OP50: lac promoter

Periodically, people ask what the genotype of OP50 is, but this is
apparently lost in the mists of time....
(http://www.bio.net/hypermail/CELEGANS/9710/0019.html)

I have a less general question. Does anyone know whether in OP50 a
plasmid-encoded gene under the control of the lac promoter would be
expressed constitutively; i.e. does OP50 have the lacIQ gene or not?

Thanks in advance
