| identification of a novel cys2/his2-type zinc-finger protein as a component of a spermine-signaling pathway in tobacco. | in a previous work, we identified a cys(2)/his(2)-type zinc-finger transcription repressor, (zft1), that functions in a spermine-mediated signal transduction pathway in tobacco plants. database search disclosed the presence of another cys(2)/his(2)-type zinc-finger protein zfp1 (accession number aac06243) in tobacco plants. in this work, we characterized zfp1 and investigated whether this protein is also involved in a spm-signaling pathway. this factor showed the highest identity to petunia zpt2 ... | 2007 | 16882456 |
| toward a quarter century of pathogen-derived resistance and practical approaches to plant virus disease control. | the concept of pathogen-derived resistance (pdr) describes the use of genetic elements from a pathogen's own genome to confer resistance in an otherwise susceptible host via genetic engineering [j. theor. biol. 113 (1985) 395]. illustrated with the bacteriophage qbeta in escherichia coli, this strategy was conceived as a broadly applicable approach to engineer resistance against pathogens. for plant viruses, the concept of pdr was validated with the creation of tobacco plants expressing the coat ... | 2010 | 20109666 |
| resistance to tobamoviruses in transgenic tobacco plants expressing the coat protein gene of pepper mild mottle virus (korean isolate). | red pepper, one of the most important vegetable crops in korea, is severely affected by viral diseases causing 20-50% reduction in product yield. a pepper strain of tobacco mosaic virus (tmv-p) is the most common virus in red pepper. to study the molecular structure of the tmv-p virus, we generated cdna clones of the viral genome. partial sequencing of a few cdna clones revealed that tmv-p shares a 98% identity at the nucleotide level with the spanish isolate of pepper mild mottle virus (pmmv-s) ... | 1997 | 9264016 |
