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.

The present invention relates to a plant regeneration medium composition and a plant regeneration method using same. More specifically, the present invention relates to a plant regeneration medium composition using a medium composition containing Shungite as an active ingredient to increase the rates of shoot organogenesis and root organogenesis, thereby shortening the time required for organogenesis using a plant explant and improving the efficiency of ontogeny, and to a plant regeneration method using same.

Provided is a plant having at least one of genetic characteristics (A)-(E) below. (A) Alleles in which the base at the position corresponding to position 40 of SEQ ID:1 is C are homozygous or heterozygous. (B) Alleles in which the base at the position corresponding to position 21 of SEQ ID:2 is T are homozygous or heterozygous. (C) Alleles in which the base at the position corresponding to position 28 of SEQ ID:3 is T are homozygous or heterozygous. (D) Alleles in which the base at the position corresponding to position 59 of SEQ ID:4 is C are homozygous or heterozygous. (E) Alleles in which the base at the position corresponding to position 64 of SEQ ID:5 is T are homozygous or heterozygous.

The present disclosure provides a method for obtaining adventitious tetraploid buds of Blumea balsamifera, comprising the following steps: selecting a root segment of diploid B. balsamifera as an explant, culturing the root segment in a chromosome doubling inducing medium supplemented with 0.025-0.1 mg/L 1-naphthaleneacetic acid (NAA), 1.0-2.0 mg/L 6-benzylaminopurine (6-BA), and 90-150 mg/L colchicine, inducing explant cells, and simultaneously doubling chromosomes and differentiating the adventitious buds. The present disclosure fills the blank of using a root of B. balsamifera as the explant and increases effective explant sources during the propagation, proliferation and biotechnological breeding of B. balsamifera. More importantly, root cells of the B. balsamifera are directly differentiated into adventitious buds while chromosomes are doubled, and a callus formation process is not needed, so that the technical links are simplified and the variation of regeneration buds and the generation of chimeras are reduced.

The invention provides seed and plants of tomato hybrid DR2379TH and the parent lines thereof. The invention thus relates to the plants, seeds and tissue cultures of tomato hybrid DR2379TH and the parent lines thereof, and to methods for producing a tomato plant produced by crossing such plants with themselves or with another tomato plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of such plants, including the fruit and gametes of such plants.

The present invention relates to OsNF-YA5 gene from Oryza sativa for increasing nitrogen availability of plant and uses thereof. Since the OsNF-YA5 gene of the present invention can increase or improve nitrogen availability of a plant, it can be advantageously used for developing a plant which enables lesser consumption of nitrogen fertilizer while maintaining the same plant yield, i.e., an environment friendly plant with lower production cost.

The present invention relates to a Lactuca sativa seed designated 41-607 RZ. The present invention also relates to a Lactuca sativa plant produced by growing the 41-607 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 41-607 RZ.
