High impact information on VAR3

  • The VAR3 gene, isolated by transposon tagging, encodes the 85.9 kDa VAR3 protein containing novel repeats and zinc fingers described as protein interaction domains [1].
  • The stable, recessive Arabidopsis variegated 3 (var3) mutant exhibits a variegated phenotype due to somatic areas lacking or containing developmentally retarded chloroplasts and greatly reduced numbers of palisade cells [1].


  1. Arabidopsis VARIEGATED 3 encodes a chloroplast-targeted, zinc-finger protein required for chloroplast and palisade cell development. Naested, H., Holm, A., Jenkins, T., Nielsen, H.B., Harris, C.A., Beale, M.H., Andersen, M., Mant, A., Scheller, H., Camara, B., Mattsson, O., Mundy, J. J.
