Genetic analysis of environmental stress-tolerance in plantsEach year there are extensive losses in crop productivity caused by abiotic stresses. Limited tolerance to extremes in temperatures, drought, salinity and nutrient imbalances have traditionally restricted the cropping alternatives available to growers and threatened the sustainability of agriculture. Understanding the genetic basis of environmental stress tolerance and genetic improvement of crop species can enhance productivity, expand crop production into previously non-economically viable areas and reduce the need for expensive inputs with possible environmentally damaging consequences. Many plant species show remarkable tolerance to environmental stresses, including high salinity, drought and temperatures below -20°C. The molecular analysis of the plant's response to drought, salt stress, and freezing have shown that there is a large number of genes that are up-regulated in response to these stresses. Some of stress-responsive genes are regulated by common signalling pathways that act in response to different stresses and others are regulated by pathways that are unique to specific stresses. Many of the stress-regulated genes are themselves regulatory genes. We study the adaptation to environmental stress in wheat, Triticum aestivum, one of the most important crops world-wide. We carry out both molecular analysis of stress-regulated genes and genomic analysis of the stress response for large-scale gene discovery. Our current work focuses on signalling pathways that are mediated by the interaction of GTP binding proteins (G proteins), calcium binding proteins and phospholipase C's. These stress regulated genes encoding these proteins initially were discovered in wheat, and in a closely related and highly salt-tolerant wild wheatgrass Lophopyrum elongatum. To further characterize the effects of these genes on plant growth and resistance to environmental stress we characterize the homologs of the cereal genes in Arabidopsis lines in which the genes have been mutated or over-expressed.
Our second major area of research is in genomic research of wheat and closely related species in the tribe Triticeae. We characterize expressed sequence tags (ESTs) generated from large-scale first and second generation sequencing of cDNA. Gene discovery is directed toward the identification of signalling and regulatory genes whose expression is induced or repressed by environmental stress and the characterization of homeologous gene expression in polyploidy plants.
