Understanding the physiological limitations to yield formation and the adaptations of plants to abiotic stresses such as drought. The current research emphasis is on wheat, although past work involved maize, oats, sugar beet and tropical legumes. New information and tools are needed to increase food production and the effective use of water.
One key area is identifying superior germplasm under field conditions using advanced phenotyping techniques. This work is done in close collaboration with commercial plant breeders. Other related projects were initiated in response to needs by the agriculture industry and funded almost entirely by industry partners. Earlier work involved studying the role of drought-induced abscisic acid (ABA) in regulating maize endosperm development and cell division, kernel growth, and genes for carbohydrate metabolism and storage proteins.
Further studies were on the role of ABA in regulating maize root growth maintenance, osmotic adjustment, and signalling changes in rhizosphere water availability at the cell membrane level. Root tissue O2 relations were also studied by inventing an O2 microsensor. Expertise is in the areas of crop physiology, field phenotyping, plant water relations, regulation of growth and grain development during water deficit, and hormonal regulation of root growth and osmotic adjustment.
