Figure 1. Expression Analysis of Candidate Cilia-Related Genes Identifies New Genes Expressed Exclusively in Ciliated Cells. Shown are whole-worm GFP and GFP/DIC merged images of transgenic animals expressing the indicated transcriptional gfp reporter. Expression is restricted to ciliated cells such as the amphid neurons (bracket), the labial-quadrant neurons (asterisk), and the phasmid-tail neurons (arrowhead). Note that for some markers (e.g., C54G7.4 and K07G5.3), the weak signals along the midbody are due to the nonspecific autofluorescence of gut granules.
