Climate change will further spread extreme environmental conditions with even higher amplitudes in the future. Because of their sessile life style plants cannot escape the abiotic stresses like water shortage, flooding, low and high temperatures and high salt concentrations. Therefore plants developed strategies to survive harsh conditions by rearranging and adapting the metabolic pathways. The adaptation is based on differential expression of genes that code for proteins involved in protection of cells, tissues and organs. Some genes play key roles and regulate downstream events. The evolution and diversity of those genes is investigated in the project because the data on how these genes and their regulation of expression have developed in the plant kingdom from their ancestor gene will help to explain why some species are well prepared to combat the stresses while others are susceptible. This will help to predict which species could further spread under the changed environment and which species will face problems.
