Carried in plasmid "Ubx-B", expressed in haploid cell line 1182-4 and the effect of trx and Pc on the Ubx promoter is studied to determine if trx is involved in promoter activation and Pc-dependent repression can be reproduced. Competitive interactions between trx and Pc are also examined in haploid cell line 1182-4 using Ecol\lacZUbx.bxd14.5.
Presence of trx is able to maintain long term Ubx expression.
