*o:g

I've been looking through the Pokorny list checking relationships
between long vowels and aspirate stops (part of a weird idea I have,
I'll tell you all about it some time). It turns out that long vowels
followed by unaspirated stops are pretty rare. For example, the only
word where o: is followed by g is *o:g, "to plant fruit." How
widespread is this root? It seems to appear in Latin and Russian as
ag-. I haven't found any obvious cognates in German, Icelandic,
Danish, Old English, or Greek (though it's certainly possible that
I've simply missed them). Modern English has borrowed ag- words from
Latin, so those don't count. It seems possible that Russian may have
also borrowed from Latin. Oddly enough my Pokorny list is pretty old,
and the newer lists on the Internet don't seem to have this root.
Could *o:g be unique to Latin?
