Biodiversity and salinity tolerance mechanisms of Romanian wild plants

Summary

        Soil salinity is one of the most important abiotic stress factor reducing crop productivity worldwide, limits plant growth and survival, and restricts the use of arable land. Adaptation to salt stress requires coordinate changes in metabolism, cell growth, division, and differentiation, which depend on a large set of genes controlling complex regulatory mechanisms. The principal purpose of this project is to identify the biodiversity and different adaptation mechanisms of salt resistant wild plant species from Romania. After identifying the salt tolerant species, anatomical, physiological, biochemical and genomic adaptation mechanisms will be explored. Finally, salt stress responsive genes will be identified and the evolutionary conservation of salt stress responsive genes will be examined. An appropriate knowledge of the adaptation mechanisms involved in the response of plants to adverse environmental conditions is the first step in generation of crops with higher tolerance to stress. Interdisciplinary research at the level of whole plant, cells, genes, proteins and metabolites constitute the basis of understanding the plant stress adaptation mechanisms. The results obtained from research of salt tolerant wild plant species could be exploitable in growing crops in salinity conditions.
