Abstract: Methods and compositions for increasing tolerance to abiotic stresses in plants are provided. One embodiment provides a method for increasing salt tolerance in a plant by treating the plant with an amount of 2-keto-4-methylthiobutyric acid (KMBA) effective to increase salt tolerance in the plant relative to an untreated plant. Typically KMBA is in an aqueous solution used to irrigate the plant, seed, or seedling. In a preferred embodiment, the aqueous solution is a salt solution, including but not limited to seawater. The KMBA is typically present in the aqueous solution at 1.0 to 250 nM, preferably at least 100 nM.

Abstract: Compositions containing Enterobacter sp. SA187 and methods of use thereof to enhance plant development and yield under environmental stress conditions such as heat stress, are provided. The compositions include plant substrates containing an effective amount of Enterobacter sp. SA187 to inhibit or reduce abiotic stress in the plant. In a preferred embodiment suitable plant substrates include, but are not limited to soil, peat, compost, vermiculite, perlite, sand, clay and combinations thereof. Another embodiment provides plants inoculated with an amount of SA187 to provide abiotic stress tolerance, enhance yield, enhance biomass, or a combination thereof. Examples include non-desert plants which include but are not limited to crop plants that are not indigenous to desert environment.
