Did You Know...
...that one person who claimed to be the inventor of the television is Russian emigre Vladimir Zworykin? In 1929 David Sarnoff, founder of RCA, asked Zworykin what it would take to develop TV for commercial use. He said: a year and a half and $100,000. In reality, it took 20 years and $50 million! Before his death in 1982 at the age of 92, Zworykin said of his invention: "The technique is wonderful. It is beyond my expectations. But the programs! I would never let my children even come close to this thing."

| 5097025 | Plant promoters Five subdomains of the CaMV35S promoter are provided that cause tissue specific and/or developmentally regulated expression of chimeric genes in plants. These subdomains act as promoters for use in transformed plant cells, seeds and transgenic plants. Som... | 03/17/1992 |
| 5034322 | Chimeric genes suitable for expression in plant cells This invention relates to chimeric genes which are capable of being expressed in plant cells. Such genes contain (a) a promoter region derived in a gene which is expressed in plant cells, such as the nopaline synthase gene; (b) a coding or structural sequ... | 07/23/1991 |
| 4990607 | Alteration of gene expression in plants A transacting DNA binding factor is disclosed. The ASF-1 protein factor specifically binds to the sequence motif TGACG found upstream of the promoter in many plant genes. Co-expression of this protein factor augments the level of expression of the up-regu... | 02/05/1991 |
