DESCRIPTION:MADS-box transcription factors regulate several aspects of pla
 nt reproductive development\, such as the transition from vegetative to re
 productive phase and floral organ formation. Although this gene family has
  been extensively studied in plants\, relatively little attention has been
  given to the influence of splicing on the evolution and the regulation of
  MADS-box transcription factors. I will present some of my previous work t
 hat provides two examples of how splicing can effect protein activity\, by
  influencing protein-protein interaction specificity. In one case a splici
 ng error\, around 120 million years ago\, introduced an additional amino a
 cid at a crucial protein-protein interaction interface and thereby changed
  a MADS-box protein’s ability to specify reproductive organs. In a secon
 d example I will show how environmental conditions can influence a splice 
 site to modulate the availability of a MADS-box transcription factor invol
 ved in the decision to flower.
