Proline accumulation in three closely related Salsola L. taxa

Halophytes, gypsicoles and serpentinicoles are adapted to specialized edaphic conditions at arid semi-arid regions. These areas possess physical chemical stress factors for all plants. For these plants, one of the most important parameter that provides tolerance is proline accumulation. Proline a water-soluble amino acid generally accumulated under behave like an indicator adaptation plants against extreme conditions. In this study, amounts accumulation in three different taxa, Salsola boissieri subsp. serpentinicola, turcica, were determined. taxa phylogenetically close each other but soil types. The highest measured leaves S. turcica with value 2.510 ± 0.020 µmol g-1 FW lowest serpentinicola 0.996 0.024 FW. As result accumulations, it can be concluded high amount halophytic response low means species may have adaptations caused by serpentinicolous soils. Both studied accumulate findings show marker assessment species.
