Abstract:
:PCR-based differential screening was used to identify ethylene-induced genes in deep-water rice (Oryza sativa L.). One of the isolated cDNAs represented a novel protein, OsSBF1, with high homology to mammalian Na+/bile acid transporters and to sodium-dependent transporters from bacteria. One highly homologous protein and three less conserved homologues were identified in Arabidopsis thaliana indicating that Sbf proteins exist in monocot and dicot plant species. Expression of OsSbf1 in deep-water rice was shown to be elevated by growth-inducing treatments. Since bile acids have not been found in plants to date a possible function of SBF proteins may be in the transport of structurally related sulphonated brassinosteroids.
