Conteúdo: |
Post-harvest physiological deterioration (PPD) is a major contraint on the marketability and use of cassava. The physiological and biochemical changes observed during PPD show strong parallels with wound responses in other plants, except for the lack of extensive wound healing. Increased gene and enzyme activity of phenylalanine ammonia-lyase (PAL) has been measured in cassava roots during PPD. PAL is the first and key enzyme of the core pathway of general phenylpropanoid metabolismm, which plays pleiotropic roles in development and stress responses, including the production of isoflavonoid phytoalexins, flavonoid pigments, UV protectants, lignin, suberin, and signalling molecules such as salicylic acid. |
