• Primary Identifier: Expr725
• Remark: This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope). let-70 = ubc-2 --WS59.
• Reporter Gene: [ubc-2::lacZ] translational fusion. To make constructs pZMI.1 and pZMII.1, the lacZ coding region, a 3.3 kb BamHI-ApaI fragment from pPD16.43, was inserted in-frame into the second exon (BamHI-ApaI sites) of the ubc-2 genomic clone. PZMII.1 contained the 1.4 kb HindIII-BglII upstream sequence and the 2.6 kb 3' non-coding sequence. In pZMI1, a 6 kb BglII fragment preceding the initiation methionine codon and 2.6 kb of sequences downstream of the TAG stop codon was included in the construct to provide regulatory elements for expression.
• Pattern: UBC-beta-gal expression (from pZMI.1 and pZMII.1) was observed consistently in embryos, larvae and adults. Expression was detected in most cells in the embryos. In L1, L2, L3 and dauer larvae, most somatic tissues including neurons, pharynx, hypodermis and body muscle were intensely stained. In a small percentage of animals, intestinal staining were also stained. At the onset of L4, staining was restricted to neurons, pharynx and hypodermis. Staining was only seen in the nervous system in adults. An interesting feature of the expression patterns from pZMI.1 and II.1 is that, despite different tissue specificity in larval and adult stages, ubc-2-lacZ expression is seen constitutively in the nervous system at all post-embryonic stages. From L1 onwards, intense beta-gal staining was seen in ventral nerve cord, including P-cells and neurons, pharyngeal ganglia and retrovesicular ganglia.

• Primary Identifier: Expr726
• Remark: This information was extracted from published material (Archana Sharma-Oates, Andrew Mounsey and Ian A. Hope).
• Pattern: Staining of nervous system including the ventral nerve cord and pharyngeal ganglia. Staining was also seen in retrovesicular ganglia in adults. Staining was not only in the ventral nerve cord but also in the nerve bundles connecting the ventral and dorsal cords.

Definition	Name	Synonym	Primary Identifier
ganglion lies beside the nerve ring in the head, just anterior of the retrovesicular ganglion. It contains about 20 interneuron and motorneuron cell bodies that all send their neuronal processes into the ring. The cell bodies are divided into two groups by the intrusion of the excretory duct and canal. The cells are bounded by a basal lamina which physically separates them from the lateral ganglion even though they are adjacent to one another.	ventral ganglion	ventral ganglia	WBbt:0005298
