The present invention provides a soybean genetic transformation method using PMI as selectable gene, and relates to the technical field of genetic engineering. In the soybean genetic transformation method of the present invention, using the PMI gene as a selectable marker, soybean explants are infected by recombinant Agrobacterium with the PMI gene and a target gene, followed by co-culture; without recovery culture, the co-cultured explants are directly selected by a selective medium supplemented with mannose, where transformed explants with the PMI gene grow normally under selection pressure of mannose, while non-transformed explant growth is inhibited, thereby selecting successfully transformed positive plants; after shoot elongation and transplantation of the positive plants obtained, genetically transformed soybean plants are obtained successfully. Using the soybean genetic transformation method as provided by the present invention, soybeans can be genetically transformed by PMI genes derived from any species, achieving safe soybean genetic transformation.

The disclosure provides an aseptic sowing and raising seedling method for distant hybridization seeds of Phalaenopsis and Rhynchostylis retusa, which takes Phalaenopsis as female parent and Rhynchostylis retusa as male parent to obtain hybridization fruit pods by artificial pollination, the fruit pods are pretreated, and the seeds are aseptically sowed, germinated, protocorm proliferated and differentiated, strong seedlings rooted, acclimatized and transplanted to obtain distant hybridization offspring groups. The disclosure has the advantages of high seed germination rate, large seedling number, short seedling time and good seedling quality, which solves the problems that the seeds of Phalaenopsis distant hybridization process are difficult to succeed due to affinity, and are extremely difficult to germinate and raise seedlings under natural conditions. Therefore, a large number of seedlings can be obtained in a short period by aseptic sowing and artificial propagation, which lays a foundation for breeding excellent varieties of Phalaenopsis distant hybridization.

A Stevia extract made from leaves of the Stevia rebaudiana plant is described. The extract has desired levels of steviol glycosides and is useful in food, beverage, and other consumable products.

The present invention is directed to a transgenic plant and a method for producing the same. In particular, the present invention is directed to a transgenic plant or a plant cell in which a nucleic acid molecule encoding an m.sup.6A demethylase is introduced, wherein said m.sup.6A demethylase has the following two domains: i) N-terminal domain (NTD) having the function of AlkB oxidation demethylase; and ii) C-terminal domain (CTD). The present invention is also directed to a method for producing said plant, comprising introducing a nucleic acid molecule encoding an m.sup.6A demethylase into a regenerable plant cell, and regenerating a transgenic plant from the regenerable plant cell.

A method of producing a stably transformed corn plant in a single container is demonstrated. This method allows for the automation of the transformation process and reduces labor, material, and ergonomic costs associated with traditional plant tissue culture systems.
