Abstract
The present invention provides an isolated DNA sequence which encodes at least part of the tomato enzyme endopolygalacturonase PG1 beta-subunit. This DNA sequence preferably encodes a polypeptide, the N-terminal amino acid sequence of which is: E-K-H-S-G-D-I-H. In other preferred forms of the invention the DNA sequence encodes a polypeptide which includes one of the following amino acid sequences: E-K-H-S-G or N-Y-G-Q-X-F-N-E-G. The DNA sequence of the present invention may be used to produce genetically engineered tomato plants with modified ripening characteristics.
