Abstract
DNA sequences isolated from Nicotiana species (e.g., Nicotiana tabacum and Nicotiana benthamiana) and encoding polypeptides having enzymatic activity for producing phytoene, and the polypeptides encoded, are provided.
Claims4
An isolated nucleic acid molecule encoding a polypeptide having enzymatic activity for producing phytoene, said molecule having a sequence selected from the group consisting of:
- (a) SEQ ID NO:
- 1, SEQ ID NO:3, SEQ ID NO:5, SEQ ID NO:7 and SEQ ID NO:9;
- (b) nucleotide sequences which encode a polypeptide having enzymatic activity for producing phytoene and which hybridize to sequences of (a) above under stringent conditions defined by a wash stringency of 0.3M NaCl, 0.03M sodium citrate, 0.1% SDS at 70.degree. C.;
- (c) nucleotide sequences which encode a polypeptide having enzymatic activity for producing phytoene and which differ from sequences of (a) and (b) due to the degeneracy of the genetic code.
An isolated nucleic acid molecule encoding a polypeptide which has enzymatic activity for producing phytoene, said polypeptide having an amino acid sequence selected from the group consisting of SEQ ID NO:2, SEQ ID NO:4, SEQ ID NO:6 and SEQ ID NO:8.
