POLYNUCLEOTIDE SEQUENCE OF FRUIT SOFTENING ASSOCIATED B-D-N- ACETYLHEXOSAMINIDASE AND ITS USES FOR ENHANCING FRUIT SHELF LIFE

摘要

The present invention provides isolated polynucleotide sequences encodingβ-D-N-acetylhexosaminidase. The present invention further provides DNA construct comprising the polynucleotide sequence coding forβ-D-N-acetylhexosaminidase in sense or antisense orientation, RNAi construct, recombinant vector comprising the construct and host cells comprising the recombinant vector disclosed in the present invention. The present invention further provides transgenic plant, plant cell, transgenic progeny and seeds expressing the polynucleotide with reducedβ-D-N-acetylhexosaminidase protein accumulation, having enhanced fruit shelf life.
