Evolution of color vision in pierid butterflies: blue opsin duplication, ommatidial heterogeneity and eye regionalization in Colias erate
This paper documents the molecular organization of the eye of the Eastern Pale Clouded Yellow butterfly, Colias erate (Pieridae). We cloned four cDNAs encoding visual pigment opsins, corresponding toExpand

Coexpression of three middle wavelength-absorbing visual pigments in sexually dimorphic photoreceptors of the butterfly Colias erate
The tiered ommatidia of the Eastern Pale Clouded yellow butterfly, Colias erate, contain nine photoreceptor cells, four of which contribute their rhabdomeral microvilli to the distal tier of theExpand

Peculiar behavior of distinct chromosomal DNA elements during and after development in the dicyemid mesozoan Dicyema japonicum
The dicyemid mesozoans are obligate parasites that inhabit the cephalopod renal appendage. Dicyemids have a simple body, consisting of approximately 30 cells: one long cylindrical axial cell containsExpand

Extreme Spectral Richness in the Eye of the Common Bluebottle Butterfly, Graphium sarpedon
Butterfly eyes are furnished with a variety of photoreceptors of different spectral sensitivities often in species-specific manner. We have conducted an extensive comparative study to address theExpand

Differentiation of somatic mitochondria and the structural changes in mtDNA during development of the dicyemid Dicyema japonicum (Mesozoa)
Dicyemids (Mesozoa) are extremely simple multicellular parasites found in the kidneys of cephalopods. Their mitochondria are known to contain single-gene minicircle DNAs. However, it is not known ifExpand

Eyes with basic dorsal and specific ventral regions in the glacial Apollo, Parnassius glacialis (Papilionidae)
SUMMARY Recent studies on butterflies have indicated that their colour vision system is almost species specific. To address the question of how this remarkable diversity evolved, we investigated theExpand

Rhabdom evolution in butterflies: insights from the uniquely tiered and heterogeneous ommatidia of the Glacial Apollo butterfly, Parnassius glacialis
The eye of the Glacial Apollo butterfly, Parnassius glacialis, a ‘living fossil’ species of the family Papilionidae, contains three types of spectrally heterogeneous ommatidia. Electron microscopyExpand

Rough eyes of the northeast-Asian wood white, Leptidea amurensis
SUMMARY The northeast-Asian wood white, Leptidea amurensis (Lepidoptera, Pieridae), belongs to the Dismorphiinae, a subfamily of the family Pieridae. We studied the structure of the compound eye inExpand

Opsin duplication and strange eye regionalization in the eye of Graphium sarpedon
In butterflies’ lineage, several gene duplications of opsin have occurred and many butterflies make good use of excess opsins to get a new type of photoreceptor.  To clarify opsin duplications andExpand
