GO Vs Traits

Hi Pankaj, Jun Jian & others

This wrestling with affiliating 'things' with biological process vs traits
is philosophically & biologically interesting & pragmatically important.
>From the Systematics perspective (be that plant or animal systematics) the
concept of the term 'trait' can be alternatively described as a
distinguishing quality or characteristic - clearly a relatively generic
concept. In systematics the term trait is synonymous with the term
'Character' (and the various phenotypes of a trait are similarly referred to
as character states - just f.y.i.). Implicit in the term trait can be a
range of biotic- & abiotic-related phenomena e.g. biological processes (some
being responses to abiotic/environmental factors). Why am I thinking aloud
like this with you? Well, Pankaj raised the point about "the contradiction
between the Molecular biologist/Biochemist and the plant breeder/Geneticist,
on how he percieves the response. Whether as a trait or as a Bilogical
process ??" I suggest that this perceptual difference is going to remain
with us so am left wondering about how we will provide ontologies that are
biologically accurate & appropriate for the molecular etc. biologist as well
as being useful to a user of generic trait terms e.g. plant
breeder/geneticist. Photoperiod sensitivity is clearly a trait to a
geneticist (with a range of taxon-specific phenotypes) while at the same
time it is clearly based on an underlying biological process. The same
argument applies to 'Elongation'. It is likely that a breeder or geneticist
may not recognize a trait 'buried' within a biological process ontology. So,
I'm wondering if any thought has been given by the GO folk to the possible
inclusion of XML metatags within the ontologies so that ontology browsers
will be able to locate trait-related terms within the ontologies. The
purpose of this approach being to maintain the integrity of the ontologies,
w.r.t. the organizing principles, but at the same time provide embedded tags
to the generic labels which, for example, breeders & geneticists would
probably be more familiar with. This approach could overcome the need to
resolve the conflict between ascribing something to biological process vs a
trait - the trait info. would be embedded, via the metatags, in the
biologically sound relevant ontology.

Enjoy a thoughtful & fun weekend!
