atf-2::gfp expresses in the excretory duct cell, as well as other cells in the animal including the excretory pore cell and cells of the egg-laying and digestive systems (data not shown). atf-2::gfp expression initiates in the embryo and persists into larval and adult stages.
Expression of a transcriptional reporter for the p38-ATF-7-regulated immunity gene T24B8.5 is detectable most prominently in the intestine, the digestive system counterpart, and declines with age.
Asymmetric expression of imb-2 in AWCON was also observed in our initial assessment of the imb-2 expression pattern using imb-2 fosmid::GFP in which we fused GFP with the C terminus of IMB-2 by homologous recombination, that rescued imb-2(vy10) mutants.
