Description

7.2kb per construct under the control of an Hsp70 promoter.

Expression of a 4.9kb EcoRI-HindIII per fragment fused to a 2.3kb HindIII-SalI per fragment (entire per coding sequence, 340bp of the first intron and 2.1kb DNA 3' to the site of transcription termination) is driven by a 450bp XbaI-EcoRI fragment of Hsp70 promoter (sequences necessary for heat inducible transcription).

Expression of a 6.8kb XbaI-EcoRI fragment of per (300bp of the first intron and the complete coding region) is driven by a 450bp XbaI-EcoRI fragment of an Hsp70 promoter.

Detailed Description
Statement
Reference

In wild-type males, 5 hours of courtship conditioning is insufficient to reduce courtship behaviour 5 days later. However, it is sufficient to cause such reduction in perhs.PEa males heat shocked before conditioning. In these heat shocked males there is no reduction in courtship behaviour during conditioning, suggesting that the effect is due to improved long term memory of courtship conditioning, rather than an effect on courtship behaviour itself.

After 7 days of light dark (LD) entrainment, when the mating activity is measured in these flies on the second day of dark dark (DD) cycling thee is no difference seen in mating activities between circadian time (CT) 12 and CT18. However, after heatshock the mating activity at CT12 is significantly lower than at CT18.

When reared at 18oC adults exhibit arrhythmic behaviour. When shifted to 29oC adult behaviour is rhythmic.

Shifting from 18 to 19oC at different stages of the life cycle demonstrates rhythmic adult behaviour can only be obtained if per expression is induced in the adult. The action of per after light:dark entrainment seems to be sufficient for activity rhythms to be exhibited in constant darkness.

Comments

perhs.PEa rescues the loss of long term memory in per01 males as assayed by reduction in mating activity in the presence of 5 days after conditioning for 7 hours as long as heat shock is given just before conditioning.
