1) l(2)35Be = CG4140. The evidence for this is: (i) CPTI-000130 is inserted in CG4140 and does not complement the lethality of l(2)35Be4 (see www.flyprot.org) (ii) by deletion mapping l(2)35Be and l(2)35Bc map to the dyn-p25 - l(2)35Bd interval; l(2)35Be maps to the left of l(2)35Bc. There are 3 genes in this interval - CG4140, NC2beta and CG4103. Candidates for l(2)35Be are therefore CG4140 and NC2beta. (iii) Two l(2)35Be alleles (2 and 4) have point mutations in CG4140, but not in NC2beta. 2) l(2)35Bc = CG4103. The evidence for this is: (i) by deletion mapping l(2)35Be and l(2)35Bc map to the dyn-p25 - l(2)35Bd interval; l(2)35Be maps to the left of l(2)35Bc. There are 3 genes in this interval - CG4140, NC2beta and CG4103. Candidates for l(2)35Bc are therefore NC2beta and CG4103. (ii) Two l(2)35Bc alleles (4 and 6) have premature stop codons in CG4103, but not in NC2beta.
