AB  - Incidence of natural light stress renders it important to enhance our 
      understanding of the mechanisms by which plants protect themselves from harmful 
      effects of UV-B irradiation, as this is critical for fitness of land plant 
      species. Here we describe natural variation of a class of 
      phenylacylated-flavonols (saiginols), which accumulate to high levels in floral 
      tissues of Arabidopsis. They were identified in a subset of accessions, 
      especially those deriving from latitudes between 16 degrees  and 43 degrees  North. Investigation 
      of introgression line populations using metabolic and transcript profiling, 
      combined with genomic sequence analysis, allowed the identification of 
      flavonol-phenylacyltransferase 2 (FPT2) that is responsible for the production of 
      saiginols and conferring greater UV light tolerance in planta. Furthermore, 
      analysis of polymorphism within the FPT duplicated region provides an 
      evolutionary framework of the natural history of this locus in the Brassicaceae.
