Although the reading frame of the neighbouring ATPsyn-d gene is unaffected in the "cdiU2" mutant chromosome, it remains possible that its function could be affected, thus it is unclear whether the lethality of the "cdiU2" mutant chromosome is due to an affect on cdi or ATPsyn-d.
"FBti0009052 == P{lacZ}cdi87" was stated as tentative. "FBti0003444 == P{FZ}cdi242" was stated as tentative.
