Fig. 1. Deficiencies significantly modified the bwk DA phenotype. DIC images of stage-14 egg chambers. (A) Canton S egg chamber exhibiting two long, tubular DAs (bracket). (B) bwk¹⁵¹/bwk⁸⁴⁸² egg chamber with shortened and broadened DAs (bracket). Note the remnant nurse-cell material caused by a defect in nurse-cellcytoplasmic transport (asterisk). (C) In(2L)pk78s/+; bwk^151/8482 egg chamber exhibiting suppression of the DA defect. The amount of remnant nurse-cell material is unchanged (asterisk). (D) Df(2R)Jp8/+; bwk^151/8482 egg chamber showing an enhanced bwk DA defect. The DA length is reduced and the shape of the appendage is altered. This deletion uncovers the gene shark.
