Feature	source
Definition	identifies the biological source of the specified span of the sequence; this key is mandatory; more than one source key per sequence is allowed; every entry/record will have, as a minimum, either a single source key spanning the entire sequence or multiple source keys, which together, span the entire sequence.
Mandatory Qualifiers	/organism="text" /mol_type="genomic DNA", "genomic RNA", "mRNA", "tRNA", "rRNA", "other RNA", "other DNA", "transcribed RNA", "viral cRNA", "unassigned DNA", "unassigned RNA"
Optional Qualifiers	/bio_material="[<institution-code>:[<collection-code>:]]<material_id>" /cell_line="text" /cell_type="text" /chromosome="text" /citation=[number] /clone="text" /clone_lib="text" /collected_by="text" /collection_date="text" /country="<country_value>[:<region>][, <locality>]" /cultivar="text" /culture_collection="<institution-code>:[<collection-code>:]<culture_id>" /db_xref="<database>:<identifier>" /dev_stage="text" /ecotype="text" /environmental_sample /focus /frequency="text" /germline /haplotype="text" /host="text" /identified_by="text" /isolate="text" /isolation_source="text" /label=feature_label /lab_host="text" /lat_lon="text" /macronuclear /map="text" /mating_type="text" /note="text" /organelle=<organelle_value> /PCR_primers="[fwd_name: XXX, ]fwd_seq: xxxxx, [rev_name: YYY, ]rev_seq: yyyyy" /plasmid="text" /pop_variant="text" /proviral /rearranged /segment="text" /serotype="text" /serovar="text" /sex="text" /specimen_voucher="[<institution-code>:[<collection-code>:]]<specimen_id>" /strain="text" /sub_clone="text" /sub_species="text" /sub_strain="text" /tissue_lib="text" /tissue_type="text" /transgenic /variety="text"
Molecule Scope	any
Comments	transgenic sequences must have at least two source feature keys; in a transgenic sequence the source feature key describing the organism that is the recipient of the DNA must span the entire sequence; see Appendix IV /organelle for a list of <organelle_value>
