WormMine: ExpressionPattern Expr597

• Pattern: Following hatching, 6 pharyngeal muscle cells stain becoming increasingly intense during larval and adult development. 6-7 neurons are stained in the ventral cord identified as DB motor neurons. Late larval and adult stages, staining of the set of DB and VB motor neurons in the ventral cord and their axonal processes along the ventral cord shows higher intensity of staining in late larval and adult stages. At L4, Pharyngeal muscles and the motor neurons show intense staining in L4 and adult stages. Fusion gene expressed in intestinal nuclei showing a gradient of expression, high staining in the posterior most intestinal nuclei in the tail region to a lower intensity of staining in the anterior intestinal nuclei. Intestinal staining decreases (L3-L4) and adult stages. Staining is detected in entire intestinal organ. Expression in neurons includes a set of DB and VB (19 cells) in the ventral nerve cord, a pair of posterior mechanosensory receptor neuron PLML and PLMR a single interneuron PVT in the pre-anal ganglion and a single neuron ALA in dorsal ganglion in the head.
• Primary Identifier: Expr597
• Remark: Reporter gene fusion type not specified. This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope). tba-2 in this article is referred as alpha-2 tubulin, while the same authors referred it as tba-2 in later publications such as cgc2176.
