Description

The P1\loxP cassette containing the w+mW.hs marker gene has been excised. The resulting allele contains a 200bp deletion in the yar promoter region (which removes two of the three yar transcription start sites).

      Detailed Description
      Statement
      Reference

      Homozygous females show a significant decrease in the level of total nighttime sleep. The average length of each nighttime sleep bout is reduced compared to controls, and coincides with an increase in the number of sleep episodes.

      Homozygous females do not increase total daytime sleep or the duration of daytime sleep bouts following sleep deprivation (in contrast to control flies).
