Summary
Impatiens is the genus of
popular ornamental bedding plants. Ball Horticultural Co. has a
granted United States patent related to a method for the production of
transgenic Impatiens plants by transforming an Impatiens
tissue with Agrobacterium having either a vector with a selectable
marker gene and a foreign gene or two expression vectors where one of them has a
selectable marker gene and the other one a foreign gene.

Title - Production of transgenic Impatiens
Claim 1
A method for producing transgenic Impatiens plants, comprising the
steps of:
(a) introducing an expression vector into a plant tissue explant via
Agrobacterium to produce a transformed explant, wherein said expression
vector comprises a selectable marker gene and a second foreign gene, or
(a') introducing two expression vectors into said plant tissue explant via
Agrobacterium to produce a transformed explant, wherein one of said
expression vectors comprises a selectable marker gene, and wherein the second of
said expression vectors comprises a second foreign gene;
(b) culturing said
transformed explant on a selection medium;
(c) culturing said transformed
explant on regeneration medium; and
(d) recovering fertile transgenic
plants from said transgenic explants capable of transmitting said foreign gene
to progeny.
|
Claim 36
A fertile transgenic Impatiens plant having stably integrated in the
plant genome a foreign gene, wherein said transgenic Impatiens plant is capable
of transmitting said foreign gene to progeny.
|
Granted US 6121511 recites a method to produce transgenic
Impatiens plants by introducing into an Impatiens tissue
either one expression vector having a selectable marker and a second foreign
gene or two expression vectors where one of them contains a selectable marker
and the other one contains a second foreign gene. The introduction of one or two
vectors into the tissue is via Agrobacterium. The transformed tissue is
regenerated into fertile transgenic plants with the foreign gene stably
integrated in the genome. The progeny of these plants also contain the foreign
gene.

Title - Production of transgenic Impatiens
Claim 1
A method for producing transgenic Impatiens plants, comprising the
steps of:
(a) introducing an expression vector into an Impatiens plant tissue
explant to produce a transformed explant, wherein said expression vector
comprises a selectable marker gene and a second foreign gene and said plant
tissue explant is selected from the group consisting of Impatiens
shoot tips, Impatiens hypocotyl tips, and Impatiens node
regions, or
(a) introducing two expression vectors into said plant tissue
explant to produce a transformed explant, wherein one expression vector
comprises a selectable marker gene, and wherein the other expression vector
comprises a second foreign gene;
(b) culturing said transformed explant on
a selection medium;
(c) culturing said transformed explant on a
regeneration medium; and
(d) recovering fertile transgenic plants from said
transgenic explants capable of transmitting said second foreign gene to progeny.

This granted patent is a divisional of now granted
US 6121511 (see above).
Granted US 6528703 recites a method for producing transgenic
Impatiens plants that is not limited to
Agrobacterium-mediated transformation, and the Impatiens
plant tissue explant that can be used is limited to shoot tips, hypocotyl tips
and node regions.
