WormMine: ExpressionPattern Expr14654

• Pattern: The male-specific neuronal expression of lin-29a is not observed in male-specific neurons but is, interestingly, entirely restricted to sex-shared neurons (i.e. neurons that are generated in both sexes). Intriguingly, most of these neurons had not been previously reported to show sexually dimorphic gene expression patterns or functions. Specifically, 21 out of 116 sex-shared neuron classes express lin-29a, including seven sensory neuron classes in the head and tail (AWA, ASG, ASJ, ASK, ADF, PHB, PLM), seven interneuron classes (AVA, RIA, AIM, AVG, RIF, PVC, PVN), a few head and tail motor neurons (SAB, PDA, PDB) and most of the sex-shared ventral nerve cord motor neurons (dorsal and ventral A, B and D-type and AS neurons). Expression of lin-29a in all these neurons in the male nervous system is precisely temporally controlled; it is first observed in the early L4 stage and persists throughout adulthood.

Neuron class of thirteen motoneurons, with cell bodies in the ventral cord, which innervate ventral muscles. Each cell has an anteriorly directed process emanating from its cell body.	VD neuron		WBbt:0005303
Neuron class of six motoneurons, with cell bodies in the ventral cord, which innervate dorsal muscles. Each cell has a short, posteriorly directed and a longer, anteriorly directed process emanating from its cell body. The anterior process has a branch, which leaves the ventral cord as a commissure and runs round to the dorsal cord.	DD neuron		WBbt:0005270
