Analysis of thermostability of mitochondrial dehydrin-like proteins. The results of the analysis are shown for mitochondrial proteins isolated from yellow lupin hypocotyls (A) as well as from cauliflower inflorescences (B) and Arabidopsis cell cultures (C). Lupin mitochondria were isolated from seedlings growing in control conditions and from plants submitted to cold stress (as indicated on panel A). The thermostability of dlps was assayed at different temperatures (room temperature- RT, as well as 60, 80 and 100°C). Ten micrograms of mitochondrial proteins were loaded per lane. Western analysis was carried out using the antibody against the K-segment of dehydrins (@K). The representative Western blot came from 3 experimental repetitions.
