Note:

The number of spots coding tryptopyrokinin, SMYamide, Inotocin, Periviscerokinin and Leucokinin in transcriptome SRAs prepared from different body parts of D. truncata show that tryptopyrokinin is abundantly expressed in the thorax, but not in the suboesophageal ganglion where SMYamide and inotocin are produced by major neuroendocrine cells. Note that the absence of periviscerokinin spots in the abdomen transcriptome SRA does not equate the absence of periviscerokinin expression in the abdomen. The relative mass of the ventral nerve cord in the abdomen of a female is very small and hence CNS specific mRNAs are easily missed. Total refers to the total number of spots in each SRA. PeriVK, periviscerokinin; SMYa, SMYamide; TryptoPK, tryptopyrokinin.
