Isolation and characterization of the EF-1 alpha gene of the filamentous fungus Puccinia graminis f. sp. tritici.

Abstract:

:A gene of Puccinia graminis f. sp. tritici, coding for the translation elongation factor 1 alpha (EF-1 alpha), was isolated from a P. graminis genomic library using the EF-1 alpha gene sequence of Absidia glauca. The coding region of 1389 nucleotides encodes a polypeptide of 463 amino acids and is interrupted by eight introns. An additional intron is located in the 5' untranslated region. A single transcription start point (tsp) was mapped by primer extension. A cDNA fragment corresponding to P. graminis EF-1 alpha mRNA hybridized with a 1.9-kb-long poly(A+)RNA, sufficient to encode the EF-1 alpha protein. Southern hybridization of digested genomic DNA revealed that two copies of the EF-1 alpha gene exist in the genome of P. graminis.
