Structural and functional reconstitution of thin filaments in the contractile apparatus of cardiac muscle.
The muscle contractile apparatus has a highly ordered liquid crystalline structure. The molecular mechanism underlying the formation of this apparatus remains, however, to be elucidated. SelectiveExpand

Female-specific wing degeneration caused by ecdysteroid in the Tussock Moth, Orgyia recens: Hormonal and developmental regulation of sexual dimorphism
Females of the tussock moth Orgyia recens have vestigial wings, whereas the males have normal wings. During early pupal development, female wings degenerate drastically compared with those of males.Expand

The thoracic anatomy of the male and female winter moth Nyssiodes lefuarius (Lepidoptera: Geometridae) and evolutionary changes in the thorax of moths and butterflies
The thoraces of males and flightless females of the geometrid winter moth Nyssiodes lefuarius are described, documented in detail, and compared. Morphological, functional, and evolutionary aspects ofExpand

The developmental process during metamorphosis that results in wing reduction in females of three species of wingless-legged bagworm moths, Taleporia trichopterella, Bacotia sakabei and Proutia sp.
There are several evolutionary grades of wing reduction in female bagworm moths of the family Psychidae. In this family, female adults of Taleporia trichopterella, Bacotia sakabei and Proutia sp.Expand

Female-specific wing degeneration is triggered by ecdysteroid in cultures of wing discs from the bagworm moth, Eumeta variegata (Insecta: Lepidoptera, Psychidae)
Female adults of the bagworm moth, Eumeta variegata, are completely wingless; by contrast, the male adults have functional wings. Sex-specific differences in the development of wing discs appear toExpand

Fine-tuned Bee-Flower Coevolutionary State Hidden within Multiple Pollination Interactions
Relationships between flowers and pollinators are generally considered cases of mutualism since both agents gain benefits. Fine-tuned adaptations are usually found in the form of strict one-to-oneExpand

Ecdysteroid-Induced Programmed Cell Death Is Essential for Sex-Specific Wing Degeneration of the Wingless-Female Winter Moth
The winter moth, Nyssiodes lefuarius, has a unique life history in that adults appear during early spring after a long pupal diapause from summer to winter. The moth exhibits striking sexualExpand

In vitro effects of juvenile hormone analog on wing disc morphogenesis under ecdysteroid treatment in the female-wingless bagworm moth Eumeta variegata (Insecta: Lepidoptera, Psychidae).
Female adults of the bagworm moth, Eumeta variegata, lack wings completely, whereas male adults of this species have functional wings. We previously found that ecdysteroid induces apoptotic events inExpand
