DEFINITION

Classification: 435/257.2

Transformants:

(under subclass 257.1) Subject matter involving an algae which is 1) a product of recombination or transformation with (a) a vector, or (b) a foreign or exogenous gene, or 2) a product of homologous recombination if it is directed rather than spontaneous, or 3) a product of fused cell formation.

(1) Note. Fused cells are cells of which the cellular matter of two or more individual cells is combined producing a singlecell which initially contains the genes of all the combined cells.

(2) Note. Excluded from this subclass are products of unidentified or noninduced mutations, and products of natural, spontaneous, or arbitrary recombination events. These are not considered genetically modified for this subclass and therefor will be classified as unmodified algae (subclasses 257.1, and 257.3 through 257.6).

SEE OR SEARCH THIS CLASS, SUBCLASS:

440+, for processes of mutation or genetic engineering wherein the genetic mate-rial of a microorganism (e.g. an algae) is altered.
