1 Abstract This article presents a process for the reengineering of computer-based control systems, and describes tools that automate portions of the process. The intermediate representation IR for capturing features of computer-based systems during reverse engineering is presented. A novel feature of the IR is that it incorporates the control system(More)
Chlorophyll (Chl) degradation occurs naturally during leaf maturation and senescence, and can be induced by stresses, both processes involving the regulation of plant hormones. The objective of this study was to determine the functional roles and hormonal regulation of a gene encoding pheophytin pheophorbide hydrolyase (PPH) that catabolizes Chl degradation(More)
