| Research Abstract |
GmTDF-5, a salt-inducible gene of soybean, encodes an armadillo-repeat protein of unknown function. In this study, we characterized molecular features of GmTDF-5 and its homologs to understand their physiological roles in the salt tolerance and response of soybean. The results revealed that (i) LjTDF-5, a GmTDF-5-homolog from the model legume Lotus japonicus, shows molecular structures and stress response similar to GmTDF-5, (ii) overexpression of GmTDF-5 gene increases expression of the salt-/drought-inducible gene(s) and (iii) the level of GmTDF-5 protein is controlled through the ubiquitin-proteasome degradation.
