We previously showed that a 383 bp (-274 to approximately +109) promoter of a pollen-specific gene, GBAN215-6, had a property of a late gene in pollen development in transgenic tobacco plants. It drove GUS gene expression from uninucleate microspores to pollen tube growth of trinucleated cells. To

Positive-negative selection using hygromycin phosphotransferase (hpt) and diphtheria toxin A-fragment (DT-A) as positive and negative selection markers, respectively, allows enrichment of cells harboring target genes modified via gene targeting (GT). We have developed a successful GT system

The anther (tapetum)-specific gene BcA9 was isolated from Chinese cabbage, Brassica campestris L. ssp. pekinensis cv. Jangwon, using the Arabidopsis tapetum-specific A9 gene as a probe. The DNA and amino acid sequences of the coding region of the BcA9 gene showed high homology with A9 genes from

Pierisin-1 is a potent apoptosis-inducing protein derived from the cabbage butterfly, Pieris rapae. It has been shown that pierisin-1 has an A small middle dotB structure-function organization like cholera or diphtheria toxin, where the "A" domain (N-terminal) exhibits ADP-ribosyltransferase

The S-locus glycoprotein gene of Brassica is derived from the genetic locus that controls the self-incompatibility response and the specific recognition between pollen and stigma. The promoter of this gene was used to direct expression of the diphtheria toxin A chain gene and the Escherichia coli

Various Japanese foodstuffs are directly-acting mutagens in Salmonella typhimurium TA100 after nitrite treatment. Such mutagen precursors include tyramine and beta-carboline derivatives, isolated from soya sauce, and indole-3-acetonitrile, 4-methoxyindole-3-acetonitrile and
