Abstract | Osmotic stress causes many adverse symptoms in plants, which include, for� example, growth limitation and decrease or even absence of yield. Proteomic analyses of plant responses to stressors could lead to the introduction of crops with high resistance to osmotic stress. Such plants would be characterized by high yield even under unfavorable environmental conditions. In this article we describe changes in the protein profiles occurring in response to mild and moderate osmotic stress in triticale roots. Analysis of the protein profiles of these roots showed an increased abundance of 14 and a decreased abundance of 11 proteins under mild osmotic stress conditions while a moderate osmotic stress caused an increased abundance of 18 and a decreased abundance of 33 proteins. Twenty-five proteins, whose quantity altered under stress were identified using MALDI-TOF mass spectrometry. The identified proteins were classified into the categories of proteins associated with: defense mechanisms, metabolism, transcription, cell structure, protein synthesis, transport and signal transduction. The functions of identified proteins were discussed in relation to osmotic stress. Some of the identified proteins may be responsible for the adaptation of plants to adverse conditions. |
