The present invention provides transgenic plants transformed with exogenous nucleic acid encoding aplasma membrane (PM)-ATPase. The transgenic plant has increased tolerance to salt as compared to a corresponding non-transgenic plant. The present invention also provides nucleic acids encoding a chimeric PM-ATPase, which comprise a first portion encoding a plant PM-ATPase or a fragment thereof, and a second portion encoding aPM-ATPase or a fragment thereof. The present invention also discloses a method of producing a transgenic plant having an increased tolerance to salt as compared to a corresponding non-transgenic plant, a method of modifying a plant capacity to survive salt shock, and a method of modifying plant recovery after exposure to salt stress, by introducing into one or more cells of a plant an exogenous nucleic acid encoding aPM-ATPase. Also provided by the present invention are plant cells comprising an exogenous nucleic acid encoding aPM-ATPase, and plant seeds and progeny obtained from the transgenic plants.

Salt resistant transgenic plants

The present invention relates to transgenic plants resistant to parasites that their normal life cycle includes feeding on the plant cytoplasm, including insects, nematodes and fungi, wherein the plants are engineered to produce small interfering RNAs (siRNAs) capable of silencing a parasite specific gene. Particularly the parasite gene is a stage-specific gene, more particularly a gene involved in essential, early developmental stages of the parasite in or on the plant.

Plants resistant to cytoplasm-feeding parasites

The present invention provides transgenic plants transformed with exogenous nucleic acid encoding asalt-inducible or salt-responsive protein selected from the group consisting of eukaryotic initiation factor 3 (eIF3) subunit, 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 plants have increased tolerance to salt as compared to corresponding non-transgenic plants. The present invention further provides nucleic acids, constructs and vectors encoding thesalt-inducible or otherwise salt-responsive proteins, and to a method of producing transgenic plants having an increased tolerance to salt, a method of modifying plant capacity to survive salt shock, and a method of modifying plant recovery after exposure to salt stress, by introducing the nucleic acids, constructs and/or vectors into one or more cells of the plant.
