3.0kb wild-type genomic fragment containing Idh3b. Contains the entire A isoform plus 198bp of upstream sequence.
The lethality of Idh3b1/Df(3R)Exel6188, Idh3b2/Df(3R)Exel6188 and Idh3b3/Df(3R)Exel6188 transheterozygous mutants is rescued by combination with a single copy of Idh3b+t3.0 as viable adults are recovered and the abnormal persistence of larval salivary gland characteristic for Idh3b mutants is not observed in the Idh3b2/Df(3R)Exel6188; Idh3b+t3.0 rescue pupae.
