- A novel aspartic acid protease gene from pineapple fruit (Ananas comosus): cloning, characterization and relation to postharvest chilling stress resistance (2013), J. Plant Physiol., 170, 1536-1540.
Application
| EC Number | Application | Comment | Organism |
|---|---|---|---|
| 3.4.23.40 | food industry | gene expression under postharvest chilling treatment in two pineapple varieties differing in their resistance to blackheart development reveals opposite trends. The resistant variety shows an up-regulation of AP1 precursor gene expression whereas the susceptible shows a down-regulation in response to postharvest chilling treatment. The same trend is observed regarding specific aspartic protease enzyme activity in both varieties | Ananas comosus |
