| downstream promoter sequence of an indian isolate of rice tungro bacilliform virus alters tissue-specific expression in host rice and acts differentially in heterologous system. | an indian isolate of rice tungro bacilliform virus from west bengal (rtbv-wb) showed significant nucleotide differences in its putative promoter region when compared with a previously characterized isolate from philippines. the transcription start site of rtbv-wb was mapped followed by assessing the activity and tissue-specificity of the full-length (fl) promoter (-231 to +645) and several of its upstream and downstream deletions by studying the expression of beta-glucuronidase (gus) reporter ge ... | 2007 | 17721744 |
