The present invention relates to isolated polynucleotides encoding cysteine proteinases; cysteine proteinase inhibitors; and aspartic endoproteinases. The invention also relates to a transformed host cell, preferably a plant cell, in which over- or under-expression of these polynucleotides result in altered levels of coffee flavor precursor levels, specifically, amino group-containing molecules such as amino acids, peptides and proteins, in green coffee grains.

Polynucleotide encoding a cysteine protease

Dehydrin- and late embryogenic abundant (LEA) protein-encoding polynucleotides from coffee plants are disclosed. Also disclosed are a promoter sequence from a coffee dehydrin gene, and methods for using these polynucleotides and promoter sequences for gene regulation and manipulation of flavor, aroma, stress tolerance and other features of coffee beans.
