Definitions

  • Figure 1 provides the 204 amino acid conserved sequence profile identified from comparisons of glycerol-3-phosphate acyltransferase and various lysophosphatidic acid acyltransferase using PSI-BLAST.
  • polynucleotides of the invention can be used as a hybridization probe for RNA, cDNA, or genomic DNA to isolate full length cDNAs or genomic clones encoding a polypeptide and to isolate cDNA or genomic clones of other genes that have a high sequence similarity to a polynucleotide set forth in the Sequence Listing.
  • Such probes will generally comprise at least 15 bases.
  • Preferably such probes will have at least 30 bases and can have at least 50 bases.
  • Particularly preferred probes will have between 30 bases and 50 bases, inclusive.
  • Polypeptides of the present invention include isolated polypeptides encoded by a polynucleotide comprising a sequence selected from the group of a sequence contained in SEQ ID NOs: 1, 3, 5, 7, 9, 10, 12, 14, 16, 18, 20, 22, and 226-233.
  • the inactive precursors generally are activated when the prosequences are removed. Some or all of the prosequences may be removed prior to activation. Such precursor protein are generally called proproteins.
  • the polynucleotide and polypeptide sequences can also be used to identify additional sequences which are homologous to the sequences of the present invention. The most preferable and convenient method is to store the sequence in a computer readable medium, for example, floppy disk, CD ROM, hard disk drives, external disk drives and DVD, and then to use the stored sequence to search a sequence database with well known searching tools. Examples of public databases include the DNA Database of Japan (DDBJ)(http://www.ddbj.nig. ac.jp/); Genebank
  • host cell is meant a cell which contains a vector and supports the replication, and/or transcription or transcription and translation (expression) of the expression construct.
  • Host cells for use in the present invention can be prokaryotic cells, such as E. coli, or eukaryotic cells such as yeast, plant, insect, amphibian, or mammalian cells.
  • host cells are monocotyledenous or dicotyledenous plant cells.
  • antibodies to the acyltransferase protein can be prepared by injecting rabbits or mice with the purified protein or portion thereof, such methods of preparing antibodies being well known to those in the art. Either monoclonal or polyclonal antibodies can be produced, although typically polyclonal antibodies are more useful for gene isolation.
  • Western analysis may be conducted to determine that a related protein is present in a crude extract of the desired plant species, as determined by cross- reaction with the antibodies to the acyltransferase protein. When cross-reactivity is observed, genes encoding the related proteins are isolated by screening expression libraries representing the desired plant species. Expression libraries can be constructed in a variety of commercially available vectors, including lambda gtl 1, as described in Sambrook, et al. (Molecular
  • nucleic acid or amino acid sequences encoding an acyltransferase of this invention may be combined with other non-native, or “heterologous”, sequences in a variety of ways.
  • heterologous sequences is meant any sequence which is not naturally found joined to the acyltransferase, including, for example, combinations of nucleic acid sequences from the same plant which are not naturally found joined together.
  • the Ti- or Ri-plasmid containing the T-DNA for recombination may be armed (capable of causing gall formation) or disarmed (incapable of causing gall formation), the latter being permissible, so long as the vir genes are present in the transformed Agrobacterium host.
  • the armed plasmid can give a mixture of normal plant cells and gall.

Abstract

La présente invention concerne de nouvelles séquences d'acides nucléiques codant les protéines du type acyltransférases, lesdites protéines intervenant activement dans le transfert d'un groupe d'acyles gras entre un donneur d'acyles gras et un receveur d'acyles gras. L'invention concerne également des séquences d'acides aminés et d'acides nucléiques pouvant être obtenues à partir des séquences nucléotidiques de type acyltransférase, et l'utilisation de telles séquences pour l'obtention de cellules hôtes transgéniques capables de produire des compositions à taux de lipides modifiés.
