142 Expression Patterns

• Primary Identifier: Expr12204
• Remark: Expression tested in C elegans

• Primary Identifier: Expr4693
• Remark: nsy-5 = T16H5.1.
• Pattern: A GFP reporter transgene with 5.8 kb of the nsy-5 promoter was expressed exclusively in sensory neurons and interneurons in the head and tail. The neurons that expressed nsy-5::GFP included AWC, ASH, AFD, ASI, ADL, ASK, BAG, AWB, and ADF (head sensory neurons); ADA, AIZ, RIC, AIY, and AIM (head interneurons); PHA and PHB (tail sensory neurons); and PVC and PVQ (tail interneurons). Expression began about halfway through embryogenesis, was strongest in late embryogenesis and the L1 larval stage, and faded thereafter. Adults maintained weak expression in several neurons, including ASH but not AWC.

• Primary Identifier: Expr4403
• Pattern: Strong and consistent expression was observed in a limited number of neurons in the head and tail and coelomocytes. Weaker and/or inconsistent expression of TTX-7::EGFP was detected in nerve cord motor neurons, intestine, and somatic gonad. The head neurons expressing ttx-7::EGFP include AFD and RIA neurons. Also expressed in ASH, ASE, ASJ, AWC, ADF, ADL, ASI, ASK, AWB, VNC motor neurons, etc.
• Subcellular Localization: TTX-7::EGFP was diffusely expressed in the cytoplasm and was not localized to any specific subcellular compartment.

• Primary Identifier: Expr4543
• Pattern: Expressed in ASEL/R, AWCL/R, AVKL/R, AFDL/R, few variable other neurons (weak).

• Primary Identifier: Expr4535
• Pattern: Expressed in AFDL/R, AIML/R.

• Primary Identifier: Expr4539
• Pattern: Expressed in AFDL/R.

• Primary Identifier: Expr15649

• Primary Identifier: Expr16432
• Pattern: We detected DMD-9::GFP expression in 10 head neurons of hermaphrodites at the L4 stage. High dmd-9 expression was detected in the BAG, AFD, AWCon, AWCoff, ASEL, and AWB neurons, with lower expression in ASER, and the ASGs. We also observed weak and inconsistent expression in other head neurons and transient weak expression in the tail of hermaphrodites and males at the L4 stage. No overt differences were observed in DMD-9::GFP expression in neurons of hermaphrodites and males. We also detected DMD-9::GFP expression in non-neuronal tissues. Transient DMD-9::GFP expression was observed in the uterine cells at specific sub-stages of the L4 stage. DMD-9 is not expressed from L4.0 to L4.3, with expression first detected in the early L4.4 stage, with the highest level during L4.4. before gradual loss by the L4.9 stage (Mok et al. 2015). DMD-9::GFP was not detected in adult uterine cells. We also detected DMD-9::GFP expression in sperm of hermaphrodites and males. In addition, we found that in a small proportion of L4 animals DMD-9::GFP shows asymmetric expression in the ASEs and AWCs neurons.

• Pattern: eat-4 is expressed in 78 of the 302 neurons of the adult hermaphrodite, which fall into 38 neuron classes (out of a total of 118 anatomically defined neuron classes in the hermaphrodite). Most of these neurons are either sensory- or interneurons. Only two motorneurons utilize glutamate; both are located in the pharynx.
