Plant DNA Variation and Stress

  • C. A. Cullis
Part of the Stadler Genetics Symposia Series book series (SGSS)


The generation of quantitative DNA changes in the flax variety Stormont Cirrus in response to various stresses is described. Members of all the highly repetitive sequence families have been cloned and used as probes to characterise this variation. The variation occurs in a particular subset of the genome, irrespective of the stress applied, although the frequency with which a family of sequences varies may depend on the particular stress applied. In the case of the 5SRNA genes a specific labile set of these sequences which frequently undergoes deletion was detected. The evolutionary consequences of such an interaction between the genome and the environment are considered.
