Title - Genetic modification of plants
Claim 1
A process for producing genetically modified Eucalyptus plant
material comprising one or more stably incorporated DNA sequences of interest,
which process comprises
(a) subjecting Eucalyptus cells or tissue to Agrobacterium
mediated transfer of the DNA sequence(s) of interest, inducing shoot formation
in transformed cells or tissue, and
(b) selecting
transformed material, the induction of shoot formation being carried out in the
presence of N-(2-chloro-4-pyridyl)-N'-phenylurea or another phenylurea.
|
Process for the production of genetically modified Eucalyptus with
stable DNA incorporated in its genome by transforming Eucalyptus
tissue or cells with Agrobacterium having gene(s) of interest. The
induction of shoot formation must have been carried out in presence of
phenylurea for the process to be covered by this claim.

Title - Process for transformation of mature trees of
Eucalyptus plants
Claim 1
A process for production of transgenic Eucalyptus plants from a
mature tree of Eucalyptus plant, comprising the steps of:
(1)
preparing a shoot tip explant from a mature tree of Eucalyptus
plant;
(2) inducing the shoot tip explant to form adventitious
shoots;
(3) pre-culturing the adventitious shoots to prepare infection in
an infection induction medium;
(4) infecting segments of explant cut out
from the pre-cultured adventitious shoots, with Agrobacterium
tumefaciens in an infection medium;
(5) rotary-culturing the segments
of the explant from the step (4) in a medium for sterilization containing
antibiotics so as to sterilize the Agrobacterium tumefaciens attached
to the segments of the explant, to form calli and to select transformed
calli;
(6) forming shoot primordia from the transformed calli;
(7)
regenerating transgenic plants from the transformed shoot primordia.
|
Granted AU 772053 recites a process to produce transgenic
Eucalyptus plants using A. tumefaciens to transform
"adventitious shoots" induced to form from "shoot tips" of a "mature"
Eucalyptus tree. Note that all the steps above must be used in order
for the claim to cover the process; additional steps may be added and the claim
would still cover the process if all the steps above are used.

Title - Methods for producing genetically modified plants,
genetically modified plants, plant materials and plant products produced thereby
Claim 1
A method for producing genetically modified plant material comprising:
(1) preparing an in vitro shoot culture of a target plant, the target plant
being of the Eucalyptus or Pinus species;
(2) maintaining
and growing the shoot culture until it has produced multiple modes and stem
segments;
(3) selecting and excising the stem segments from one or more
nodes of a shoot;
(4) transforming a stem segment by stably incorporating
a genetic contruct comprising a selection marker and a polynucleotide of
interest into the stem segment to form a putatively transformed stem
segment;
(5) exposing a putatively transformed stem segment to a selection
medium comprising a selection agent that permits survival of transformed stem
segments and is lethal to stem bud on the that were not successfully
transformed;
(6) selectively inducing the formation of an adventitious bud
on the putatively transformed stem segment to form a putatively transformed
adventitious bud;
(7) selectively regenerating the putatively transformed
adventitious bud by excising the putatively transformed adventitious bud and
exposing the putatively transformed adventitious bud to a selection medium
comprising a selection agent that permits survival of transformed adventitious
buds and is lethal to adventitious buds that were not successfully transformed
to identify a transformed adventitious bud; and
(8) elongating the
transformed adventitious bud to form a transformed shoot.
|
This patent expired due to non-payment of maintenance fees according to
USPTO.
Granted US 6255559 recites a method for transformation of
Eucalyptus or Pinus species based on introducing a desired
gene into an in vitro shoot culture and using excised stems with multiple nodes
grown from that culture as targets for transformation. Transgenic adventitious
buds are induced in a medium containing a selection agent and regenerated into
plants. The mode of transformation is not limited to that using A.
tumefaciens.

Title - Methods for producing genetically modified plants,
genetically modified plants, plant materials and plant products produced thereby
Claim 1
A method for producing genetically modified plant material of the
Eucalyptus or Pinus species, comprising:
(1) culturing nodal stem segments of a target plant selected from the
Eucalyptus and Pinus species;
(2) transforming the stem
segments with a genetic construct by incubating the nodal stem segments with an
Agrobacterium culture transformed with the genetic construct;
(3)
promoting regeneration of adventitious shoot buds from the transformed stem
segments;
(4) selecting transformed adventitious shoot buds; and
(5)
regenerating transformed plant material from the transformed adventitious shoot
buds.
