2002Assignee: Microplants Co., Ltd.Inventor: JaeWhune Kim

Patent number: 6392121Abstract: A gene amplification system based on plant viral genetic elements dramatically increases foreign protein production in plants. A safer and more economical production system for vaccines and antibodies in recombinant plants grown using agricultural practice is described. The high-level expression system uses the replicative process of a plant mastrevirus, exemplified by bean yellow dwarf virus (BeYDV). The expression system is preferably inducible to avoid interference with plant growth and development. Developmental cues, such as fruit ripening, are employed to trigger expression of the foreign protein using a tissue-specific promoter. A single, stably integrated expression cassette for foreign protein is replicated extrachromosomally in ripening fruit, forming hundreds of transcriptionally competent copies. Preferred plant hosts include tomato as a model system and soybean for production of large quantities of protein at high total protein levels.Type: GrantFiled: October 7, 1999Date of Patent: May 21, 2002Assignee: Boyce Thompson Institute for Plant ResearchInventors: Hugh S. Mason, Kenneth E. Palmer, Kathleen L. Hefferon, Tsafrir S. Mor, Charles Arntzen

Patent number: RE39114Abstract: Introducing sucrose phosphorylase activity into plants by transformation with a gene for the enzyme increases the rate of sucrose hydrolysis, leading to increased starch, oil, and/protein levels. Sucrose phosphorylase genes from Streptococcus mutans and Leuconostoc mesenteroides have been found particularly advantageous for use in the present invention. Surprisingly, in potatoes transformed to express these genes in tubers, reduced bruise discoloration susceptibility and increased uniformity of starch deposition throughout the tuber are achieved.Type: GrantFiled: May 22, 2003Date of Patent: May 30, 2006Assignee: Monsanto Technology LLCInventors: Gerard Francis Barry, Jan Willem de Weerd, Ganesh Murthy Kishore, Marcia Lee Weldon
