DESCRIPTION:Understanding the physiological limitations to yield formation
  and the adaptations of plants to abiotic stresses such as drought. The cu
 rrent research emphasis is on wheat\, although past work involved maize\, 
 oats\, sugar beet and tropical legumes. New information and tools are need
 ed to increase food production and the effective use of water.\nOne key ar
 ea is identifying superior germplasm under field conditions using advanced
  phenotyping techniques. This work is done in close collaboration with com
 mercial plant breeders. Other related projects were initiated in response 
 to needs by the agriculture industry and funded almost entirely by industr
 y partners. Earlier work involved studying the role of drought-induced abs
 cisic acid (ABA) in regulating maize endosperm development and cell divisi
 on\, kernel growth\, and genes for carbohydrate metabolism and storage pro
 teins.\nFurther studies were on the role of ABA in regulating maize root g
 rowth maintenance\, osmotic adjustment\, and signalling changes in rhizosp
 here water availability at the cell membrane level. Root tissue O2 relatio
 ns were also studied by inventing an O2 micro-sensor. Expertise is in the 
 areas of crop physiology\, field phenotyping\, plant water relations\, reg
 ulation of growth and grain development during water deficit\, and hormona
 l regulation of root growth and osmotic adjustment.\n\nDue to having to go
  online\, we are restricting the talks to University of Cambridge and alum
 ni to keep them as informal as possible.\n\nContact reception@plantsci.cam
