This project focused on the identification of membrane proteins involved in salinity tolerance in the halophyte Salicornia bigelovii. Salicornia bigelovii plants were treated with 0, 50, 200, and 600 mM NaCl for 6 weeks. Membrane preparations for each treatment were obtained in triplicates and were separated into 12 fractions per sample through a continuous sucrose gradient. Based on protein relative abundances per fraction, organellar membrane proteomes were generated. Protein abundances were also compared across treatments.
