在果蝇中，变形(DFD)和性梳子减少(SCR)基因决定了最前面的同源异构体单位遵循的发育路径。利用原位杂交，我们已经监测了这两个基因转录本的空间分布。DFD RNA在副节段0和1中积聚，SCR RNA积聚在副节段2和3中呈动态变化。在附属器形成过程中，DFD和SCR的表达似乎由节段性向节段性转变。这两个基因都是在想象发育过程中转录的：DFD在眼睛触角盘的一部分；SCR在唇盘和前胸盘。此外，我们还在所有间胸间盘的上皮细胞中发现了SCR RNA。
In Drosophila, the Deformed (Dfd) and Sex combs reduced (Scr) genes determined the developmental pathways followed by the most anterior metameric units. Using in situ hybridization, we have monitored the spatial distributions of transcripts from these two genes. Dfd RNA accumulates in parasegments 0 and 1; Scr RNA accumulation shows a dynamic pattern spanning parasegments 2 and 3. The expression of Dfd and Scr seems to change from parasegmental to segmental during formation of the gnathal appendages. Both genes are transcribed during imaginal development: Dfd in a portion of the eye-antennal disc; Scr in the labial and prothoracic discs. In addition, we find Scr RNA in the adepithelial cells of all mesothoracic discs.
