Dyl functions in hair morphogenesis. (A) An SEM of an adult ptc-Gal4 UAS-dyl RNAi wing. The ptc domain includes the region above the vein shown in the image (marked by dyl kd). Note the hair polarity phenotype. (B) A high mag SEM of an adult ptc-Gal4 UAS-dyl wing. The arrowheads point to the hair “cups”. (C) A high mag SEM of an adult ptc-Gal4 UAS-dyl wing. The arrowhead points to a hair “cups”. The arrows point to thin and/or branched dyl kd hairs. (D) An SEM of phenotypically wild type hairs from outside of the ptc domain of the ptc-Gal4 UAS-dyl RNAi wing in (A). (E) A Rose diagram showing the distribution of hair orientation for Ore-R wings. The arrow shows the mean orientation. (F). A bright field micrograph of the phenotype associated with a dyl kd (ptc-Gal4 UAS-dyl RNAi). (G) An SEM of a dylMI02088/Df wing. Note the abnormal hair polarity. The larger arrow points to a thin hair, the smaller arrow to a split hair and the arrowheads to “cups” at the base of dyl mutant hairs. (H). A bright field micrograph of a dylMI02088/Df wing. Note the poor alignment of neighboring hairs. (I) An SEM of a ptc-Gal4 UAS-dyl wing. (J) A higher mag SEM of a ptc-Gal4 UAS-dyl wing where the small branches (arrows) and split (arrowheads) can be seen. (K). A Rose diagram showing the distribution of hair orientation for dylMI02088/Df wings. The arrow shows the mean orientation. Note how much broader the distribution is than in Ore-R.
