The invention relates to a method to change the capacity of a plant for adaptation to changes in the zinc concentration in the environment, especially the soil, comprising providing said plant with a nucleotide according to SEQ ID NO:1 or SEQ ID NO: 2 or an ortholog thereof. Such a method is especially useful to decrease Zn deficiency or to (hyper)accumulate Zn in plants for bioremediation or for biofortification. Transgenic plants for these proteins are also disclosed.

This invention discloses a DNA fragment encoding a protein comprising the amino acid sequence depicted in FIG. (SEQ ID NO:5), or a protein substantially homologous therewith and involved in fatty aldehyde decarbonylase activity. Said DNA fragment may have the nucleotide sequence depicted in FIG. (SEQ ID NO:2) or a homologous nucleotide sequence. Further this invention discloses a promoter of said DNA fragment having the nucleotide sequence depicted in FIG. (SEQ ID NO:4). Using said fragments transformed organisms can be produced showing an altered epicuticular wax composition.
