Definitions
- the present invention relates to a method for genet transformation of tissues from monocotyledonous plants.
- the invention also comprises tissues from monocotyledons transformed by means of the method according to the inve tion.
- Transformed plants are formed by inserting, by means of genetic engineering, genetic material into individual cells (protoplasts) or into an intact tissue. Since the Agrobacterium system has considerable limitations when applied to cereals, transformation systems based on direct gene transfer have been developed for cereals (Paszkowski et al 1986). The drawback of these gene transfer methods, e.g. electroporation and microinjection, is the difficulty of the receptor cells to divide and form intact fertile plants. However, by using standard methods for direct gene transfer to protoplasts from embryogenic suspension cul ⁇ tures, it has been possible to regenerate fertile trans- genic rice plants (Potrykus 1990).
- the invention relates to a method for genetic trans ⁇ formation of tissues from a monocotyledonous plant, in which method genetic material is inserted into a vector i a bacterium, whereupon the bacterium is co-cultivated wit a microspore culture of the plant to be transformed.
- the method preferably is applied to cereals, espe ⁇ cially to barley.
- tis- sues are meant seeds, embryos, proembryos, microspores, pollen etc.
- the invention also comprises genetically transformed tissues from a monocotyledonous plant which has been transformed by insertion of genetic material into a vecto in a bacterium which is subsequently co-cultivated with a microspore culture of the monocotyledonous plant.
- the inventive method for transforming tissue organs from monocotyledons, especially cereals is based on tech niques for cultivating isolated microspores.
- microspores cultivate in vitro have the capability of dividing and differentiat ing to embryos.
- the development has reached a stage when the surrounding wall bursts, and a proembryo is released.
- the smaller number of cells neede for regeneration the better is the cultivation system suited for gene transfer.
- a 6-day-old proembryo consists of some hundred cells, it is still very small as compared with a fully developed embryo. A transformation at this stage means good prospects of obtaining embryos which largely consist of transformed tissue.
- the invention is based on co-cultivation of microspores of the plant to be transformed with bacteria cells which contain a vector having the genetic material which is desired to be inserted in the host plant.
- a bacterium which has appeared to function well in the field of the invention is Agrobacterium, especially Agrobacterium tume aciens.
- the transformation process can be divided into four 5 steps, i.e.
- Fig. 1 shows the vector pPCV 002
- Fig. 2 shows the vector pCVHPT GUS
- Fig. 3 shows Southern blot I with the HPT fragment as the probe.
- Fig. 4 shows Southern blot II 500 bp vector sequence as the probe
- Fig. 5 shows Southern blot III with the HPT fragment as 25 the probe, and
- Fig. 6 is a photo of a regenerated fertile transgenic bar ⁇ ley plant. The invention is described in more detail in the Exam ple below which is not limiting. 30 EXAMPLE
- Isolated microspores from barley are used as starting material for the experiment, since a well functioning 35 method for cultivating isolated barley microspores and for regenerating plants therefrom is available.
- Agrobac ⁇ terium tumefaciens was selected as a suitable bacterium for insertion of the genetic material.
- the Agrobacterium tumefaciens used includes the vec ⁇ tor pCVHPT GUS (Fig. 2) which results in hygromycin resis tance.
- the vector pCVHPT GUS is based on another vector, pPCV 002 (Fig. 1) (Walden et al 1990).
- pCVHPT GUS a gene for hygromycin resistance was inserted, viz. HPT 2030 bp, at the EcoRI-Sall-site in the polylinker molecule from pPCV 002.
- the reporter gene for beta glucuronidase (GUS) (Jefferson et al 1986) replaced the NPT II gene in pCVHPT GUS between pNOS and pAccs from pPCV 002.
- Barley microspores at a late single nucleus to early double nuclei stage are isolated from ear which has been refrigerated as +4°C for 4 weeks.
- the microspores are cul tivated in 7 cm Petri dishes in the dark at 25°C in N6 medium (Chu 1978) mixed with 1.75 mg/1 2,4-D 0.25 mg/1 kinetin 63 mg/1 maltose.
- the culture medium is replaced by a new N6 medium mixed with 0.5 % MES
- the material After adding the bacteria, the material is placed in the dark where it is first agitated at 30-40 rpm for 20 min. and is then allowed to stand for 3 days. Selection and Regeneration of Transgenic Barley Plants After the period of 3 days, the culture medium is replaced by selective N6 medium mixed with 10 mg/1 hygromycin 200 mg/1 Claforan.
- Claforan The function of Claforan is to stop the growth of the excess of Agrobacterium cells, while the hygromycin is added for selection of transformed tissue only, to which the hygromycin gene has been transferred.
- the embryo material is transferred to a regeneration medium consist ⁇ ing of J-25-8-medium (Jensen 1983) mixed with 0.5 mg/1 IAA 1 mg/1 kinetin
- barley plants About 8 weeks after the initial microspore isolation, barley plants have been regenerated. They are transferred to soil and placed in a greenhouse.
- This consists of a 500 bp vec ⁇ tor sequence from pCVHPT GUS which is not integrated between the T-DNA boundary sequences and which thus canno be transferred to the barley genome.
- This additional con ⁇ trol is performed in order to determine that the initial positive signals do not derive from surviving Agrobac ⁇ terium cells. The result obtained therefore is a complete ly blank membrane without any signals (Fig. 4).
- GUS analysis The presence of the GUS gene (the gene for beta glu- curonidase from E. coli) is analysed in nonfreeze-dried plant material. The activity of beta glucuronidase is analysed on leaf extracts from the regenerated barley plants by visual examination. Determination of the chromosome number:
- Transformed, regenerated barley plants have been obtained from barley microspores treated according to the method described above. A total of 150 barley plants have been regenerated, 10% of which are of albino type.
- Fig. 6 shows a photo of a regenerated, fertile transgenic plant which has been obtained by the method according to the invention.
- Fig. 1 pPCV002: LB and RB are the right and left T-DNA boundary; oriV and oriT, replication start functioning in Agrobacterium; ori, bom, ColEl, replication start and mobilising sequence functioning in E.
- Fig. 2 pCVHPT GUS: LB and RB are the right and left T-DNA boundary; oriV and oriT, replication start functioning in AgroJbacterium; ori, bom, ColEl, replication start and mobilising sequence functioning in E.
- coli Amp ampicillin resistance gene: pNos, nopaline syntase promotor; GUS, ⁇ -Gucuronidase gene; pAocs, sequence for octopine syntase polyA; HPT, hygromycin resistance gene.
- pCVHPT GUS is based on pPCV002.
- Line 1 is DNA from transformed barley plan .
- Lines 2 and 3 are HPT fragments from pCVHPT GUS.
