DESCRIPTION:\nThe circadian clock serves to coordinate physiology and beha
 viour in a wide range of organisms with its daily cycles derived from the 
 rotation of the earth (McClung\, 2013). In plants\, circadian rhythms cont
 ribute to growth and yield and\, hence to agricultural productivity (Dodd 
 et al.\, 2005). We are investigating the effect of the wheat orthologues o
 f A. thaliana core circadian clock genes on yield potential and contributi
 ng agronomic traits in wheat\, providing an assessment of the viability of
  circadian tools for agronomic improvement.\n\nAfter having identified the
  wheat orthologues of the circadian clock genes\, I am currently conductin
 g association mapping to link circadian clock genes with relevant traits. 
 I am screening the identified circadian clock genes for variation between 
 the MAGIC parents to develop high quality sub genome specific circadian cl
 ock markers. These and an existing set of markers are being used to associ
 ate circadian clock genes with phenotypes in a winter wheat Multi Parent A
 dvanced Inter Cross (MAGIC) population. I have also optimized a high throu
 ghput delayed chlorophyll fluorescence assay to detect and resolve novel q
 uantitative trait loci affecting circadian rhythms.\n\nMcClung\, C. R. Bey
