In sporulating cultures of Bacillus thuringiensis subsp. yunnanensis HD977, two cell types are observed: cells forming only spores and cells forming only crystals. Curing analysis suggested that the crystal proteins are plasmid encoded. Through plasmid transfer experiments, it was established that a 103-MDa plasmid is involved in the crystal production. Conjugal transfer of this plasmid to Cry-...

To investigate the genetic diversity and phylogenetic relationships of Salvia miltiorrhiza and related species, we analyzed the nuclear ribosomal DNA internal transcribed spacer (ITS) region for 7 accessions of Salvia miltiorrhiza and another 23 samples from other taxa within the genus Salvia by maximum parsimony and Bayesian inference analyses. Th ere were 257 variation sites amounting to 40.8...
