WormMine: ExpressionPattern Expr1359

• Pattern: Strong expression of gfp in embryos starting from the midgastrula stage. About a dozen nuclei expressed vab-15::gfp in midgastrula. Before and at the comma stage, numerous nuclei in all cell layers expressed vab-15. Embryos approaching the 2-fold stage had strong GFP fluorescence in ectodermal cells, including hypodermal cells and neuroblasts. vab-15 was expressed strongly in the set of 12 P cells from before hatching and during the L1 stage. In L2 and early L3 animals vab-15 was also expressed in seam cells and ventral cord motor neurons. Five unidentified cells in the head and four cells in the tail (PHBL/R and PVCL/R) expressed vab-15 throughout larval development. These cells were the only ones expressing the fusion in L4 larvae and adults. The head was almost devoid of vab-15 expression.
• Primary Identifier: Expr1359
• Remark: Reporter gene fusion type not specified.
• Subcellular Localization: vab-15 expression was nuclear at all stages.
