pKK41 is expressed in the same groups of cells as the elt-5
translational reporter (pKK52), but the relative expression levels are different. Whereas the elt-5
reporter is strongly expressed in both seam cells and the nervous system during the comma through pretzel stages, the elt-6
reporter is strongly expressed only in the nervous system. Only weak expression of the elt-6
reporter is apparent in seam cells and in the AB and MS descendants during embryogenesis, but the seam expression becomes stronger during larval development. Strong expression of the elt-6
reporter in the nervous system continues throughout larval development.
