Resumen:
Boysenberry (Rubus hybrid) fruit were harvested at 5 developmental stages from green to purple and changes in cell wall composition during development were analyzed. The results suggest that cell wall disassembly accounts for at least 3 stages: an early stage associated with cellulose the metabolism of cross-linking glycans, an intermediate period characterized by a large increase in pectin solubilization without depolymerization in which arabinose is lost and a final stage characterized mainly by a reduction of galactose and a dramatic increase in pectin depolymerization. From a biotechnological perspective enzymes involved in pectin matrix disassembly seem to be the better candidates to affect boysenberry fruit late softening by genetic intervention.
