This topic captures responses to the question posed to the Newsgroup recently: "What are some seminal contributions to plant biology and to science in general coming first from Arabidopsis?" Comments and additions are welcome.

An LL-diaminopimelate aminotransferase defines a novel variant of the lysine biosynthesis pathway in plants. Tom Leustek An LL-diaminopimelate aminotransferase defines a novel variant of the lysine biosynthesis pathway in plants.
circadian clock components Kevin M. Folta To me, I think of circadian clock components that were relevant to the animal literature, that were found first in Arabidopsis. Even cry1 receptors are important in animals with a minor role in plants (at best).

an Arabidopsis-specific orphan gene that functions in regulating carbon allocation Ling Li My research discovered an Arabidopsis-specific orphan gene that functions in regulating carbon allocation-- the first research to discover a function of an orphan gene in plant metabolism. The gene name is Qua Quine Starch.
