Isolation and characterization of new environmental bacteriophages are performed for (1) analyzing microbial evolution and ecology and (2) delivering biological therapy. The sampling of environmental bacteriophages appears, however, to be limited by the procedure (usually liquid enrichment culture) used to propagate them. An alternative, less competitive procedure is developed here for the purpose...
We have cloned and characterized the rat inducible nitric oxide synthase (iNOS) gene. It spans approx. 36kb and is divided into 27 exons and 26 introns. The distribution and length of exons are similar to those in the human iNOS gene. In the 5' flanking regulatory region of the rat iNOS gene, there are a number of putative transcription factor binding sites (>20), many of them probably indispensable...
Complete genomic DNA sequences of three homoeologous Waxy structural genes, located on the chromosomes 7A, 4A, and 7D in hexaploid wheat (Triticum aestivum L. cv. Chinese Spring), were separately determined and analyzed. Those structural genes in lengths from start to stop codon were 2781bp in Wx-7A, 2794bp in Wx-4A, and 2862bp in Wx-7D, each of which consisted of 11 exons and ten introns. They were...
