“…1 If X-ray induced recombination creates mitotic clones before a developmental compartment is specified, cells marked by one of the two mutations used to mark the twin clones can appear on both sides of the compartment boundary. This is similar to observations of bilateral and some mosaic lepidopteran gynandromorphs where cells in both anterior and posterior wing compartments are included within the same clone and thus marked with the same phenotype 29,30 .…”

Here we reply to the “Refutation” of Lawrence, Casal, de Cellis, and Morata, who critique our paper presenting evidence for an organizer and compartment boundary subdividing the widely recognized posterior wing compartment of butterflies and moths (Lepidoptera) and Drosophila , that we called the F-P boundary. Lawrence et al . present no data from the Lepidoptera and while the data that they present from Drosophila melanogaster mitotic clones are intriguing and may be informative with respect to the timing of the activity of the A-P and F-P organizers, considerable ambiguity remains regarding how their data should be interpreted with respect to the proposed wing compartment boundaries. Thus, contrary to their claims, Lawrence et al . have failed to falsify the F-P boundary hypothesis. Additional studies employing mitotic clones labeled with easily detectable markers that do not affect cytoskeletal organization or rates of cell division such as GFP and RFP clones produced by G-Trace or Twin Spot Generator (TSG) may further clarify the number of compartment boundaries in Drosophila wings. At the same time, because Drosophila wings are diminutive and highly modified compared to other insects, we also urge great caution in making generalizations about insect wing development based exclusively on studies in Drosophila .

“…Gynandromorphism has been observed in several insect orders including Lepidoptera, Hymenoptera, Coleoptera, Diptera, and Orthoptera, but its occurrence across orders is not even [ 1 ]. Several thousands have been reported in Lepidoptera in comparison with 90 in Hymenoptera; however, this fact could be due to easily recognizable sexual dimorphic features in the former order [ 2 ].…”

The present study was dedicated to investigating the anatomical organization of distinct neuropils within the two brain hemispheres of a gynandromorphic moth of the species Helicoverpa armigera. High quality confocal imaging of a synapsin immuno-stained preparation combined with three-dimensional reconstructions made it possible to identify several brain structures involved in processing odor input and to measure their volumes in the male and female hemispheres. Thus, in addition to reconstructing the antennal lobes, we also made digital models of the mushroom body calyces, the pedunculus, and the vertical and medial lobes. As previously reported, prominent sexual dimorphism was demonstrated in the antennal lobes via the identification of a male-specific macroglomerular complex (MGC) and a female-specific complex (Fc) in each of the two brain hemispheres of the gynandromorph. Additionally, sex-specific differences were found in volume differences for three other neuropil structures—the calyces, pedunculus, and vertical lobe. The putative purpose of larger volumes of three mushroom body neuropils in females as compared to males is discussed.

“…The phenotype under somatic mosaicism is contingent on multiple components, including the formative time at which the mutation occurs, the segments of the body that are affected, and the pathophysiological effects of the mutation [2][3][4][5]. Gynandromorphs, which are congenitally masculine on one side of the centerline and genetically feminine on the other, represent the best model [6].…”

A 57-year-old woman experienced an abnormal feeling on the left side of her neck and difficulty breathing 90 minutes after eating Chinese noodles. She had a history of removal of a left sphenoid ridge meningioma one year earlier. She had experienced rigidity of her left neck and peripheral cold sensation on her left side in winter since approximately 10 years of age. She had experienced peripheral swelling of her left side and lower back pain of unknown origin on her left side several times. She had suffered for oral allergy syndrome since she was young. She sometimes experienced a tingling sensation on her lips and an unpleasant feeling in her throat after eating some types of fruit. On arrival, 180 minutes after eating the noodles, she had clear consciousness and stable vital signs. She had left neck and chest swelling without color change. Her difficulty breathing subsided spontaneously. A blood analysis revealed an increased level of immunoglobulin E. Neck computed tomography (CT) with contrast medium and magnetic resonance imaging (MRI) revealed left-side-limited edema in the subcutaneous area and surrounding esophagus and bronchus. These radiological findings denied hemorrhaging or pseudoaneurysmal formation. She underwent observational admission. After her edema improved, she was discharged on the third hospital day. A followup examination one week later showed the complete resolution of the neck and chest edema. A blood allergen test did not reveal the cause of the edema. The mechanism underlying the asymmetric transient edema after eating in the present case may involve somatic mosaic.
