NEW PLANTS OR PROCESSES FOR OBTAINING THEM; PLANT REPRODUCTION BY TISSUE CULTURE TECHNIQUES
Definition statement
This subclass/group covers:

New plants (including multicellular algae, multicellular fungi and lichens).

Processes for modifying genotypes or phenotypes.

Plant reproduction by tissue culture techniques.

Methods or apparatus for producing changes in chromosome number.

References relevant to classification in this subclass
This subclass/group does not cover:
Unicellular algae
Fungal micro-organisms
Specific mutations prepared by genetic engineering on plant cell or plant tissues
Nucleic acid hybridization assays, detecting genotypes
Informative references
Attention is drawn to the following places, which may be of interest for search:
Influencing the growth of plants without producing new plants, non-chemically.
Influencing the growth of plants without producing new plants, chemically.
Special rules of classification within this subclass

A01H groups and subgroups are globally directed to tissue culture and classical breeding techniques and C12N 15/82 subgroups to transgenics. However the two are not mutually exclusive. For example traits which have been identified and used in transgenics may warrant classification in both areas, as may regeneration methods which are part of a transformation protocol.

Main groups A01H 5/00 through A01H 17/00 are only used for new, mainly non-transgenic, plants (usually varieties)

It is intended to create an indexing system for natural traits that mirror the transgenic phenotypes of the C12N 15/8241 range

Processes for modifying genotypes (A01H 4/00 takes precedence)
Definition statement
This subclass/group covers:

Tissue culture and classical breeding techniques (i.e non-transgenic) and apparatus for modifying genotypes e.g. artificial pollination, treatment with chemicals or with radiation in order to produce mutations.

Processes for modifying phenotypes, [N: e.g. symbyosis with bacteria] (A01H 4/00 takes precedence; influencing the growth of plants without producing new plants, non-chemically A01G 7/00, chemically A01N 25/00 to A01N 65/00)
Definition statement
This subclass/group covers:

Tissue culture and classical breeding techniques (i.e. non-transgenic) for modifying phenotypes e.g. treatment with chemicals.

Plant reproduction by tissue culture techniques; [N: Tissue culture techniques therefor]
Definition statement
This subclass/group covers:

Tissue culture techniques, apparatus, culture media for plant reproduction; methods for micropropagation; methods for regeneration to complete plants.
