High impact information on PFN2/PRF2/PRO2

  • The vegetative class profilins, PRF1, PRF2, and PRF3, are expressed in vegetative organs [1].
  • To further investigate the different roles of the first two introns on gene expression, the first introns were exchanged between PRF2 and PRF5 [1].
  • Analysis of pfn promoter-GUS fusion genes in transgenic Arabidopsis shows that pfn2 is specifically expressed in the vascular bundles of roots, hypocotyls, cotyledons, leaves, sepals, petals, stamen filaments and stalks of developing seeds, whereas expression of pfn4 is restricted to mature and germinating pollen grains [2].
