英语翻译
strain vs.clone:
If the sequence was obtained from a cultured isolate,then a strain
identifier is required.(A strain identifier is not the same as a
species epithet.The proper species name of your bacterial isolate is
not required.) Strain identifiers distinguish specific cultures so a
historical continuity can be traced from the parent culture to any
subsequent subculture(s).
This is important when strains differ at an infraspecies level,or,
in some cases,when they have been misidentified and are consequently
reclassified in another species.The strain designation you provide
will serve to distinguish yours from other extant and future isolates
that might be obtained elsewhere.Your isolates do not need to be
deposited in a culture collection in order to have strain designations.
A strain may be designated in any manner:by the name of an individual
or locality,or by a string of numbers and/or letters.For example,
how do you distinguish this culture in your laboratory notebook?
Alternatively,if this sequence was obtained by direct PCR-amplification
and cloning of an environmental bulk DNA sample,then please provide the
name of the clone or laboratory identifier.
