Conteúdo: |
The elongation factor protein eEF1A appears to be a multifunctional protein in eukaryotes, where it serves as a protein synthesis factor as well as a cytoskeletal protein. In maize endosperm, the eEF1A concentration is highly correlated with lysine content, and eEF1A synthesis is increased in opaque2 mutants compared to wild type plants. To investigate the basis for the increased synthesis of eEF1A in opaque2, genes encoding this protein were characterized and their relative level of expression in endosperm and other tissues was investigated. Maize contains 10 to 15 eEF1A genes that are nearly identical in nucleotide and amino acid sequences. However, these genes can be distinguished based on their 3' non-coding sequences, which are less conserved. By screening endosperm and seedling cDNA libraries, it was shown that the relative level of transcripts of maize eEF1A genes varies in different tissues. At least five genes are transcribed in the endosperm, with 2 accounting for ca. 80% of the RNA transcripts. The expression of several genes is enhanced in opaque2 endosperm, although the significance of this is unclear. Nucleotide sequence data have been submitted to the EMBL/DDBJ/GenBank databases under the accession numbers AF136823 to AF136829 for eEF1Aa, eEF1Ab, eEF1Ac, eEF1Ad, eEF1Ae, eEF1Af and eEF1Ag, respectively.. |
