Brain, imaginal disc and blood cell neoplastic phenotype.
Lethality occurs during larval and pupal stages. Brain is smaller than wild type with abnormal shape. Discs are smaller than wild type with abnormal folding. Both discs and brain can exceed normal size at the end of larval life. Lymph gland retains lobular structure.
This allele was listed in the BDGP database as a lethal or sterile line during the period 1994-1999, but was discarded from the gene disruption project prior to the summary publication (FBrf0111489). Reasons for excluding lines from the collection described in FBrf0111489 include presence of more than one P insertion on the mutant chromosome, separation of lethality (or sterility) from the location of the insertion, and loss of lethality (or sterility) from the stock. Further information is available from http://www.fruitfly.org/bfd/ and from Dr. Spradling (spradling@mail1.ciwemb.edu).
The P{lacW}SmD3k15401 insertion appears to affect only SmD3 function and not Oda function (despite being within an Oda intron), since the lethality of P{lacW}SmD3k15401 homozygotes is fully rescued by the P{SmD3.+t2.3} construct which contains the complete SmD3 gene. Complements: OdaEP2104.
P-element excision demonstrates the insertion to be the cause of lethality.
