Physical map of the region of chromosome III deleted by the deficiencysDf127 and not covered by the duplication sDp8. The heavy horizontal line represents the chromosome. Dotted lines above the chromosome indicate sequenced cosmids that are not available as transgenic strains. All other cosmids represented above the chromosome are available as part of the transgenic library. Shaded boxes indicate cosmids used to rescue essential genes in this study. Gene names are written underneath the cosmids to which they have been correlated. An inverted V beneath the chromosome line indicates the primer sites used to determine the left end point of sDf127. A − or + under the inverted V indicates that the primer site is deleted or not deleted, respectively. The approximate region deleted by the deficiencysDf127 is shown as a single line below the chromosome. Regions of uncertainty are represented by a broken line. The approximate region covered by the left end of sDp8 is shown by a broken double line below the chromosome.
