Regeneration of multiple shoots via callus induction and organogenesis was achieved in mulberry (Morus bombycis). Pre-soaked internodal explants in 4.4–8.9 μM benzyladenine (BA) formed callus on Linsmaier and Skoog's medium containing 2,4-dichlorophenoxyacetic acid (9.05 μM), α-naphthaleneacetic acid (2.85 μM) and BA (2.2 μM). Explants soaked for 48 to 72 h(More)
Hyphae of Phyllactinia corylea produce two kinds of special branches on the host surface: adhesion bodies which serve as fungal attachment and stomatopodia which enter the leaf through stomata. Conidial germination on host and non-host surfaces was examined with a scanning electron microscope to explain the stimuli responsible for development of the special(More)
The mature conidia of Nomuraea rileyi (Farlow) germinate on the larval integument of Bombyx mori within 24 h and penetrate the cuticle within 36 h after inoculation at 24.0 ± 1.0 °C temperature and 80.0 ± 5.0% relative humidity. The penetrating hyphae multiply by budding and septa formation in the hemocoel, and the larva succumbs to the infection 6–7 days(More)
Injection of live Escherichia coli into larvae of the silkworm, Bombyx mori, induces antibacterial activity in the hemolymph. The major induced antibacterial activity was purified in two steps by CM-Sephadex C-50 and Sephadex G-100 column chromatography. After trypsin treatment, the purified antibacterial protein lost its activity and the antibacterial(More)
p67, a cellular glycoprotein, protects eIF2alpha from phosphorylation by inhibitory kinases such as double-stranded RNA dependent eIF2 kinase, PKR, and heme-controlled repressor and thus promotes protein synthesis in mammalian cells. To investigate whether p67 is essential for the survival of mammalian cells, the basal level of p67 was lowered from rat(More)
