Morphology and gonad development of normal soldiers and reproductive soldiers of the termite Zootermopsis nevadensis nevadensis (Isoptera, Archotermopsidae)

Expression and function analyses of the hormone signaling genes during soldier differentiation of the termite Zootermopsis nevadensis

A New Apical Microtubule-associated Organelle in the Sternal Gland of Zootermopsis Nevadensis (hagen), Isoptera

The apical portion of the columnar cells of the sternal gland of the termite Zootermopsis nevadensis (Hagen) has been examined with the electron microscope. The cell surface abutting the cuticle is thrown into ridges upon which stand microvilli. Sections show a network of smooth membrane-bound cisternae penetrating the interior of the microvilli. At the bottom of the crevasses between the ridge...

The caste- and sex-specific DNA methylome of the termite Zootermopsis nevadensis

Epigenetic inheritance plays an important role in mediating alternative phenotype in highly social species. In order to gain a greater understanding of epigenetic effects in societies, we investigated DNA methylation in the termite Zootermopsis nevadensis. Termites are the most ancient social insects, and developmentally distinct from highly-studied, hymenopteran social insects. We used replica...

To DGC or not to DGC: oxygen guarding in the termite Zootermopsis nevadensis (Isoptera: Termopsidae).

The ability of some insects to engage in complex orchestrations of tracheal gas exchange has been well demonstrated, but its evolutionary origin remains obscure. According to a recently proposed hypothesis, insects may employ spiracular control of gas exchange to guard tissues against long-term oxidative damage by using the discontinuous gas-exchange cycle (DGC) to limit internal oxygen partial...

A genomic comparison of two termites with different social complexity

The termites evolved eusociality and complex societies before the ants, but have been studied much less. The recent publication of the first two termite genomes provides a unique comparative opportunity, particularly because the sequenced termites represent opposite ends of the social complexity spectrum. Zootermopsis nevadensis has simple colonies with totipotent workers that can develop into ...
