Definitions

  • the term "repression domain of the Drosophila engrailed gene (eng)” means a fragment of the Drosophila engrailed gene or of a derivative sequence thereof, said fragment comprising a nucleotide sequence that encodes a polypeptide interfering with the general transcription machinery and transcriptional activators. Said fragment advantageously comprises a minimal repression sequence coding for a polypeptide of 55 residues (Poole et al., 1985, Han K. et al., 1993). The whole engrailed gene may also be used but most preferably without its homeodomain.
  • Engrailed related domains which share the same repression activity, may also be used, such as those described in Smith et al. (1996).
  • the repressor sequence that is used may be a sequence that codes for at least the Kruppel-associated box-A (KRAB-A) domain of zinc finger proteins (Witzgall et al., 1994) for at least the RE-1- silencing transcription factor (REST) (Thiel et al., 1998), or for at least the BTB (for Broad-complex Tramtrac and Brie) domain, also known as POZ-domain (Ahmad et al., 1998 ; Huynh & Bardwell, 1998).
  • KRAB-A Kruppel-associated box-A domain of zinc finger proteins
  • REST RE-1- silencing transcription factor
  • BTB for Broad-complex Tramtrac and Brie domain
  • said transcription factor may preferably be selected from the group consisting of : STM ("Shootmeristemless"), member of the Knotted class of homeodomain proteins, which is an essential gene for development and function of the shoot apical meristem ;
  • ZmHox - member of the homeobox proteins more particularly ZmHox 1a/1 b and 2a/2b, which are expressed in maize meristems and proliferating cells from the early embryo to late reproductive organs. This expression pattern suggests a contribution to plant growth and morphogenesis;
  • Arabidopsis is a transcription factor belonging the family recently described as ARF1 family for Auxin Response Factor 1 (Ulmasov et al., 1997). Ms41-A analogues may also be used, such as those described in WO 97/23618 or the Arabidopsis gene Monopteros which encodes a transcription factor mediating embryo axis formation and vascular development (Hardtke et al., 1998), and the Arabidopsis gene ETTIN involved in floral development (Sessions, 1997).
  • the plants transformed with a chimeric DNA construct of the invention comprising such Ms-41-A factor are expected to be male sterile.
  • the promoter that is used is a tissue- specific promoter or a developmentally regulated promoter. This allows a conditional loss of functions that may be desired, for example to design new plant varieties.
  • 35S promoter or advantageously the double 35S constitutive promoter of CaMV as described in Kay et al. (1987) ; rice actin promoter followed by the rice actin intron (PAR- IAR) included in plasmid pAct1-F4 as described in Mc Elroy et al. (1991); the constitutive promoter EF-1 ⁇ of the gene encoding for plant elongation factor described in WO 90/02172 or in Axelos et al.
  • HMWG promoter High Molecular Weight Glutenin from barley (Anderson et al., 1989) ; the promoter of maize ⁇ zein (P ⁇ zein) included in p ⁇ 63 plasmid in Reina et al. (1990) allowing the expression in albumen of maize seeds ;
  • PGEA1 and PGEA6 promoters corresponding to the non coding 5' region of the genes GEA1 and GEA6, expressed in the grains in Arabidopsis thaliana (Gaubier et al., 1993) ; and ⁇ -phaseolin promoter (Riggs et al., 1989). • specific promoters which drive expression in particular plant tissues which are involved in the control of fertility :
  • parts of transgenic plants refer in particular to leaves, fruits, seeds, roots or cells that have been genetically transformed.
  • the preferred plants that are used for transformation may be for example selected from the group consisting of Arabidopsis thaliana, rice, tobacco, maize, Brassica, wheat, tomato and flowers (Petunia, rose, carnation).
  • Figure 5 represents a eng-STM construct.
  • Figure 6 represents a eng-AP3 construct.
  • the homeodomain of STM was removed in an independent experiment.
  • the plasmid pRT ⁇ eng-STM was first partially digested with Hindll, secondly to completion with BamHI and ends were ligated after fill in reaction with Klenow enzyme.
  • Plants are regenerated from these callus by modifying the hormonal and osmotic equilibrium of the cells according to the method described by Vain et al, 1989.
  • a method of genetic transformation leading to a stable integration of the modified genes in the genome of the plant involves the use of a gene gun.
  • the target cells are fragments of callus having a surface area of 10 to 20 mm 2 .
  • the fragments are laid in the center of a Petri dish containing a culture medium identical to the initiation medium, further containing 0.2 M of mannitol + 0.2 M of sorbitol (16 fragments per dish). Tissues are then bombarded as previously described.
  • the dishes are then sealed using Scellofrais® and cultivated in dark at 27°C.
  • the first planting is effected 24 hours afterwards, then every two-weeks during three months in a medium identical to the initiation medium but containing a selective agent.
  • the selective agents may be for example active ingredients of herbicidal agents (Basta®, Round up®) or antibiotics (hygromycin, kanamycin).
  • Example 5 Expression of the endogenous STM and AP3 genes
  • transgenic eng-STM or eng-AP3 phenocopy plants were subjected to RNA gel blot and RT-PCR analysis.
  • the chimeric transcripts derived from the CaMV 35S promoter were easily detectable in total or poly(A) + RNA from pooled seedlings or flowers (12 individual progeny) probed with the STM or AP3 coding regions.
  • the high abundance of chimeric transcripts interfered with the detection of the shorter native mRNA in these gel blot experiments.
  • Discrimination was achieved by probing with the natural 3'UTR sequences that are lacking in the transgenes. The result obtained for the STM 3'UTR confirms transcription of the native STM gene although at a significantly reduced level.
  • Example 6 Phenocopies rely on the incorporation of the chimeric eng-STM protein into the nuclear compartment Although the changes in size or identity of the expressing organs might explain the lower transcript levels observed in stm and ap3 phenocopy plants we aimed to elaborate further evidence against homology based gene silencing.
  • the chimeric eng-STM polypeptide therefore was expressed in C- terminal fusion with the hormone-binding domain of the glucocorticoid receptor in transgenic Arabidopsis plants. Due to this addition the resulting eng-STM-GR polypeptide should be cytoplasmatic and incorporated into the nuclear compartment only after hormone application. A linkage between the dexamethasone treatment and alterations in SAM activity thus should depend on the nuclear import of the chimeric eng-STM-GR protein and be incompatible with cosuppression.
