Abstract: The present invention relates to a transgenic plant comprising one or more plant cells transformed with exogenous nucleic acid encoding a Dunaliella salt-inducible or salt-responsive protein selected from the group consisting of elongation initiation factor 3 (eIF3), NADPH dependent quinone reductase (QOR), aldo-keto reductase (AKR), bifunctional aspartate kinase-homoserine reductase (AK-HSD) and mitochondrial import membrane translocase subunit (TIM9), or a fragment, homolog or variant thereof. The transgenic plant has increased tolerance to salt as compared to a corresponding non-transgenic plant.
