Résumé
Plants suffering from drought go through adaptations to survive such periods. One of these adaptations is to produce proteins called dehydrins, the functions of which are still under investigation. In this study, dehydrins of wheat (Triticum aestivum L. cultivar Arina) as an important crop plant were analyzed under heavy drought conditions and during the following recovery phase. The method of immunoblotting was used to determine changed dehydrin patterns. Several dehydrins with molecular weights of 180 (double band) 58, 42, 24 and 20 kDa were detected in plants grown on soil (stressed by withholding water). The clearest bands were always observed in young leaves. Dehydrin levels decreased again during a subsequent recovery phase.
