DEFINITION

Classification: 435/410

PLANT CELL OR CELL LINE, PER SE (E.G., TRANSGENIC, MUTANT, ETC.); COMPOSITION THEREOF; PROCESS OF PROPAGATING, MAINTAINING, OR PRESERVING PLANT CELL OR CELL LINE; PROCESS OF ISOLATING OR SEPARATING A PLANT CELL OR CELL LINE; PROCESS OF REGENERATING PLANT CELLS INTO TISSUE, PLANT PART, OR PLANT, PER SE, WHERE NO GENOTYPIC CHANGE OCCURS; MEDIUM THEREFORE:

(under the class definition) Subject matter which includes plant cells or cell lines, per se which may be transgenic, mutant, or products of other processes for obtaining plant cells; compositions containing plant cells; processes of in vitro propagating, maintaining or preserving plant cells or cell lines; processes of isolating or separating plant cells; processes of regenerating plant cells into tissues, plant parts, or plants, per se, wherein no genotypic change occurs; and medium for propagation, maintenance, preservation, etc. of plant cells or cell lines.

(1) Note. Not included in this subclass, are processes wherein a product is synthesized by a biochemical transformation of matter; i.e., a transformation wherein the transforming agent is a plant cell culture or tissue or processes wherein the tissue is first cultured and then destroyed by subsequent extraction, for example to extract compound or composition from the tissue. Such subject matter is provided for in subclasses 41+ of this class.

SEE OR SEARCH THIS CLASS, SUBCLASS:

262+, for processes wherein a preexisting material or

compound present in a composition or material is contacted with an enzyme, plant cell, animal cell, etc. to isolate or recover the preexisting material which is chemically unchanged by the process.

317.1, for subcellular parts of microorganisms (bacteria, animal cell, plant cell, etc.).

440+, for processes of producing a stable heritable change in the genotype of a microorganism, an animal cell, or a plant cell by artificially inducing a structural change in a gene or by the incorporation of genetic material from an outside source. Processes of mutation which are processes directed to the production or selection of essentially random changes to the DNA of a cell without the incorporation of exogenous DNA are provided for in this area. Also included are processes in which the cellular matter of two or more fusing partners is combined producing a fused or hybrid cell.

SEE OR SEARCH CLASS 47, Plant Husbandry, for apparatus and processes used in treating the earth and its products and includes all inventions relating thereto that have not been especially provided for in other classes.

1.1, includes mushroom culture. Subclasses 59+ include processes for fostering growth beyond germination of plants in a soilless nutrient environment (water culture). Subclass 57.6 includes coated or impregnated seed not specifically provided for elsewhere. Subclass 58.1 includes miscellaneous processes for plant cultivation and propagation.

426, Food or Edible Material:Processes, Compositions, and Products, appropriate subclasses for products and processes of preservation and preparation of edible material, including earth products.

504, Plant Protecting and Regulating Compositions, for compositions for treating terrestrial or aquatic plants or their habitat with chemicals which affect the growth characteristics of the plants and processes of mere use of said compositions.

800, Multicellular Living Organisms and Unmodified Parts Thereof and Related Processes, for methods of plant breeding, methods of mutating plants, methods of producing plants using somatic cell fusion, methods of introducing nucleic acid into or rearrangement of genetic material within a plant, and for plants and plant parts, per se.
