Abstract: Murine leukemia virus (MLV) and lentivirus vectors have been used previously to deliver genes to hematopoietic stem cells (HSCs) in human gene therapy trials. However, these vectors integrate randomly into the host genome, leading to disruption or inactivation of vital host genes. The present invention discloses a novel lentiviral vector system that overcomes this problem by integrating into a host genome in a site-specific manner.

Abstract: Chemically inducible promoters are described that may be used to transform plants, including tobacco and lettuce, with genes which are easily regulatable by adding the plants or plant cells to a medium containing an inducer of the promoter or by removing the plants or plant cells from such medium. The promoters described are ones that are inducible by a glucocorticoid or estrogen which is not endogenous to plants. Such promoters may be used with a variety of genes such as ipt, CKI1, or knotted1, to induce shoot formation in the presence of an appropriate inducer. The promoters may be used with genes which induce somatic embryos such as Lec1 or SERK to prepare somatic embryos which can be grown into seedlings and then into plants. The promoter may also be used with antibiotic or herbicide resistance genes which are then regulatable by the presence or absence of inducer rather than being constitutive. Other examples of genes which may be placed under the control of the inducible promoter are also presented.
