Abstract: Post-harvest biotechnology is a fast growing field of plant biotechnology. Achievements were made in the field to delay or prevent fruit ripening and softening by genetic manipulation of ethylene and cell wall metabolism. Despite the development of transgenic plants with the desired traits, the technology has not achieved the pace due to drawbacks of the existing strategies to effectively control the developmental processes following harvest. Here the authors analyse various strategies of post-harvest biotechnology and prospects, giving special emphasis to the metabolic interactions of pathways related to post-harvest characteristics-- those of polyamine and ethylene-- and the engineering of polyamine metabolism as an alternate strategy for post-harvest biotechnology by carefully manipulating the delicate metabolic balance and the benefits of the newly proposed strategy over the currently used ones.
