Putative cardenolide biosynthetic in C. procera.
The pathway has been divided into three subgroups as terpenoid backbone biosynthesis, steroid biosynthesis and cardenolide biosynthesis. The enzymes with corresponding unigenes are mapped. Fold induction is represented by + sign; 0–2(+), 2–4(++), 4–10(+++), >10(++++) Full names of genes are mentioned in Supplementary Table 4.
