Cloning and sequence analysis of the gbpC gene encoding a novel glucan-binding protein of Streptococcus mutans
We have isolated dextran-aggregation-negative mutants of Streptococcus mutans following random mutagenesis with plasmid pVA891 clone banks. A chromosomal region responsible for this phenotype was…
Progress of lignification mediated by intercellular transportation of monolignols during tracheary element differentiation of isolated Zinnia mesophyll cells.
Results indicated that lignification on TEs progresses by supply of monolignols from not only TEs themselves but also surrounding xylem parenchyma-like cells through medium in vitro.

The gene, designated cnm, is identified as being involved in the agglutination of strain Z1 following random mutagenesis, and the amino acid sequence of the deduced Cnm protein exhibited high similarity to those of collagen-binding adhesins from staphylococci and other organisms.

Results indicate that diapause hormone, along with four other neuropeptides, is generated from a common precursor polyprotein that is encoded by a single mRNA transcribed in neurosecretory cells of SG.
Benzodiazepine receptor agonists modulate thymocyte apoptosis through reduction of the mitochondrial transmembrane potential.
The results suggest that the immunomodulating effect of benzodiazepines is in part due to the modulation of thymocyte apoptosis associated with the collapse of delta psi(m).
Neurosecretory cells expressing the gene for common precursor for diapause hormone and pheromone biosynthesis-activating neuropeptide in the suboesophageal ganglion of the silkworm, Bombyx mori.
A similar staining profile was observed in the SG cells at the larval, pupal, and adult stages, indicating that the DHP gene is expressed in the same set of cells throughout the postembryonic development.

Embryonic diapause and sex pheromone biosynthesis in the silkworm, Bombyx mori, are, respectively, induced by diapause hormone (DH) and pheromone biosynthesis activating neuropeptide (PBAN), which…
Xylitol-induced elevated expression of the gbpC gene in a population of Streptococcus mutans cells.
It is found that cells repeatedly cultured in the presence of xylitol evolved into those exhibiting an elevated dextran-dependent aggregation phenotype, found to result from expression of the gbpC gene, which was previously reported to be expressed only under certain stress conditions.
Isolation, characterization and sequence analysis of the scrK gene encoding fructokinase of Streptococcus mutans.
A gene encoding an ATP-dependent fructokinase from Streptococcus mutans GS-5 was identified within a 2 kb DNA fragment immediately downstream from the scrA gene, and Insertional inactivation of this gene in S. mutans markedly decreased both fructureokinase and mannokinase activities.
