Parish Priests and Parishioners, purple-flowered petunia plants genetically modified by the introduction of DNA containing a chalcone synthase coding sequence under the control of the strong CaMV 35S promoter and the 3′ end from the nopaline synthase gene of Agrobacterium. The selectable marker gene consisting of the coding sequen

Church, State and Society, 1760–1850a large number of transgenic plants containing sense nd antisense transgenes have been generated for various purposes. First, antisense and sense genes have been introduced into commercial crops and ornamental plant varieties to suppress the expression of resident genes with the aim of modifying or

Ukrainian Greek Catholics, Past and Presentalso in plants with suppressed levels of transgene expression (reviewed by J. 1991; K. and M. 1993; M. and M. 1993). In many silencing cases, the transgene and homologous host genes are coordinately suppressed in the plants, a phenomenon called co-suppression (N. et al. 1990). Although the underlyin

The Family Man and Writer in the 1930s M.C. recognized that certain isolates of the element either cycled between inactive and active phases during development or underwent an inactivation event of longer duration and sufficient stability to be heritable, but which was nonetheless occasionally reversed (M.C. 1957, 1958). In subsequent s

,Churchill’s India, 1942 to 1943,f repeat-induced point mutation (RIP; reviewed in S. 1990b) and quelling (P. and R. 1992; R. and M. 1992) may account for the rarity of repetitive sequences. RIP is a dramatic example of gene inactivation: duplicated gene-sized DNA sequences are efficiently detected and peppered with transition muta
