DESCRIPTION:Sugar beet\, Beta vulgaris ssp. vulgaris\, is the UK’s local
  source of sugar and provides for half of our domestic sugar needs. Sugar 
 beet is a biennial plant\, grown as an annual spring-sown crop. The roots\
 , a product of the vegetative phase of growth\, contain up to 19% sugar an
 d are harvested in the autumn. Bolting (stem elongation) and flowering of 
 crops reduces root yield and occurs after crops experience prolonged cold 
 temperatures (vernalization) in the spring. The gibberellin plant growth r
 egulators have roles in cell expansion and division\, and the control of r
 eproductive growth. In biennial sugar beet\, the amount of bioactive gibbe
 rellins increases at the shoot tip after vernalization\, and bolting has b
 een shown to be a GA-limited process. What is not yet clear is the mechani
 sm of interaction between vernalization\, gibberellin and bolting or flowe
 ring. I will show how qPCR has revealed a vernalization-regulated GA biosy
 nthetic enzyme in beet\, and how a transcriptomics approach has provided k
 ey findings for my work on bolting beet going forward.
