Plant serine proteases

Abstract

The present invention relates to a genetically modified plant or plant cell derived from a wild-type plant or plant cell, said wild-type plant or plant cell producing at least one serine protease comprising the motif SSRGPX1LKPDX2X3APGX4SGTSMSCPHX5PX6WSPX7AX8X9SAX10MTT (SEQ ID No. 1), wherein X1 is a peptide consisting of 7 amino acid residues, X2 is I or L, X3 is T or M, X4 is a peptide consisting of 27 or 28 amino acid residues, X5 is a peptide consisting of 12 amino acid residues, X6 is T or E, X7 is S or A, X8 is V or I, X9 is K or R and X10 is I or M, wherein the proteolytic activity of the at least one serine protease in the genetically modified plant or plant cell is reduced compared to its activity in the wild-type plant or plant cell, wherein the genetically modified plant or plant cell comprises at least one exogenous nucleic acid molecule encoding for at least one protein or polypeptide of interest.
