Phenotypic Description (Red Book; Lindsley and Zimm 1992)

l(1)1Bb

Homozygous clones in eyes display swelling and vacuolization of pigment cells (alleles designated MM2 and TE10). Deletion for l(1)1Bb enhances central-nervous-system and eye effects of ASC deficiencies (Jimenez and Campos-Ortega, 1987, J. Neurogenet. 4: 179-200; Gonzalez, Romani, Cubas, Modolell, and Campuzano, 1989, EMBO J. 8: 3553-62).

Expression Data

Testis-specificity index

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Additional comments

l(1)1Bb¹⁹ complements ebo⁶⁷⁸, indicating that l(1)1Bb and ebo are not members of the same complementation group.

(Poeck, 2014.3.8)

The l(1)1Bb complementation group was previously merged with the ebo gene in FlyBase, based on information in FBrf0125093 (which provided molecular map information for the region including ebo and information about changes in the restriction enzyme map of this region in l(1)1Bb mutants). However, FBrf0224496 shows that the l(1)1Bb¹⁹ allele complements ebo mutant alleles. Thus l(1)1Bb and ebo have been split back out into separate gene records in FlyBase.
