DEFINITION

Classification: 435/430

Involving regeneration or propagation into a plant or plant part:

(under subclass 420) Subject matter wherein the process is one in which the plant cell or tissue regenerates or propagates into a plant or plant part which is more mature or differentiated than the starting cell or tissue, e.g., growing a mature plant from meristematic tissue, culturing a root to induce formation of a cell mass which is cultured in a medium which results in a plantlet, etc.

(1) Note. Plant parts include seed, embryo, flower, leaf, differentiated tissue (i.e., specific organs), bud, meristem, shoot, root, tuber, fruit, stem, cutting, bulb, corm, rhizome, pollen, mycelium, spore, ascocarp, and sclerotia.
