The stress-inducing of salt and arid.
5. turns of GhNPC1b genes of embodiment create Resistance Strain of Cotton against material
One:The structure of pCAMBIA1300-GhNPC1b-EPSP plant expression vectors
When GhNPC1b overexpression structures are built, the cDNA nucleotide sequences of GhNPC1b are inserted into into plant expression vector
In pCAMBIA1300-EPSP, plasmid pCAMBIA1300-GhNPC1b-EPSP is obtained.After enzyme action identification is correct, plasmid is imported
In agrobacterium tumefaciens AGL1 or LBA4404, for Genetic Transformation in Higher Plants.Wherein plant expression vector pCAMBIA1300-EPSP is
Full synthetic EPSP genes (two ends add BamH I, KpnI restriction enzyme sites respectively) is linked to the multiple clone site of pCAMBIA1300
Upper acquisition.PCAMBIA1300 carriers in plant expression vector pCAMBIA1300-EPSP are CAMBIA Products,
GenBank number of registration AF134296;EPSP genes number of registration is AY573186.1.
Two:The acquisition of transgenic cotton plant
Cotton seeds soak 15min with the mercuric chloride of 70% ethanol immersion 1min, 0.1%, then with nothing Jing after sulphuric acid lint
Bacterium water washing 5 times.After sterilization, seed is put into and is covered with the aseptic bottle of three metafiltration paper, adds appropriate amounts of sterilized water, in 28 DEG C of incubators
Sprout.After 2~3 days, hypocotyl length is inserted into germination seed in MS solid mediums and continues culture to 1~2cm, and plant height 7~
It is used for converting during 10cm.
Will (plasmid pCAMBIA1300-GhNPC1b-EPSP carries herbicide resistance gene EPSP and purpose base with carrier
Because of GhNPC1b) agrobacterium tumefaciens (AGL1 or LBA4404) 28 DEG C in the YEP culture medium of additional antibiotic at concussion and cultivate,
Concussion speed is 110r/min, makes antibacterial be in exponential phase.Then it is centrifuged 10 minutes under 3000r/min, abandons supernatant.
Thalline is washed with 1/2MS improvement fluid mediums, is collected by centrifugation.Again by the thalline 1/2MS for adding 100mg/L acetosyringones
Improvement fluid medium suspends, and 5~20 times of dilution is used for converting.In conversion test, 1% surfactant Silwet is added
L-77 (Lehle Seeds, USA) or Tween80.
When kind of a skin comes off or comes off soon, remove kind of skin and a piece of cotyledon, expose seedling stem apex.If the existing lobule of shoot apex
Occur, then peelled off with tweezers.After gently scratching apical meristem, the cotton balls of Agrobacterium bacterium solution will be moistened with (by sterilized non-fat cotton
Prepare) seedling top is put into, cotton-wool is removed after continuing 24h, suck the residual bacterium solution of infection site with aseptic filter paper.Seedling is contaminated
When be placed in vacuum desiccator, be aided with 0.5 × 105The Negative pressure of Pa.The seedling contaminated in 21 DEG C or so light cultures 3 days,
Then flowerpot is transplanted into after cultivating 2~3 days under light.Flowerpot bottom is soil, and top is the thick Vermiculitums of 6~8cm, is poured every other day
1/2MS improves inorganic salt solution.
Three:Transformed plant is screened and field planting
After plant to be transformed grows 3 true leaves, 1.6~1.8 ‰ herbicide glyphosate (transgenic selectable marker genes are sprayed
For EPSP) aqueous solution, with unconverted plant as control.Fountain height falls drop with plant and is advisable.Unconverted plant 3 days after spraying
Stop growing, start within 7~10 days or so dead.Plant after conversion processing, the change of some individualities are similar to adjoining tree, separately
Some individualities then continued propagation, without significant change.Plant grew to for 4~5 leaf phases, was colonized to field.
Four:The identification and utilization of transfer-gen plant
The selfing of transfer-gen plant Post flowering or sisters' knot reality.Seed is sowed in land for growing field crops or greenhouse, in plant four leaf stage
Take blade and extract DNA, using round pcr detection progeny plant whether foreign gene-carrying GhNPC1b, and count exogenous gene and exist
Segregation ratio in filial generation.
As a result show, organize by transgene receptor of aseptic seedling shoot apical meristem, can effectively obtain transfer-gen plant.And
And, in partial transgenic strain offspring, exogenous gene mode of inheritance meets Mendel's law, and stablizes in passing on.Turn base
Because of homozygous line Jing field character determinations and resistant determination, select and keep receptor kind fundamental characteristics and resistance is significantly improved
Transgenic line, and improve for cotton variety.
The preferred embodiment of the present invention described in detail above.It should be appreciated that the ordinary skill of this area is without the need for wound
The property made work just can make many modifications and variations with design of the invention.Therefore, all technical staff in the art
Pass through the available technology of logical analysis, reasoning, or a limited experiment under this invention's idea on the basis of existing technology
Scheme, all should be in the protection domain being defined in the patent claims.
